A system and method for downlinking weather data, generated by existing weather and data sensors, to a ground station. The ground station utilizes data from multiple aircraft to form refined weather information, and uplinks the refined weather information to the aircraft. The refined weather information is stored at the aircraft and picture generating equipment, such as an existing onboard ground proximity terrain or weather radar picture and symbol generator, generates pictorial information depicting weather. The pictorial information is displayed, for example by an existing EFIS or weather radar display, in the form of polygons.

1. An aircraft-based weather information sharing and display device comprising:at a ground station:reception equipment for receiving weather parameters from a plurality of weather-sensing sources;processing equipment for generating a refined weather information report, based on said received weather parameters, using data compression techniques to reduce the size of said weather information report; andtransmission equipment for uplinking said refined data-compressed weather information report to a plurality of aircraft; andat an aircraft:standard weather information gathering equipment for detecting local weather parameters characterizing a weather condition in the vicinity of the aircraft;transmission equipment for transmitting said local weather parameters to said ground station;reception equipment for receiving said refined data-compressed weather information report uplinked by said ground station;storage equipment for storing received said weather information report and said detected local weather parameters;picture generating equipment for generating symbolic pictorial information based on the received refined weather information and said detected local weather parameters; andweather information display equipment, coupled to the picture generating equipment, for displaying pictorial polygons indicating the dynamic behavior of said weather condition and a future prediction of the behavior of said weather condition,wherein said displayed pictorial polygons of said dynamic behavior and said future prediction presents an intensity indication of said weather conditions, the intensity indication is unrelated to direction of travel. 2. The device of claim 1 wherein said pictorial polygons display the predicted dynamic behavior of said weather conditions. 3. The device of claim 1 wherein said dynamic behavior comprises the movement of said weather conditions. 4. The device of claim 1, wherein said data compression technique further comprises a weather parameter rate such that the frequency of said uplinking of said weather information report is reduced. 5. The device of claim 1, wherein the ground station further comprises a broadcast scheduling equipment that tailors said weather information report to each of said plurality of aircraft, based on a position of each of said aircraft, such that the length of said weather information report is reduced. 6. The device of claim 1, wherein said data compression technique comprises extracting salient features of said refined weather information, and inputting said salient features into said weather information report. 7. The device of claim 1, wherein said data compression technique comprises formatting said weather information report in an Aviation Weather Information Network format. 8. The device of claim 1, further comprising equipment on said aircraft that generates an alert to the aircraft pilot when said processing equipment detects a dangerous weather phenomenon. 9. The device of claim 1 wherein the future prediction includes a prediction of one or more of strength, position, speed, direction of travel, size, rate of rain, or turbulence level. 10. A method for displaying the dynamic behavior of a weather condition on an aircraft display comprising the steps of:receiving a refined data-compressed weather information report uplinked by a weather ground station;decompressing said refined data-compressed weather information report;storing said received refined decompressed weather information report;generating symbolic pictorial information based on said received weather information report utilizing standard picture generating equipment already installed on the aircraft; anddisplaying pictorial polygons indicating the dynamic behavior of said weather condition and a future prediction of the behavior of said weather condition using EFIS or weather radar display equipment already installed on the aircraft,wherein said displayed pictorial polygons of said dynamic behavior and said futur e prediction presents an intensity indication of said weather conditions, the intensity indication is unrelated to direction of travel. 11. The method of claim 10 wherein said step of displaying comprises:displaying the area surrounding the aircraft's flight path; anddisplaying polygons representing the predicted dynamic behavior of significant weather formations, based on said uplinked weather information, relative to said flight path such that a pilot may navigate away from dangerous weather. 12. The method of claim 10 wherein said step of displaying comprises overlaying said pictorial symbols over a locally-received weather radar return display. 13. The method of claim 10 wherein the future prediction includes a prediction of one or more of strength, position, speed, direction of travel, size, rate of rain, or turbulence level.
