A lightning forecast method and system

Abstract

The present application relates to a lightning forecasting method and system. The method includes: reading the latest electric field station data and radar observation data of the electric field site, and establishing a lightning nowcasting model according to the electric field station data and radar observation data; the establishment of the lightning nowcasting model includes the following steps: step a : Set the electric field amplitude threshold and electric field difference threshold; step b: judge whether the read electric field station data reaches the set electric field amplitude threshold or electric field difference threshold, if the electric field station data reaches the set electric field amplitude threshold or the electric field difference threshold, execute step c; step c: judge whether the radar observation data before the current moment reaches the preset threshold, if the radar observation data reaches the preset threshold, execute step d; step d: generate lightning warning graphic products and send out Thunder warning. The application realizes the early release of thunderstorm weather warning, and improves the ability and level of thunderstorm forecast and warning.

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...

Problems solved by technology

The occurrence of thunder and lightning is often closely related to strong convective weather, and most of the occurrence of strong convective weather is powered by the movement and changes of various small and medium-scale weather systems, usually only locally , the life history of the generated lightning is also short

Relying only on observation equipment, it is difficult to forecast lightning in advance, and it is difficult to meet the needs of citizens and various industries for fine lightning forecast and early warning services, thus affecting the service effect
