| 摘 要： | 应用常规观测资料和雷达、自动站资料,分析了2009年8月27日一次突发性强对流天气过程的成因。结果表明,这次过程中对流层中低层具有暖湿层结,高层冷空气的扩散使不稳定层结产生,通过卫星水汽图像分析可以追踪高空冷空气动向,地面辐合线为强对流的发生起到触发作用。

| Abstract: | The causes for a severe convection event occurred on Aug.27,2009 were analyzed by using conventional observation data and radar,and automatic weather station data.The results showed that there is a warm moist stratification in the lower troposphere during the process,the spread of the upper cold air produced the instability stratification.Through analysis of satellite water vapor image,the tendency of upper cold air was tracked,and then the occurrence of severe convection was initiated by the ground convergence line. |
