【摘要】 2007年7月7日南京及周边地区出现了一次大范围的强雷暴天气过程,利用MTSAT卫星的云图资料、多普勒雷达的回波信息以及全国闪电监测系统监测到的闪电资料,结合气象物理参数信息,分析了这次过程中闪电在雷达回波、卫星云图上的表现。结果表明,应用卫星和雷达资料的综合分析,可以判断出闪电发生的时间和位置,从而为雷电的预警提供依据。同时,了解暴雨过程中闪电的频数、分布和极性特征,也有助于分析暴雨的发展过程,预测暴雨的演变趋势。更多还原

【Abstract】 On July 7,2007,Nanjing and the peripheral locality experienced a wide range strong thunderstorm weather process.This article has used the cloud date of the MTSAT satellite,the Doppler radar echo information and the lightning information monitored by the national lightning monitor system,combining with the weather physical parameter information to analyze the characteristics of the lightning in the radar echo and the satellite cloud data.The results indicated that the application of satellite and radar material generalized analysis,may predict the time and the position that the lightning occurs,thus provide the basis for the thunder and lightning early warning.And meanwhile,understanding the lightning frequency,the distribution and the polar characteristic in the rainstorm process,also is helpful to the analysis of rainstorm development process,and the forecasting in rainstorm evolution tendency.更多还原
