摘要
本文综述了近年来我国学者在海-气相互作用方面的研究成果,集中探讨了海-气相互作用对我国气候的若干影响。结果表明:（1）我国许多地区的降水和气温变化具有明显的准3.5年振荡周期,这一特征与赤道太平洋地区的海面温度也表现出强烈的准3.5年振荡现象有着密切的联系;（2）我国气温与南方涛动存在着遥相关的事实,可以作为早期识别埃尔-尼诺的信号;（3）热带太平洋海温异常影响到副热带高压强弱和位置的变化,是导致我国东部夏季旱涝和温度异常等灾害性气候的出现的主要原因;（4）ENSO当年全国登陆台风个数均少于常年。
After summarizing the research results of air-sea interaction obtained by the Chinese scientists in the recent years and discussing the influence of the air-sea interaction on China's climate this paper describes that:
( 1 ) The rainfall and temperature changes in many areas in China have an evident vibration period of about 3.5 years.This characteristic is closely
related with the strong 3.5-year vibration period happening in the tropical pacific ocean area caused by the sea surface temperature ( SST ) change.
( 2 ) The fact . that China's climate is remotely interrelated with the Southern Oscillation is considered as an early singal to identify El-Nino.
( 3 ) The abnormality of SST in tropical pacific ocean affects the strength and position change of the subtropical high-pressure. This causes the occurrence of disaatrous weathers such as drought, water logging, temper-ature anormalies etc. during summer time. ( 4 ) In the year of El-Nino, landing typhoons are less than normal years.
