Abstract
Electromagnetic radiation from lightning is detected at a ground station which is part of a cellular network of stations; a computer determines a position of a thunderstorm associated with the lightning, then compiles and stores the storm location data. A user aircraft transmits, via cellular telephone equipment or direct radio link, a request for information together with a user identification number. After validation of the user number weather data is transmitted to the aircraft where a microcomputer processes the weather data to correct for the aircraft's position and heading, then displays storm locations relative to the aircraft. The display may incorporate radar data and satellite photographs of cloud formations. In-flight weather notices are transmitted in addition to the storm location data.
