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.

Abstract: A method for computing and displaying a weather hazard threat level for a weather radar system of an aircraft includes receiving weather radar returns from a radar antenna of the weather radar system. The weather radar returns include at least one of horizontal scans and vertical scans. Radar reflectivity may be determined from the weather radar returns, and, for at least one of the horizontal scan data and the vertical scan data, areas of radar reflectivity and a temperature associated with the areas of radar reflectivity may be determined. A lightning flash rate may be estimated using the radar reflectivity, areas of radar reflectivity, and temperature associated with the areas of radar reflectivity. Weather radar information may then be displayed, wherein the weather radar information is adjusted on the display based on the lightning flash rate.
