[0051]
[0052]
[0053]
[0054] Naturally many forces that move mass and energy in the water drive processes occurring in the seas and oceans. Some of the forces moving the water mass include gravity, buoyancy, convection and turbulence or disordered flow due to transfer of kinetic energy from wind to the ocean surface or tidal forces driven by earth-moon gravitational pull and waves driven by the rotation of earth and generation of ocean gyres due to resultant action of Coriolis and multiple forces. While the heat in the system is moved along with mass driven by convection, diffusion and thermal balance amongst others. These forces tend to keep the heat near the surface, this is because the heating is predominantly by sunlight on the surface, and then constrained to remain there driven mainly by the stratification of water due to temperature profile 104 which in itself gives lower density due to expansion of water on the surface as shown in 103, in addition the input of fresh water on the surface from rains and rivers lead to lower salinity and density as shown in 107 and 103 respectively. The salinity and density rise quickly moving towards the bottom, due to sinking of the dissolved solids, this further increases the sharp nature of density drop. As a result of these natural processes, the trio of Halocline, Thermocline and Pycnocline are well defined regions which together lead to a steady state profile of lower density and salinity on the surface which in turns keep the heat collected at the surface confined to the top region. This stratification makes vertical transfer of heat and mass difficult and gives poor mixing of oceans due to naturally occurring currents and flows.
[0055] The turbulent processes driven by wind and wave coupling are also not very strong and prevalent due to poor coupling between the atmosphere and ocean, driven mainly by interactions on rough surfaces or near land masses. The low coupling of energy leads to poor direct correlation of parameters and also slow and inefficient mixing across the depth due to these natural processes. Thus the wind interaction does not break the stratification.
[0056] This stratification leads to heating of the mainly the top few hundred of surface layers of water, since this is a limited amount of water mass, it has effectively lower thermal capacity and as a result for a given amount of extra energy input the surface temperature rises faster than they would have if there was better mixing of water. Thus with natural processes there is strong stratification and confinement of the heat to the surface as a result the global temperature is on an average increasing at roughly 0.14 degrees Celsius per decade!
[0057] Thus, there are numerous reasons for naturally occurring sea surface temperature to increase rapidly with currently occurring processes, which are addressed by concepts, described herein below. These reasons include [0058] Heating of surface water by absorption of solar energy on top. [0059] Injection of fresh water on surface due to precipitation or due to rivers and ice melting, this leads to low salinity water on the surface. [0060] Steep changes on surface of salinity and temperature give rise to sharp reduction of the density on the surface of oceans. [0061] These surface profiles lead to stratification of surface water, driven by Thermocline, Halocline and Pycnocline regions stabilizing each other. [0062] Stable stratification of seawater gives poor vertical mixing of waters.
[0063] As a result of this the energy is confined to the surface.
[0064] As only surface is actively collecting the heat the effective thermal capacity of the ocean is reduced by an order of magnitude, and the surface sea temperature rises quickly.
[0065] The shortcomings of the naturally occurring processes may be overcome and additional advantages are provided by embodiments of this invention, through the provision of a method of modifying and cooling the surface of the planet, where renewable energy is applied to work to counteract the impact on temperatures, humidity, wind and ocean currents. In an embodiment, this method consists of building machineries to move heat away from the surface of the planet, specifically reduce the Surface Sea Temperature (SST) and by doing so reduce the global temperatures and modify the weather and climate. This is achieved by pushing the heat accumulating into the oceans, deeper into the lower waters. By mixing the heat into the oceans better, the rate of average surface temperature rise can be slowed down by nearly an order of magnitude. This is done by recognizing that surface sea temperature (SST) is a key factor determining the local weather and in general short and long-term climatic conditions, a way to control SST and mixing of Oceans will help slow down the immediate temperature rise and climatic change.
[0066] Generally stated, disclosed herein below are methods for reducing the rate of rise of surface sea temperature by moving the extra heat away from the surface deeper into the ocean waters.
