Method, device and storage medium for lightning early warning based on lightning data mining

Abstract

The invention discloses a method and device for realizing thunder and lightning early warning based on thunder and lightning data mining and a storage medium. The method comprises the following steps:S10) analyzing atmospheric electric field intensity and radar echo, and when meeting preset conditions, starting a thunder and lightning warning process; S20) collecting satellite cloud picture dataand thunder and lightning location data, combining the satellite cloud picture data and the thunder and lightning location data and carrying out judgment and correction, and carrying out clustering analysis on the thunder and lightning data to obtain moving speed and direction of thunderstorm clouds; S30) according to the obtained thunderstorm cloud distribution, calculating moving speed and direction of the thunderstorm clouds through a linear regression method, and predicting the location and quantity of thunder and lightning at the next moment; and S40) dividing the area into different grids, and carrying out corresponding levels of thunder and lightning warning according to the predicated location and quantity of thunder and lightning. The thunder and lightning early warning method hasthe advantages of short warning time and high accuracy, reduces overall false alarm rate of a thunder and lightning detection network, improves thunder and lightning warning accuracy and reduces thunder and lightning early warning space accuracy.

Description

technical field [0001] The invention belongs to the technical field of lightning early warning, and in particular relates to a lightning early warning method, device and storage medium. Background technique [0002] With its strong current, scorching high temperature, violent shock wave and strong electromagnetic radiation and other physical effects, lightning can cause huge damage in an instant, resulting in property and casualties. In recent years, my country has gradually increased the construction of UHV transmission lines, and implemented a strong and smart grid strategy with UHV power grids as the core and coordinated development of power grids at all levels. It is also bigger. If the line fails, the power supply demand cannot be restored in time, which will bring huge losses to the national economy. [0003] Lightning phenomenon is still a natural phenomenon that human beings have not fully explained the mechanism and mastered the laws. It has the characteristics of h...

AI Technical Summary

Problems solved by technology

At present, the method of lightning early warning implemented by many units is to directly reflect the atmospheric electric field data detected by the ground electric field instrument, the lightning location data monitored by the lightning locator, the relevant data detected by the radar, and the data information obtained from the data center of the Meteorological Bureau. The early warning effect is not ideal
