利用1951～2008年2月全球月平均海平面气压资料,计算了冬季北大西洋涛动指数(NAOI).研究表明,NAOI存在间隔不定的周期现象,并且与厄尔尼诺存在着密切的关联.通过NAOI与我国各月气温和降水的相关分析,发现冬季NAOI与我国冬季的降水和气温相关性很强,夏季次之,春季和秋季较差;除春季外,在其余季节NAOI与我国气温的相关性要远大于与降水的相关性.

According to global monthly average data of sea level pressure from 1951 to February, 2008, North Atlantic Oscillation Index in winter (NAOI) was calculated. Research showed that there was a periodic phenomenon with NAOI, and NAOI was closely related to El Nino. Through the correlation analysis of NAOI and monthly temperature as well as precipitation, it can be found that there was a strong correlation between NAOI and precipitation as well temperature in winter, the correlation in summer was relatively weaker, and that in spring and autumn was the weakest. Besides spring, the correlation between NAOI and temperature in China was much greater than that between NAOI and precipitation.