[0067] If the entire body of water in ocean was well mixed, thus the profiles 103, 104, 107 and 108 would not have the sharp structure near the surface, instead there would be a smooth shape of profiles for density, salinity increasing while the temperature decreasing with higher depths. With vertical mixing of waters or movement of heat, the extra heat due to greenhouse gases that is currently accumulating near the surface will get evenly distributed throughout the depths of oceans. This would mean that the temperature rise would be contained by the total thermal capacity of ocean. As can be seen this is much larger amount, higher by nearly an order of magnitude. If the heat is moved deeper into the ocean, calculations show that for the current rate of extra heating, the temperatures of the entire ocean, including that of sea surface, would rise by only 0.017 degrees Celsius each decade! This would be significant slowing down of the present heating trends and will be critical to slow down the processes currently hastening towards a warmer global climate. The runway heating has significant impact in terms of extreme weather events, rise in sea water levels with resultant flooding of low lying coastal areas. By slowing this rate of rise, onset of such events can be delayed and even averted. These concepts will now be elaborated and presented, although preferred embodiments have been depicted and described in detail herein, it will be apparent to those skilled in the relevant art that various modifications, additions, Substitutions and the like can be made without departing from the spirit of the invention and these are therefore considered to be within the scope of the invention as defined herein below.
[0068] In one embodiment, shown in
[0069] In
[0070] The energy from 201, 202, 203 and 204 can be pooled and shared across multiple machineries and circuits, these machineries include horizontal pumps 205, that are used to pump water in horizontal direction to create, enhance or attenuate water currents 210 or deflect naturally occurring such as Gulf Stream 211 and these could be placed at varying ocean depths to create a desired profile of currents. These currents can be used to force mixing for modifying surface temperatures or changing the geographical spread of the water as required.
[0071] The energy can be also used for vertical pumps 206, which pump water in vertical direction to create flow vertically for purpose of vertical mixing in terms of upwelling or down-welling 212, and churning 213 or redistributing matter and by doing this moving cooler deep water to surface to reduce the surface temperature increase the surface density and salinity, in effect changing the profiles 103, 104, 107 and 108 as required.
[0072] Another use of energy shown in
[0073] Another use of energy is to change the salinity profile 107 using devices which reduce the ionic concentration with osmotic pumps 208 to remove ions or adding salts or ionic chemicals to modify the salinity 216 as desired. Since naturally the surface salinity is low, stratifying the surface waters, addition of salts on surface will increase the density of the warm waters sinking them to promote better mixing, conversely the salt can be extracted from deeper water reducing the density at lower depths and causing the upper waters to be more saline and denser thus promoting vertical mixing.
[0074] Another use of energy is to change the humidity 217 at the surface of ocean by using machineries such as mister (misting devices) or de-humidifiers 209. These devices by modifying the immediate vicinity of humidity can cause extra interaction between the ocean and the atmosphere especially layers of air right above the ocean and modify the water content as the surface wind rises upward. These allow the coupling of energy between air and ocean to be engineered as required.
[0075] In
[0076] The energy from 218, 219, 220 and 221 can be pooled and shared across multiple machineries and circuits, these machineries include horizontal pumps 222, that are used to pump water in horizontal direction to create, enhance or attenuate water currents 227 or deflect naturally occurring such as Gulf Stream 228 and these could be placed at varying ocean depths to create a desired profile of currents. These currents can be used to force mixing for modifying surface temperatures or changing the geographical spread of the water as required.
[0077] The energy can be also used for vertical pumps 223, which pump water in vertical direction to create flow vertically for purpose of vertical mixing in terms of upwelling or down-welling 229, and churning 230 or redistributing matter and by doing this moving cooler deep water to surface to reduce the surface temperature increase the surface density and salinity, in effect changing the profiles 103, 104, 107 and 108 as required.
