Severe convection weather early warning method, computer equipment and storage medium

Abstract

The invention belongs to the technical field of severe convection weather monitoring and provides a severe convection weather early warning method. The method comprises the following steps that: a GNSS receiver acquires CORS observation data and precise orbit / clock error correction information SSR, and processes the obtained data to obtain real-time troposphere total delay; and real-time troposphere dry delay is obtained according to real-time meteorological parameters. According to the severe convection weather early warning method of the invention, the satellite observation data and real-time meteorological parameters such as air pressure and temperature are received in real time through the GNSS receiver; dry and wet delay components of a troposphere are calculated in real time, and thechange of atmospheric water vapor content is obtained by means of inverse computation; a determined early warning threshold value is obtained according to the empirical model of the atmospheric watervapor content and actually measured precipitation in historical data; the purpose of monitoring severe convection weather in real time can be achieved according to the change of the atmospheric watervapor content and the real-time meteorological parameters. The method has the advantages of real-time detection and high precision.

Description

technical field [0001] The invention relates to the technical field of strong convective weather monitoring, in particular to a strong convective weather early warning method, computer equipment and a storage medium. Background technique [0002] Severe convective weather generally refers to short-term thunderstorms, strong winds, hail, and heavy precipitation. This type of weather is characterized by suddenness, strong locality, short life history, and severe disasters, which is a difficult point in weather forecasting. However, the frequency of its occurrence, the heavy casualties and property losses also make the study of this problem have important significance. [0003] At present, the forecast of severe convective weather is mainly realized by using automatic weather stations, radar technology, meteorological satellites and mesoscale numerical analysis. Since the 1990s, with the deployment of a new generation of Doppler velocity radars, the ability to detect severe co...

Problems solved by technology

[0006] Generally speaking, since the system that causes strong convective weather belongs to the small and medium-scale weather system, it is difficult to be accurately predicted by a single technique of the conventional meteorological observation network.
