摘要
运用GMS红外云顶亮温（TBB），分析了1998年6月我国南方地区大范围持续性暴雨的成因。结果指出：它是由北方较强冷空气经华北一带源源不断南下，与较弱的西南季风在江南至华南一带汇合而形成，其中冷空气频繁南下是最主要原因；TBB旬平均和距平场，定量而又直接地展示了产生强降水云系的强度、分布特征及其成因。
The reasons of continuous heavy rainfall over a large area in South China in June 1998 were analysed using black-body temperature (TBB ) data from GMS. The results show that such heavy rainfall is caused by the stronger cold air coming from northern China and frequently dominateds its merger with weaker southwest monsoon: The TBB dekad mean and anomaly fields could directly and quantitatively present the features and causes of the intensity and distribution of the cloud system with heavy rainfall.
