中文摘要: 利用NCEP再分析场、红外卫星云图的TBB值和常规观测资料对2003年7月9—10日长江流域梅雨锋上的一次大暴雨天气过程的成因进行了分析。结果表明这次梅雨锋暴雨是在有利的高、中、低层系统配置下,不同纬度带环流相互作用的结果,中β尺度深对流系统是暴雨的直接影响系统。但梅雨锋西段和东段暴雨的影响系统不完全相同。这次梅雨锋的锋面结构既有典型梅雨锋的一般特点,又有其独特的特征,在该次梅雨过程中不同地区梅雨锋的结构不同,梅雨锋的结构是多样的。

Abstract:Based on the NCEP, TBB and observation data, the study of a torrential rain along Meiyu front in Yangtze River during July 9—10, 2003 is made. The diagnostic results show that the torrential rain on Meiyu front developed under the favorable environmental fields to cooperate with synoptic systems between the upper, middle and low levels through the interactions of circulations among different latitudes. The direct influencing system of torrential rain is β convective system. But the influencing systems in two regions are slightly different. The structure of Meiyu front has unique characteristics apart from typical feature. The structures of Meiyu front are different in two areas and the diversities of complicating structures of Meiyu front are revealed.
