摘要
通过与观测场作比较，评估低分辨率的大气环流模式（ＡＧＣＭ）模拟的风场。模式风场是使用观测海温场作为外强迫，从１９７９年到１９８８年共积分十年得到的，模式输出为月平均值。结果表明，模式能够相当真实地模拟出风距平场的演变。用风应力距平强迫简单海洋模式（ＺＣＯＭ）（Ｚｅｂｉａｋ－Ｃａｎｅｏｃｅａｎｍｏｄｅｌ），积分十年（１９７９－１９８８），得到的海温距平场（月平均值）和观测海温距平场作比较。模式结果较真实地模拟了１９８２／１９８３年及１９８６／１９８７年暖事件的赤道地区海温距平场的变化特征；对于冷事件的赤道地区的海温场模拟，存在一定缺陷。模拟的ＮＩＮＯ３指数的时间变化基本反映了真实情况。
The purpose of this paper is to evaluate the tropical pacific wind stress anomalies produced on monthly to inter annual time scales by the complex general circulation model (GCM) of the center for Ocean Land Atmosphere Interactions (COLA) at low (R15) resolutions. The model is integrated using observed sea surface temperature (SST)for ten years 1979 through 1988. The model simulates generally realistic wind stress anomaly (WSA).The model generated data set of WSA was used to force the Zebiak Cane ocean model (ZCOM) for ten years.The modeled SST anomalies were compared to the observed SST anomalies. The ZCOM simulation shows realistic 1982/1983 and 1986/1987 warm episodes along the equator,but could produce less realistic 1984/1985 and 1988/1989 cold episodes along the equator,due to lack of wind stress forcing in the ocean model.Time series of the NINO3 index (measuring the SST anomaly in the mid eastern pacific) is realistic for the ZCOM simulation.
