摘要： 本文根据近38年(1951—1988年)海平面气压场与我国160个站降水的冬夏距平值,研究了季风降水与赤道东太平洋海温(SST)变化的关系,发现两者有联系的年占一定优势。季风降水与SST的关系虽非逐年对应,但SST异常对东亚季风气压场的年际变化及我国降水变化仍是一个不可忽视的影响因素。

Abstract: The ralationships between the monsoon rainfall and the sea-surface temperature (SST) in the Equatorial Eastern Pacific are examined based on the thirty-eight-year (1951-1988) data set of sea level pressure maps in the Northern Hemisphere and the rainfall of 160 stations over China in summer (June-August) and winter (Dec.-Feb.).The study shows predominance of the years, in which the monsoon rainfall does not in accordance with the SST year to year. However, the SST anomaly takes a role which can not be ignored in examining the interannual variability of monsoon pressure field over East Asia and the monsoon rainfall in China.

Key words: monsoon rainfall, E1 Nino, sea level pressure field
