摘要
发展了一个线性热带西太平洋两层模式 ,分别为混合层和温跃层 ,其密度、温度各不相同 .利用这一模式分析了热带西太平洋对纬圈风应力的响应 ,求出西边界的解 ,以及解析地求得热带西太平洋温跃层厚度、洋流及海温分布 .结果表明 ,热带西太平洋物理量的变异在ElNino LaNina事件中起着重要作用 ,在温跃层中海温变化的振幅明显大于混合层 ,这从理论上支持了近年来的观测事实 .
A linear west tropical Pacific model is developed in this paper, which consists of a mixed layer and the thermocline with different temperature and density. By analyzing the barometric response of west tropical Pacific to wind stress, the distribution of termocline dense, current and sea temperature can be obtained analytically. The result shows that anormal variation in west tropical Pacific acts greatly in El Nino/La Nina, and also the amplitude of thermocline temperature is much greater than that of mixed layer. It is in associated with the observed facts found in recent years. [