[0078] Another use of work done as shown in
[0079] Another use of work done is to change the salinity profile 107 using devices that reduce the ionic concentration with osmotic pumps 225 to remove ions or adding salts or ionic chemicals to modify the salinity 223 as desired. Since naturally the surface salinity is low, stratifying the surface waters, addition of salts on surface will increase the density of the warm waters sinking them to promote better mixing, conversely the salt can be extracted from deeper water reducing the density at lower depths and causing the upper waters to be more saline and denser thus promoting vertical mixing.
[0080] Another use of energy is to change the humidity 234 at the surface of ocean by using machineries such as mister (misting devices) or de-humidifiers 226. These devices by modifying the immediate vicinity of humidity can cause extra interaction between the ocean and the atmosphere especially layers of air right above the ocean and modify the water content as the surface wind rises upward. These allow the coupling of energy between air and ocean to be engineered as required.
[0081] In one embodiment, the sources and machineries are all located in a physical co-located cluster and structure referred as Control Station, a functional embodiment of that 300 is shown in
[0082] These power sources 301 through 306 are used to drive machineries and systems 307, consisting of pumps 308, fans 309, heat pumps 310, radiative cooler 311, humidity control devices 312, and gas exchangers 313. Pumps 308 are used to move water around to modify the thermal, salinity and density profiles or water currents. The fans 309 are turbines used in reverse to drive changes in wind patterns and affect the mixing of atmosphere and its interaction with ocean. Heat pumps 310 are used to move mainly heat from one location to another to modify the temperature profiles vertically or horizontally. Radiative coolers 311 are devices that take electrical energy and emit in infrared around 9 micrometer wavelengths and thus cool by radiating the extra energy to outer space. This is because by emitting in the atmospheric absorption window range of wavelength between 8 um to 10 um no absorption takes place in the atmosphere and the radiation is directly sent to outer space which is lot more efficient as a cooler. Humidity control devices 312 such as misting and dehumidifying machines change the relative humidity in the proximity and thus impact the interaction between the ocean and atmosphere, this can be used to modify precipitation patterns and control air temperatures and winds. Similarly Gas exchangers 313, can be used to change the amount of gas interacting with oceans affecting the coupling of energy and nature and concentrations of gases and nutrients in the ocean impacting the biosphere. The control station 300 can be used in the manner described in
[0083] Another key set of systems in the Control station 300 are the communication and computing systems 314. These systems are used to collect the data and establish communications with a distributed information system via satellite communications 315 or wireless or wired sensor network 316 and connected with other stations using undersea optical or copper cables and other means of connectivity. In addition by using onboard computers 318 and data storage 319 the data collected can be validated and cross checked before and after communication and complete information processing done 320.
[0084] In another embodiment, the control station are engineered to be self sufficient to deliver the functional requirements laid out in 300. In order to be able to work at a rate high enough to influence the local weather, or the trend and long term climate, the control stations have to do meaningful work at a scale large enough and over durations of days and months, thus the energy generation systems have to provide large amount of energy. These control station are proposed to be powered by renewable energy that can be stored using batteries, so that they can operate for decades altogether, and to ensure that energy is not a limitation for type and quantity of the work to be done. The specific renewable energy sources can be combination of Wind, Solar, waves, or Oceanic currents, depending on location and time of the day or year. The primary source of power will be wind, as technology for offshore windmills is maturing and costs are coming down to make it viable. In addition, winds are present near the coasts and in the open seas, the wind power across the oceans averages around 500 W/m.sup.2, however depending on the location, geography and the season. Generation at a site can be predictably estimated and the historical information is available and in most regions the energy from wind is plentiful for our purpose. However, there are areas where winds are not strong, one such area is in the sub tropical Pacific: the infamous windless doldrums. Stations located in these specific areas are designed to not depend on wind instead they use solar power in combination with oceanic current and or waves. In order to have reasonable and significant impact and to cause the required amount of perturbation in the local conditions, it is imperative to have significant amount of power. On the other hand, the engineering systems size and design should be consistent with prevailing capabilities and system sizes that are commercially available. Recent designs of offshore wind platforms are targeted around 5 to 10 MW. One embodiment of the station uses sizes of around 5 to 10 MW in size, so that the design of turbine and platform can be similar. With these two considerations, the systems should be sized to be around 5 to 10 MW driven by renewable energy sources. To generate 10 MW using winds along the coast range there is sufficient power across the globe (500 W/m.sup.2), albeit it depends on the seasons. The data shows that in the open oceans winds are strong enough to generate most of required power from them. These winds can be intermittent and do vary significantly during the day, with differences in ocean and air temperatures driving local changes between day and night, these effects are strongly modulated with proximity to land masses, yet larger changes are seen due to seasons. In terms of the size of the turbine itself, larger sizes allow reduction in cost of the system and also its operational cost with lower fraction spent on overheads such as superstructure to hold the turbines and also circuits for power evacuation or station control. Industry capability trends the wind turbines of 10 MW will be possible in next decade and these can be with 50 meters to 150 meter high masts and diameters of 50 meter to 150 meter. Depending on the depth of waters different types of the platform or pedestal for the turbines are designed and used. By using large 10 MW station the cost of these structures is better amortized for the station.
