利用南京多普勒天气雷达资料,对南京地区2003年7月8日出现的一次雷雨大风和短时强降水过程进行了分析,结果表明:这次强天气过程与多普勒天气雷达观测到的中气旋相联系,文中结合环境风场分析了中气旋的特征,计算了中气旋的主要参数。
Based on the Doppler weather radar observations, a weather event of severe thundery precipitation and gale over Nanjing region of Jiangsu province on 8 July,2003 have been analyzed. The results show that the event had something to do with a few mesocyclones detected by Doppler radar. Combined with the environmental wind fields, some characteristics of the mesocyclones were analyzed,and some primary parameters of them were calculated.
