Abstract

In order to improve the accuracy and timeliness of lightning prewarning, a real-time lightning warning system is established based on the monitoring information of atmospheric electric field, lightning location and weather radar. Firstly, a lightning warning model was built according to the changing rule of atmospheric electric field. Secondly, the warning algorithms of these three kinds of data were designed separately, and the reasonable warning thresholds were selected. Finally, lightning warning information was sent accurately to the customers who were located in the warning grids through targeted sending technology.

RESULTS show that the integrated model of multiple data with the reasonable setting of warning threshold, the fully automatic operation of the system and the targeted sending technology of information can improve the effect of lightning prewarning, it is also find that the systems is able to send out lightning warning 5-30 minutes ahead through several tests of thunderstorm process. © 2019 China Safety Science Journal.
