Abstract

The application relates to a lightning forecasting method and system. The method comprises the steps of reading the latest electric field station observation data and radar observation data of an electric field station, and establishing a lightning proximity prediction model according to the electric field station observation data and the radar observation data; the establishing of the lightning proximity prediction model comprises the following steps: step a: setting an electric field amplitude threshold and an electric field difference threshold; step b: judging whether the read electric field station observation data reaches the set electric field amplitude threshold or the electric field difference threshold, and if the electric field station observation data reaches the set electric field amplitude threshold or the electric field difference threshold, performing step c; step c: determining whether the radar observation data before the current time reaches the preset threshold, ifthe radar observation data reaches the preset threshold, performing step d; and step d: generating a lightning warning graphic product and issuing lightning warning. The application realizes the beforehand release of thunderstorm early warning, and raises the capability and level of lightning forecast.

Description

technical field [0001] The application belongs to the technical field of meteorological services, and in particular relates to a lightning forecasting method and system. Background technique [0002] Lightning is a weather phenomenon in which discharge occurs between clouds or between clouds and ground in cumulonimbus clouds. It has the characteristics of transient high current, high voltage and strong electromagnetic radiation. It is often accompanied by strong winds, heavy rain, hail and even tornadoes. It is a serious meteorological phenomenon. As one of the disasters, as early as the end of the last century, it was listed by the United Nations as "one of the ten most serious natural disasters", and it is also called "a major public hazard in the electronic information age". [0003] With the rapid development of our country's economy and the improvement of people's living standards, the increasing number of high-rise buildings and the wide application of various electron...