[0085] Solar power generation is possible across most of the regions, except perhaps the Arctic and Antarctic; where snow cover is a concern, however solar is key where winds are low (doldrum latitudes). But, solar panels require large areas, for instance a 1 MW plant capacity requires minimally 6000 square meters of area. This may be possible by covering all available surfaces of station buildings and turbine towers, or by building a floating array on a pontoon or platform of say 80 m80 m. For larger capacities it will be necessary to use large fields of floating arrays. Since solar power varies with time of the day, the power generated can be best used in conjunction with storage, which will allow it to be dispatched when needed and used optimally.
[0086] The Gulf Stream, is a strong and nearly constant ocean current, this current and the energy in it can be used to drive underwater turbines, giving continual generation. The tapping off of the energy from the current can also be used to slow it down and it doing so deflects them from natural course in a controllable manner. This method is also itself be a way to engineer a controlled method to change the local weather and current energetics. For instance the ocean current turbines can be placed off the coast of North Carolina where the Gulf Stream deviates away from the east coast. By ensuring the current flows closer to the coast or away from it the local weather or long-term climate can be influenced. The Gulf Stream has nearly 90 GW of kinetic energy in the current and this is extending along 1800 km near the coast, extracting this kinetic energy and changing it's nature to modify the currents, humidity, air and water temperatures or winds is a powerful method possible.
[0087] Embodiments of the invention mainly use renewable energy sources to drive machines, pumps and heat pumps. Electricity is generated using wind turbines, solar panels and/or ocean current turbines. The wind turbines and solar power systems are built on floating pontoons structures, rigs or manmade islands, by combining the counteracting mechanical requirements of solar and wind structures for overall balance and cost optimization. One embodiment of the structure for the ocean based control station 400 is shown in
[0088] One embodiment of the windmill is shown in
[0089] In conventional design the windmill tower experiences the wind forces acting on the top of the tower and this force creates torque to topple the tower, this torque is counteracted by rigid support at the bottom of the tower, which is typically done with solid connection and ballasting into ground structure. In the control station designed for oceans, direct solid ground structures are deep on ocean floor which are connected using submerged pedestal structures that can be economically viable when the depths range from tens of meters to perhaps hundreds of meters deep.

[0094] Embodiments of the invention may achieve a surface sea temperature (SST) is a key factor determining the local weather and in general short and long-term climatic conditions. The way to control SST and mixing of Oceans, which may assist to slow down the immediate temperature rise and climatic change.
