Abstract

This application provides a typhoon wind speed inversion method, device, electronic equipment, and storage medium, which relate to the technical field of remote sensing image processing, specifically: simultaneously acquire the first remote sensing image of the Haiyang No. 2 B satellite microwave radiometer and the second image of the microwave scatterometer. Remote sensing image: Obtain the brightness temperature of each frequency band of each pixel in the typhoon area to be retrieved from the first remote sensing image, and obtain the backscatter coefficient of each pixel in the typhoon area to be retrieved from the second remote sensing image; use the pre-trained typhoon wind speed The inversion model processes the brightness temperature and backscatter coefficient of each frequency band of the same pixel in the typhoon area to be inverted to obtain the wind speed of each pixel in the typhoon area to be inverted. The application can improve the typhoon wind speed retrieval accuracy.

Description

technical field [0001] The present application relates to the technical field of remote sensing image processing, and in particular to a typhoon wind speed inversion method, device, electronic device and storage medium. Background technique [0002] A typhoon is a strong cyclonic eddy that occurs over the tropical ocean and is a powerful and deep weather system. As one of the most destructive natural phenomena on the earth, the seriousness of the disasters caused by it is extremely strong and has super destructive power. When a typhoon occurs, it is often accompanied by strong winds, huge waves, heavy rainfall, storm surges, etc., and sometimes can cause tsunamis, which seriously endanger people's lives. [0003] The rapid development of satellite remote sensing technology has made it possible to observe typhoons in vast sea areas. Meteorological satellites have wide coverage, large imaging area and high time resolution, and can be used to monitor typhoons in large areas f...
