Abstract

Abstract: Hubei province strong thunderstorm weather process was analyzed from August 30th to 31st, 2014 considering the circulation background, system mechanism, the radar reflectivity, high echo top, vertically integrated liquid and characteristics of cloud maps etc, by using the observation data of lightning locator, Doppler weather radar and meteorological satellite in Hubei area. The results showed that under the influence of the mesoscale convective cloud system,time and area the lightning occurred correspond to the radar echo. When regional echo intensity mostly above 40 dBZ, maximum reached 45 dBZ, echo top partly above 9 km, maximum was up to 17 km, K index was not below 36 and most of the vertically integrated liquid became more than 6 kg/m², the largest reached 20 kg/m², which became a clear instruction to thunder and lightning to weather forecast.

Key words: lightning forecast, detection data characteristics, correlation analysis, Hubei province