[0095] As shown in
[0096] A simple apparatus to move heat down into ocean depths would be a passive heat exchanger designed to take heat from the surface of the ocean into lower depths based solely on thermodynamics and heat flow. This could consist of heat exchanger tube mesh or net near the top 10 m of surface and a solid rod or piped connection to another heat exchanger mesh at depths around 1000 meters. These two meshes would be connected via metallic cylinders or tubes that conduct heat from the hotter surface down to the colder realms of lower depths. The heat exchanger would conduct the heat from surface to the lower depths and reduce the temperature on surface by doing so. Calculations are shown here for 1 square kilometer of Open ocean area. Taking the case of the transfer of heat from ocean surface down to depths of 1000 m where the temperatures are lesser than 5 C. The radiation incident on equatorial surface is 1000 W/sq-m during daylight but averages to around 340 W/sq-m over the globe (or in 24 hours at a location). For one square kilometer this translates to 340 MW of incident radiation, we now assume that roughly 10% of it is absorbed by Ocean surface. That means we have to move away roughly 34 MW of heat away from the surface to avoid heating. If we were to design mesh heat exchangers at the top and bottom, and used thermal conduction to connect them across 1000 m depth, the required cross-sectional area for Copper tubing would be 4.5 sq-km, that is 4.5 times the total area available. If we used Monel, an alloy that will avoid corrosion in the seawater, the required area is 65 sq km! Clearly the simple metal tubing connected heat exchanger will not even work for conducting 10% of the incident heat. Conversely assuming even the unrealistic design of using the full square-kilometer of area we can theoretically only conduct perhaps 2% of the heat with Copper and only 0.15% with Monel.

[0099] In order to be able to conduct the 34 MW of heat given the latent heat of vaporization as 2440 kJ/kg, we need to evaporate water at the rate of 13.9 kg/s. The required water flow at 25 C. is about 15 liters/s or 911 standard liters per minute. For the water to boil at 25 C., it has to be under vacuum of lesser than 3000 Pascals, which is achieved by using vacuum pump 703 that moves the vapors towards the cold end through pipes 704, using second stage pump 705 which pushes the fluid through one way valve 706, the where the vapors are compressed and condensed back into liquid at temperatures lesser than 5 C. The evaporation-condensation cycle is done in a closed loop system like shown in
[0100] As shown in
[0101] In another embodiment, regular information is processed from the Control sensors. This is shown in
[0102] In a further embodiment, the array of control stations are spread across the globe and the functioning of their machines and pumps coordinated across long distances. By using an array of large number of pumps or devices the system can affect large areas while each device distributed in the array is impacting practical size of power (5 to 20 MW) or area (one to ten square kilometer), as shown in
[0103] In yet another embodiment, the global placement of the machines in the array on the open seas is designed, so as to be most efficacious and this is done by using gridding patterns, densities and algorithms as developed in numerical computing
[0104] In another embodiment since the interest is to collect relevant data especially in areas where fast changes are a-priori known to occur, the grid design can be denser near these locations, much like triangular grid designs used in setting up 3-D computer numerical solutions, wherein the grid get optimized to extract maximal information.
[0105] In another embodiment in addition to control stations arranged as per
[0106] In another embodiment shown in
[0107] For instance the large amount of raw data collected is processed and synthesized into a useable form of four dimensional geospatial Information System (4D GIS) showing evolution with time of global variables of interest.
[0108] For this to be meaningful key summary statistics are computed and available enabling easy visualization and analysis. The synthesized data is input to the Modeling 1303, which uses enhanced Numerical Weather Prediction 13031 including couple Ocean-Atmosphere global 130311 modeling with the key model parameters extracted 130312 from past epochs and Global climate 130313 predicted.
