Abstract

The invention provides a typhoon wind speed inversion method and device, electronic equipment and a storage medium, and relates to the technical field of remote sensing image processing, and the method specifically comprises the steps: obtaining a first remote sensing image of a second marine B satellite microwave radiometer and a second remote sensing image of a microwave scatterometer at the same time; obtaining the brightness temperature of each frequency band of each pixel of the typhoon area to be inverted from the first remote sensing image, and obtaining the backscattering coefficient of each pixel of the typhoon area to be inverted from the second remote sensing image; and processing the brightness temperature of each frequency band and the backscattering coefficient of the same pixel of the typhoon area to be inverted by using a typhoon wind speed inversion model which is trained in advance to obtain the wind speed of each pixel of the typhoon area to be inverted. The typhoon wind speed inversion precision can be improved.

Description

technical field [0001] The present application relates to the technical field of remote sensing image processing, in particular to a typhoon wind speed retrieval method, device, electronic equipment and storage medium. Background technique [0002] A typhoon is a strong cyclonic eddy that occurs on the tropical ocean, and is a powerful and deep weather system. As one of the most destructive natural phenomena on the earth, the severity of the disaster it causes is extremely high, and it 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 a tsunami, which seriously endangers 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 over a large area fr...
