2016年初夏一次局地强对流天气过程分析

摘要

利用常规观测资料、区域自动站加密观测资料和郑州多普勒雷达产品,对2016年6月4日新乡地区一次局地性强并伴有雷暴大风、冰雹和短时强降水等灾害性天气的强对流天气过程的环境背景和多普勒雷达产品特征进行了分析.结果表明:高低层温度平流差动加强了层结不稳定,为对流天气提供了良好的环境背景条件;入流气流温湿状况及雷暴高压的出流可影响新生对流的发生发展;多普勒雷达产品对强对流天气的预报预警有较强的指示作用.%By using the conventional observation data,regional observation data and radar data of Zhengzhou,a local severe convection weather accompanied with thunderstorms,hail and short-time heavy rainfall in June 4,2016 of Xinxiang was analyzed through the environmental conditions and the characteristics of doppler radar products.The results showed that the different temperature advection of upper and low which strengthened the instable convection stratification provided an advantageous environmental condition for convection generation. The temperature and humidity conditions of the inflow and the outflow of the thunderstorm affected the occurrence and the development on the new convection. The doppler radar products were highly indicative to forecasting and warning of severe convection weather.
