摘要
利用不规则格点上的车贝雪夫多项式及逐步回归的计算方法，用云南省降水距平资料建立印度洋海温场与云南省雨季降水场的预报方程，并做了１９９６ 年及１９９７ 年雨季降水预报检验，效果较理想．
With the calulation method of Chebyshev Polynomials in irregular grids and stepwise regression,a system of forecast equations between the Indian Ocean surface temperature and the rainfall of rainy season in Yunnan with precipitation anomaly value in Yunnan is set up.Thraugh forecast test of the rainfall field in Yunnan in 1996 and 1997,the result is satisfactory.
