An aircraft weather radar system can include an electronic display, a radar antenna for receiving radar returns, and an electronic processor. The electronic processor can be configured to determine an existence of potential wind shear activity using the radar returns and cause the electronic display to provide an indication of the potential wind shear activity. The potential wind shear activity is different than a wind shear condition associated with a predictive wind shear icon for a wind shear event.

A weather radar control system includes a processor configured to acquire first weather data for a first area extending from an aircraft from a weather radar system onboard the aircraft. The first weather data includes a first location of a weather event in the first area. The processor is further configured to receive second weather data for a second area with respect to the aircraft via the communication system from an external location where the second weather data includes a second location of a weather event in the second area, and correlate the first weather data and the second weather data. The processor is further configured to generate display data for display based on the correlated weather data where the display data is for a display area at least partially defined by the first and second areas, and provide the display data to a display system onboard the aircraft.

This disclosure is directed to methods, devices, and systems for generating a weather radar output with bright band suppression. In one example, a method includes determining, for each of several portions of a vertical column from a weather radar signal, a reflectivity range selected from a highest reflectivity range and one or more lower reflectivity ranges. The method further includes determining, in response to determining that portions of the vertical column are in the highest reflectivity range, whether a combination of the reflectivity ranges of the portions of the vertical column meet criteria indicative of high-reflectivity stratiform weather. The method further includes generating, in response to determining that the combination of the reflectivity ranges of the portions of the vertical column meet the criteria indicative of high-reflectivity stratiform weather, a weather radar output that indicates each of the portions of the vertical column as associated with one of the lower reflectivity ranges.
