中文摘要: 使用常规气象资料、HLAFS资料、红外云图以及中尺度分离技术等对2002年7月24~25日出现在威海市的大暴雨过程进行了分析。结果显示这次大暴雨过程是在西风槽与副高西部边缘西南气流相互作用的大尺度背景下,上升运动区内新生的中尺度气旋引起的强烈的水汽辐合上升造成的,大暴雨区上空高层强烈的辐散对强降水的维持有重要作用。
中文关键词: 中尺度气旋,大暴雨,副高,西风槽
Abstract:A meso-scale heavy rain occurred in Shongdong Weihai city during June 24 to 25, 2002 is analyzed with synoptic map, the satellite image, HLAFS data and Shuman Shapiro meso scale filter. The result shows that under the background of interaction between high-level westerly trough and southwest flow on the western border of Western Pacific subtropical high, the event was mainly caused by meso-scale cyclone in the uscending area.
