Problems solved by technology
[0004] In the research of extreme weather such as Typhoon Maisa and Typhoon Meihua, the inventor found that the typhoon wind speed has an inseparable relationship with gravity waves. However, in the prior art, there are few studies on the relationship between typhoon wind speed and gravity waves. There is no effective method to predict typhoon wind speed using gravity wave parameters

Description
technical field [0001] The invention relates to a prediction method in the field of meteorology, in particular to a method for predicting typhoon wind speed by using stratospheric gravity waves. Background technique [0002] The stratosphere, also known as the stratosphere, is the area between the troposphere and the middle layer. It is named because the air flow is mainly horizontal and there is little turbulence. The main feature of the temperature distribution is that the bottom is cold and the top is hot. The coldest area is the At the junction of the tropopause, the temperature increases with altitude. In recent years, with the development of remote sensing technology and satellite technology, stratospheric observation technology has been greatly developed. Lidar can obtain local atmospheric parameters with high temporal and spatial resolution. Limb detection technology and occultation technology have realized global The observations in the stratosphere region provide ...
