摘要:

支持向量机(Support Vector Machine、简称SVM)方法是近年发展起来的一种新的统计学习理论方法,本文通过对这一方法的学习,总结陇东主要降雹的环流形势特点,利用这一新方法对冰雹分类预报进行了探讨,经检验,效果较好。并与传统的天气分型后制作预报模式进行了比较,验证了SVM方法不需要进行天气分型,这样总样本数多,建立的预报模型效果好。这为基层台站制作天气预报模式提供了一种新方法和新思路。

关键词: 支持向量机, 冰雹, 环流特征, 预报模式

Abstract:

The support vector machine(SVM) is a new statistical study theory method which developed in recent years,  by using this method in
hail in the method is this paper',  We analyzed  the classific;ation prediction of hail weather based on summarizing the circulation(harac;teristic;s of hail in east region of Cansu provinc;e} and(ompared with traditional forecast under different weather types.It is confirmed that SVM method is not need to classify weather types and the effect of forecast model being established is better on many samples. This has provided new method and idea for hasin stations nn weather forecast.

Key words: support vector machine, hail, (irc;ulationcharac, teristic, forecast model
