Abstract

The invention, which belongs to the technical field of typhoon intensity processing, especially relates to a method and system for carrying out processing on environment prediction factor data of a typhoon intensity. The method comprises: step a, selecting an environment prediction factor correlated with a typhoon intensity change, and calculating and extracting parameter data correlated with the environment prediction factor; and step b, carrying out standardization processing on the parameter data of the environment prediction factor and carrying out principal component analysis processing on the parameter data after the standardization processing, thereby obtaining new environment prediction factor parameter data. According to the invention, repeatability and inner links of all environment prediction factors are considered fully and are eliminated by using the principal component analysis method, so that the accuracy of the typhoon intensity prediction is improved. The method and system are suitable for sample data processing of various typhoon types.

Description

technical field [0001] The invention belongs to the technical field of typhoon intensity processing, and in particular relates to a method and system for processing typhoon intensity environment prediction factor data. Background technique [0002] Principal component analysis is a method of mathematical transformation. It hopes to use fewer variables to explain most of the variables in the original data, and convert many highly correlated variables in our hands into mutually independent or irrelevant variables. Usually, several new variables, which are less than the original variables and can explain most of the variables in the data, are selected, which are the so-called principal components, and are used to explain the comprehensive indicators of the data. It can be seen that principal component analysis is actually a dimensionality reduction method. It converts a given set of related variables into another set of unrelated variables through linear transformation, and th...
