摘　　要：降雨高度是地－空路径雨衰减预测中最重要的参数之一。本文简要叙述了降雨情况下0℃等温层高度和温度剖面的分布特性，详细介绍了雨高模型，该模型是根据中国西部山区降雨期间高空测量数据得到的。最后将该模型和CCIR雨高模型作了比较。The rain height is used as one of the most important parameters, to predict rain attenuation along an Earth-space. In this paper, the distribution characteristics of the 0℃ isotherm height and temperature profile during rainy conditions are simply presented. The model of the rainfall height is introduced in detail. This model is derived on the basis of aerological data measured during rain at mountainous area in Western China. Finally, it is compared with the model of rainfall height given in CCIR.
