Example Embodiment

[0030] In order to make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0031] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The first step is to obtain background data on the development and evolution of the typhoon. The embodiment takes 2008 "Phoenix" Typhoon as an example. Typhoon "Phoenix" formed at 06:00 on July 25, 2008 (UTC, the same below), and strengthened into a severe tropical storm east of Taiwan on the 26th, and became a typhoon at 09:00 on the 26th, and further strengthened at 12:00 on the 27th. A strong typhoon made landfall in Hualien, Taiwan at 22:30 on the 27th, and then continued to mo

Abstract

The invention relates to a technology for evaluating influence of meteorological factor change on a typhoon. The technology includes: acquiring the background field data of a typhoon development process; extracting concerned meteorological factor field data from the background field data; modifying the meteorological factor field data according to needs; using the modified meteorological factor field data to replace the meteorological factor field data before the modification to form modified new background field data; using a numerical model to carry out a typhoon simulation test based on theoriginal background field data and the modified background field data; analyzing a model output result, and quantitatively evaluating the influence of the meteorological factor change on typhoon intensity and path. The technology has the advantages that the evaluation of meteorological factors influencing typhoon development can be achieved, the technology can be used for evaluating the influencedegree of different meteorological factors on the typhoon development, the sensitivity of the typhoon development to the meteorological factors can be obtained, and theoretical and technological support is provided for the carrying out of an artificial typhoon influencing test from the perspective of engineering application.
