本文利用综合海洋大气资料(COADS),对印度洋、太平洋近赤道地区的风场,气压场和海温场进行了综合分析。指出由于南印度洋和东南太平洋赤道地区海平面气压的seesaw现象,导致印度洋和太平洋赤道地区风场同样出现了seesaw现象。风场的seesaw又导致印度尼西亚和东太平洋赤道地区的海温出现seesaw。埃尔尼诺是海洋对印度洋的季风系统和太平洋的信风系统联合的强迫响应。
In this paper, a comprehensive analysis of the wind field, atmospheric pressure field and SST field in the Indian Ocean and the Pacific equatorial regions is carried out by using integrated ocean atmospheric data (COADS). Pointed out that the seesaw phenomenon also occurred in the wind fields in the Indian Ocean and the equatorial Pacific due to the seesaw phenomenon of the sea level pressure in the southern Indian Ocean and the equatorial Pacific Ocean. The windsaw seesaw in turn led to seesaw in SST in Indonesia and the equatorial regions of the Eastern Pacific. El Nino is a coercive response by the ocean to a combination of the Indian Ocean monsoon system and the Pacific letterhead system.
