中文摘要:

      距平滤波模式(AFM)是具有独特优点的长期天气预报模式,本文推广进而设计了一类全球大气多层原始方程距平谱模式,并利用该模式对热带海温距平产生的大气响应进行了试验性模拟,结果表明多层原始方程距平模式不同于AFM,更有别于GCM,在短期气候异常的动力学过程研究或预报方面显示出广泛的应用价值。

英文摘要:

      Anomaly Filtering Model (AFM).developed originally by Chinese meteorologists, possessed its own unique advantage, as a long-range weather forecasting model. Based on the idea, a multi-level, primitive equation anomaly spectral model of global atmosphere has been designed, and by the model, atmospheric response to the tropical SST anomaly has also been experimentally simulated. It is shown that the model is different from both the AFM and the GCM, and also displays an extensive applied value in study or in prediction of short-term climatic anomaly.
