摘要
利用遥相关对云南省雨季降水作中长期预报，采用不规则格点上的车贝雪夫多项式建立了印度洋海温场与云南省雨季降水场的预报方程。通过对１９９３年及１９９４年的预报检验，效果较理想。
In this paper, approaching the correlation between the Indian Ocean surface temperature and the rainfall of rainy season in Yunnan, using the materials from 1965 to 1992, with the calculation method of Chebyshev Polynomials in irregular grids, we set up a system of forecast equations between the Indian Ocean surface temperature field (20°S-20°N, 50°E-95°E) and rainfall field in Yunnan (20 meteorological stations). Through forecast test of the rainfall field in Yunnan in 1993 and 1994, the result is satisfactory.
