中文摘要: 利用MM5数值模式模拟了2000年10月发生在海南岛的特大暴雨天气过程。结果指出,这次特大暴雨发生在南海低压和大陆冷空气的交汇区上,交汇区的东西长度约为800km。冷暖空气的交汇产生了持续的上升运动,交汇区内产生了大范围的特大暴雨,海南岛的陆地降水仅仅是其中的一部分。交汇区具有弱冷锋的热力结构。
Abstract:A heavy rain event in Oct.2000 of Hainan Island is simulated with numerical model MM5. The result indicates that the event occured at the stream convergence area of South China Sea depression and north cold air. The length of convergence area is about 800km from west to east. The convergence of warm and cold air produced the strong ascending motion, then derived the heavy rain in the large area. The precipitation in Hainan Island is a part of the event. Furthermore, the convergence area possesses the characteristics of the weak cold front.