[0109] Modeling of the system and the behavior of the Global climate is the heart of this system, which is based on enhanced Numerical Weather Prediction (NWP). NWP captures state of art models of Global climate and weather systems with sophisticated physical models for interaction between Ocean and Atmosphere via parameters such as wind velocity, humidity, pressure, ocean and atmosphere coupling etc. The models are parameterized with coefficients such as energy interaction terms that can be varied to fit the observed physical phenomena. One embodiment consists of improving Numerical Weather Prediction by sharing extensive fine-grained data from all the stations, that is combined in a hierarchical fashion using local data and its time evolution and summing it for wider area of model. There are a number of global climate modeling and prediction tools in use today, in one aspect of this invention, these NWP models are enhanced incorporating in to the system the concept of an array of control station designed to change local parameters so to controllably changer or engineer perturbation and forcing at the nodes and using the array, much larger areas. The NWP is used to reanalyze historical data 13032 with initial conditions input from past information 130321 and predictions of model are compared to actual evolution of the weather 130322, this process allows the calibration of the key parameters used in NWP 130323. Thus, the numerical modeling simulations use the data collection of wind, surface temperature over large areas to refine numerical weather prediction. These simulation models are then calibrated against historical and episodic data, and refined based on the derived fits. The modeling then is used to provide predictions 13033, which are calibrated with information at hand 130331. Since, Numerical Weather Prediction (NWP) is error prone due to importance of small errors accumulating during predictive simulations, as a result 4 Dimensional variation analyses are used in conjunction with ensemble simulations with adaptive observations to check on evolution of the most likely scenarios. The dense grid proposed here will enable better predictions and observations further improving the predictions. These predictions however still depend on the unfolding of natural processes, which are chaotic, and can vary the results significantly depending on interaction of multiple processes and factors. The predictions dictate the choice of forcing done using the Control Network 1304, that uses the Control Stations 13041 to modify local conditions 130411 and characterize the response 130412 in real time, this is done across a large area 13042 with coordinated network response 130421 to observe meso i.e. tens of kilometers and global scale changes 130422. The time evolution 13043 of the response is observed to separate the transient changes 130431 from the desired long-term trends 130432.
[0110] The prediction algorithms 1305 are then used with designed controlled perturbations deployed through the array of control stations. The algorithm contains information processing 13051 to ensure right set of targets are set for the future 130511, with the measurable impact quantified 130512 and feedback loop 130513 completed on the control stations with finer grained shorter term information to ensure actions are as desired. The impact of a control setting is characterized with historical and real-time learning and this is used to define the prediction system with Machine Learning so as to evolve the controls 130521 appropriately to induce the right amount of impact, also this learning is used to control and modify the prediction model 130522 itself using real settings on Control station and measuring the impact of physical control array settings. The results of predictions are then compared to the experimental observations that result from the forced perturbations in 1301, thus completing the information feedback loop for further refining the algorithms 1305.

[0115]
[0116] Conventional heat pumps can be operated using renewable generated electricity, to move heat out from colder region to the hotter areas. These heat pumps can be used to cool the water lapping on the underside of Arctic ice, keeping that portion stable and offsetting any tendency to melt due to higher water temperatures. The embodiment shows the use of plurality of renewable energy based control stations 400, with wind turbines on towers 407, blades 408 and 410 and nacelle 409 with stator and motors. These turbines collect energy from wind to run heat pumps that are used to cool the water lapping the underside of the ice-shelf, the heat pump consists of the surface heat exchanger tube network 701, extending and connected underneath the solar panel array structure 1509, 701 absorbs energy from the surface seawater reducing the surface sea temperature, this heat is used to evaporate a thermic fluid which is being pumped out through a pressure control valve 702 by a vacuum pump 703. The low pressure pump 703 is sucking out the thermic fluid from the heat exchanger 701 and causing fluid evaporation and removal of heat of evaporation from surface and thus moving the heat down through insulated piping 704 from where it is moved to the open and deeper ocean area 1501, using second stage pumping 705, that extracts