摘要
提出一种对春季气温趋势分类的方法，用Чебышев多项式和 EOF展开方法，求出一组系数，并根据这些系数把春季气温趋势分为 5类。用上述方法明确地描述春季气温趋势的特征。更进一步从冬季 500hPa平均图中选取预报因子，对春季气温趋势作出预测。
A method to classify the tendency of temperature in spring is given here,by which the tendency of temperature in spring in Bayinguoleng Mongolia Autonomous Prefecture is divided into five categories after obtaining a series of coefficients by means ofЧебышев polynomials and EOF.Then,the tendency of temperature is predicted by selecting predicting factors from 500hPa monthly mean map in winter.
