On this basis, typhoons can generally be divided into typhoons with eyes and typhoons without eyes. The temperature of the center of typhoons with eyes is significantly higher than that of the surrounding cloud walls, so an obvious eye can be observed on s

Abstract

The invention provides a typhoon positioning detection method based on a Himawari meteorological satellite. A meteorological satellite cloud atlas in 0.64-micron short-wave infrared window frequency band is adopted, the detection precision is higher, and the instantaneity is good; since the form of the typhoon is highly irregular at the beginning and the end of the typhoon, a detected center location and a CMA optimal path are large in deviation; and when the typhoon forms obvious eye of wind or is at a mature stage, the detection method has high accuracy on the centralized positioning of thetyphoon.

Description

technical field [0001] The invention relates to the field of meteorological nowcasting, in particular to a typhoon positioning and detection method based on sunflower meteorological satellites. Background technique [0002] In my country's coastal areas, almost every summer and autumn are more or less attacked by typhoons, and the loss of life and property suffered is not small. Therefore, we must take defensive measures before the typhoon comes to reduce the loss of life and property caused by the typhoon. [0003] Typhoon detection is an extremely important and complex subject. The main problem is to determine the center of the typhoon. In the early stage of typhoon formation, the shape is extremely irregular, and the center position is difficult to determine. After reaching the mature stage, it will appear in a vortex shape, and there are obvious spiral cloud belts around it. On this basis, typhoons can generally be divided into typhoons with eyes and typhoons without e...
