Abstract: Using FY-2E cloud top temperature and vapor cloud to Analysis the Features about lightning at Low Latitude Plateau，found that lightning was produced in the high value area of the mobile side of the top cloud temperature gradient in convective clouds,lightning was produced in near the low cloud top temperature for convective clouds,the Vapor temperature about the area of linghning produced was Less than -20 degrees.Analysis of high lightning frequency of station,the Vapor temperature at -40 degrees and cloud top temperature at 0 degrees before the lightning produced,before three hours about Lightning produced the top cloud temperature and water vapor temperature was decreasing trend.According to the quantitative analysis of the characteristics of the convective cloud top temperature and water vapor temperature,can determine the location and intensity of lightning,to further improve the early warning of lightning,lightning activity,but also can be used to determine whether the occurrence of other severe convective weather.