the fluid and compresses it to higher pressure through the one way valve 706. The compressed thermic liquid condenses in the exchanger tube mesh 707 with extension shown as 1501, where the thermic fluid in heat exchanger is releasing its heat of condensation in the desired colder ocean depths, from where the condensed thermic fluid is pulled out by deep-water pumps 708 which pumps it to the top surface through insulated pipes 709 with flow control valve 710, extra thermic liquid is stored in reservoir 711, from where it is pumped using surface pumps 712 expanding the fluid volume into the heat exchanger tube mesh 701 where the low pressure leads to the evaporation of the liquid into gas and completing the closed loop for the thermic fluid. The heat extracted would be pushed out into deeper colder water currents. The cooling of the waters can be done with single renewable energy stations of 10 MW generating roughly 50 MWh energy per day, which would allow on the order of 100 MWh i.e. 3600 Mega-Joules or more of heat to be removed, this would save roughly 10 Tons of buttressing ice every day. Although this number may looks small, but it important to recognize the benefit of avoiding this calving leads to slowing down of the crevassing and calving process, slowing down and avoiding the melting of perhaps tens times larger amount of ice being pushed into the sea. With appropriate engineering specific to the coastal area a number of coordinated stations can potentially stave off melting of critical ice-shelves. In addition, the total northward ocean heat transport due to Atlantic meridional overturning circulation is estimated to be 500 GW, not all of this makes it way to the Arctic, also only the recent extra amount has to be addressed, which is today roughly 0.3% increase on an average (1 W/sq increase in 340 W/sq). Thus, the additional ocean heat content to address is roughly 2 GW! Use of the heat pump methods allows this to be controlled with lesser than 1 GW of work done by an array of renewable stations.
[0117] In another embodiment of the invention, the renewable energy powered 200 control stations 300 and 400, to engineer the interaction between ocean and atmosphere 500, along with extensive sensor based collection of rich data using network 800 and distributed data processing 900 are arrayed together as in 1000, with a complete learning system 1300 using enhanced NWP (Numerical Weather prediction) 1400 with simulated forcing to define control steps, are used to control the global climate and weather as shown in
[0118] The required size of these arrays can be estimated as follows, first we consider the Gulf Stream 1702 that flows along the East Coast of US, which transports near 30 Million cubic meters per second (30 sverdrups sv) near Florida Straits (and 150 sv near Newfoundland). Gulf Stream is typically 100 km wide with depths of 800 m to 1200 m and surface velocities lesser than 2.5 m/s, the average depth of the current consistent with the above data is therefore around 150 meters. To change temperature of one cubic meter by 1 C., requires 1.2 kWh, therefore to reduce the temperature of 30 Million Cubic meters by 1 C. requires 36 Million kWh, which is 36 GWh, since water is flowing at a rate of 30 sv, we require 130 TW of heat removal to reduce the surface temperatures by 1 C. Using a heat up will require between 30 to 60 TW of renewable energy power. Another approach is to pump the surface water down deeper and slow down the build up of the surface temperature. Recognizing that naturally the top layer thermocline ranges in depth from 50 m to 100 m, by pumping vertically this water the layer can be doubled and therefore the solar heating of the surface slowed by a significant factor of 2. The power required for this pumping this top 100 m is roughly 6 TW. However, since the effect of this pumping is to reduce the temperature build up over the season also since the impact need not be 1 C. as that is a large forcing, so the actual power can be even about 1 TW and still have significant impact on the overall temperature. For the El Nino regions 1701, the estimate of higher the normal temperatures is around 1 to 2 C. and the total warm water volume for the strongest El Nino years is approximately 210.sup.14 cubic meters, so the total heat content is around 510.sup.14 kWh, since this is accumulated over 3 to 4 years, this requires renewable energy sources of 10.sup.14 W or 100 TW. To move heat the down would require between 30 to 50 TW of renewable powered control stations. The El Nino process is of recharge-discharge and is centered on a build up of ocean heat in the tropical western Pacific in the cool phase, and then the heat is moved across the Pacific and then polewards within the ocean during the El Nino phase. This process involves lateral and vertical redistribution of heat within the basin involving the energy buildup, redistribution and distribution of the total heat. These processes can be modified with critically placed intervention even of few TW level can be effective to prevent the build up to the critical point and to slow down or attenuate the magnitude. One aspect can be ensuring stable trade winds to ensure build up of heat in still waters is avoided, or ensuring more effective transfer of motion from wind to the sea surface.
