Real-time thunderstorm monitoring and early warning system

Abstract

The invention discloses a real-time thunderstorm monitoring and early warning system. The real-time thunderstorm monitoring system comprises at least three front-end lightning very low frequency / low frequency (VLF / LF) signal detection devices, a network transmission module and a thunderstorm monitoring and early warning monitoring center; the front-end lightning very low frequency / low frequency (VLF / LF) signal detection devices are all in communication connection with the thunderstorm monitoring and early warning monitoring center through the network transmission module. According to the real-time thunderstorm monitoring and early warning system, thunder and lightning phenomena are monitored in real time by arranging the very low frequency / low frequency (VLF / LF) signal detection devices onthe thunder and lightning monitoring site, monitoring results are sent to the thunderstorm monitoring and early warning monitoring center through the network transmission module, that is to say, by deploying the very low frequency / low frequency (VLF / LF) signal detection devices in a monitoring terminal area, monitoring and early warning on local severe thunderstorms can be achieved, potential thunder and lightning safety hazards can be eliminated, and severe convection activity monitoring on some areas difficult to be monitored by weather radars is complemented.

Description

technical field [0001] The invention belongs to the technical field of meteorological nowcasting, and relates to a real-time thunderstorm monitoring and early warning system. Background technique [0002] A thunderstorm is a violent discharge of thunder and lightning that occurs in cumulonimbus clouds. Because it is generally accompanied by showers, it is often referred to as thunderstorm, which is a sign of the strong development of cumulonimbus clouds. There are strong turbulence, icing, lightning, showers and strong winds in thunderstorms, and sometimes hail, tornadoes and downbursts, which are a serious threat to aircraft safety. [0003] In this paper, starting from the needs of aviation meteorological users for aviation meteorological services, aiming at improving the short-term nowcasting capabilities of regions and airports, and aiming at the difficulties in monitoring local severe convective thunderstorm systems, a set of thunderstorm lightning (severe convective a...

Problems solved by technology

[0004] The purpose of the present invention is to provide a real-time thunderstorm monitoring and early warning system. The thunderstorm real-time monitoring and early warning system realizes the real-time monitoring of lightning and transmits the results to the thunderstorm monitoring and early warning monitoring center, and can effectively improve the monitoring of the strong convection system in the terminal area. Timeliness reaches the level of continuous monitoring, expands the terminal’s monitoring range of severe thunderstorms to within 300km of the airport, and overall improves the monitoring and early warning capabilities of existing airport terminals for local severe thunderstorm systems. Realistic problems such as widespread weather effects and increasing flight delays are of great help, especially for those airports that have not been effectively covered by meteorological Doppler observations
