中文摘要: 对晋中1974～2000年6～8月暴雨个例进行了分析,指出700hPa上形成于34～37°N、95～103°E附近的西北涡或28～34°N、93～97°E附近的西南涡是晋中夏季暴雨的最原始触发机制,与之相配合的高低空形势不同,所产生的暴雨的范围不同,水汽输送通道和切变线位置是判断暴雨落区的重要因素。
中文关键词: 西南涡，西北涡，暴雨
Abstract:After detailed analysis of summer heavy rainfall in Jinzhong, Shanxi Province from 1974 to 2000, it is pointed out that the northwest vortex (34-37°N, 95-103°E), and the southwest vortex (28-34°N, 93-97 °E) over 700hPa are the most original trigger mechanism of summer heavy rainfall in Jinzhong city. The vortexes, the high-and low-layer synoptic patterns, the vapor passage and the position of wind shear line could be taken for the factors to forecast heavy rainfall in this area.
