中文摘要：

通过求解赤道β平面上的线性运动方程,研究了热带大气对主要由海洋热状况异常导致的大气非绝热加热的响应,并探讨了该过程与ENSO循环的关系。结果表明,非绝热加热的直接作用及其产生的Kelvin波、Rossby短波是大气零阶的扰动位势和纬向风速变化的原因。在El Nino期间,大洋西部首先发展出正的大气位势异常。但随着海洋热状况的正异常的持续,随之在大洋西部即开始孕育和发展,导致热带太平洋海气耦合系统回归正常状态,甚至是转向La Nina的大气异常状态或系统,其标识是非绝热的异常加热所激发的大气Kelvin波的产生和东传,并伴随正位势异常的大值向东移动和大洋西部正的位势异常减弱,信风由此而增强。在La Nina的盛期,海洋热状况存在负异常（即弱于平均状态）,则将有相反的过程。

英文摘要：

By resolving the linear adiabatic equations on equatorβplane, the response of tropical at-mosphere to diabatic heating caused by oceanic heating anomaly was studied, moreover, its relations withENSO were also analyzed. Results show that the direct effect of diabatic heating and its resulting Kelvinwave, Rossby short wave are the reasons for the variation of zonal wind speed and disturbed geopotency ofatmospheric zero class. During El Nino period, the positive atmospheric geopotential anomaly firstly de-veloped in the West Pacific, but with the persistency of the positive anomaly of the oceanic heating, anatmospheric anomaly occurred and developed in the West Pacific, which caused air-sea coupled system toreturn to normal condition or to La Nina. The identification of the above situation were the occurring andextending eastward of Kelvin wave triggered by diabatic heating anomaly, companied by the eastwardmovement of the large value of positive geopotential anomaly and the weakening of the positive geopoten-tial anomaly in the West Pacific, so that the trade wind could strengthen. During the period of the stron-gest La Nina, the oceanic heating turned to be negative anomaly（weaker than the average）, it means thereverse situation could take place.
