摘要
利用一个具有门限的非线性随机动力气候模式对中国东部江淮流域的降水进行了分析。结果表明：在不同的门限域中，降水对外部强迫的响应有明显差异，呈现出一定的非线性特征；模式能较好地拟合降水的变化趋势。
This paper applies a non linear stochastic dynamic model with threshold to analyze the rainfall in the Yangtze and Huaihe river basins of east China.The results show that there are obvious differences of the responses of rainfall to external forcing in different threshold regions,indicating some non linear characters.The model can simulate the variations tendency of the rainfall satisfactorily.
