Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing typhoon path discrimination mainly relies on manual discrimination, which is difficult and affects the accuracy of the forecast, and to invent a typhoon path discrimination method based on historical data through a large number of calculations to obtain similar typhoon paths in history as the forecast path

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] Such as figure 1 shown.

[0040] A typhoon path discrimination method, it comprises the following steps:

[0041] First, use some basic information of typhoon and the buffer analysis technology and overlay analysis technology in GIS to complete the preliminary screening of typhoons with similar paths;

[0042] Secondly, calculate the similarity between the historical typhoon and the current typhoon from the two perspectives of type difference and value difference;

[0043] Finally, based on the similarity calculation results, the historical typhoon with the smallest similarity distance is the typhoon most similar to the current typhoon, thus completing the determination of the typhoon's similar path.

[0044] The specific judgment process is (such as figure 1 shown):

[0045] Step 1: Read the current typhoon track information.

[0046] The ...

Abstract

The invention discloses a method for discriminating a typhoon path. The problem of determination of a similar typhoon path is solved by algorithms of type differences and value differences among different typhoons and by using a buffer zone analysis technology and a superposition analysis technology in a global information system (GIS). Meanwhile, the method is based on the given typhoon basic data without addition of observation data and has highly strong service availability.

Description

technical field [0001] The invention relates to a meteorological technology, in particular to a typhoon path discrimination method in typhoon meteorological disasters, in particular to a typhoon path discrimination method using similarity method for path discrimination. Background technique [0002] As we all know, typhoon is one of the major meteorological disasters affecting our country. The comparative analysis of disasters of similar tropical cyclones (typhoons) is the focus of meteorological operations, and the determination of similar paths of typhoons is the difficulty in completing this operation. There is no good solution for judging typhoon similar paths, mainly relying on human eyes to judge, which has the disadvantages of subjectivity and complexity. Seriously affected the accuracy of typhoon track forecast. [0003] On the other hand, everything has its own rules to follow. If the historical information of typhoons can be used, it is of great significance for c...
