强对流天气过程成因及系统结构特征分析

Analysis on the Cause of a Strong Convection Weather Process and Its System Structural Characteristics

利用多普勒天气雷达资料、MM5模式资料对2005年4月20日发生在江苏境内的一次强对流天气过程进行了分析,讨论了这次强对流天气的成因,并结合多普勒天气雷达资料及模式资料,对强风暴系统的特征及其演变进行了较详细的描述,揭示出强风暴云体内部动力场的结构特征,为分析和预报强对流天气的发生发展提供了一些可参考的信息。

Using Doppler weather radar data and MM5 meso-scale mode data, a strong convection weather process occurred in Jiangsu Province on Apr. 20^th of 2005 was analyzed. And the causes of the strong convection weather were discussed. Combining with Doppler weather radar data and node data, the characteristics of strong mode data system and its evolvement were described in detail. The structural characteristics of the dynamic field in the strong storm cloud were revealed, which provided some reference information for analyzing and forecasting the occurrence and development of strong convection weather.
