Abstract: A convective weather graphic element generator system generates graphic elements associated with severe convective weather for presentation on a display on an aircraft. An exemplary system employs a weather radar and a processing system. The processing system determines a value associated with the detected convective weather based on the received weather radar returns detected by the weather radar, compares the value associated with the detected convective weather with a threshold, and generates a graphic element for a region of airspace when the value associated with the detected convective weather exceeds the threshold. The display is configured to concurrently present the weather reflectivity information generated by the weather radar and the graphic element associated with the convective weather, wherein portions of both the presented graphic element and the presented weather reflectivity information of the corresponding area are concurrently visible on the display.

An exemplary embodiment receives weather information from a weather radar system on board a remote aircraft, processes the received weather information into weather radar image information that is displayable on at least a display, processes the weather radar image information into a reduced size dataset, and communicates the reduced size dataset to an installation aircraft over the low bandwidth communication channel, wherein the low bandwidth communication channel is generated by a low bandwidth communication transceiver on board the remote aircraft.

Abstract: Exemplary methods and systems provide for processing weather data received from a weather radar system. An exemplary embodiment receives radar reflectivity data, decomposes the received radar reflectivity data into multiple adaptive Gaussian component functions, selects at least one parameter from the decomposed Gaussian component functions, generates the compressed weather radar display data based on the at least one selected parameter, and communicates the weather radar display data from the craft.

Abstract: A weather radar system for improving output of potential lightning and hail weather conditions. An exemplary system includes a processor that receives and stores the weather radar reflectivity values into a three-dimensional buffer, receives an outside air temperature value, and determines freezing level based on the received outside air temperature value. The processor generates lightning icon(s) when a reflectivity value stored at cell(s) of the three-dimensional buffer above determined freezing level is greater than a first threshold amount. Also, the processor adds 1.6 km to the determined freezing level and generates hail icon(s) when a reflectivity value stored at cell(s) at the determined freezing level plus 1.6 km are greater than a second threshold amount. The display device displays the hail and lightning icons when an altitude value that corresponds to the cells associated with the generated lightning icons has been selected for display.
