摘要
作者在亚洲自然天气区域的基础上,提出可用一条特征等高线来表征中纬度西风场特征的观点,进而提出一种双候相似相关的中期降水客观预报方法.经1988—1989年两年使用结果表明.它可以提高中期降水预报的能力.
In this paper, the authors propose that in the Asia natural synopitic region, features of the middle latitude westerly field may be expressed by a characteristic isohypse. Then they have developed a method of objective forecast for mid-range precipitation using the double pentad similarity and correlation. The results of applying this method in 1988-1989 show that it is possible to increase capability for the mid- range rainfall forecast.
