Abstract:Using the radar data,surface data and upper air data and NCEP (6-hr interval) reanalysis data on 26 cases of thunderstorm from 2003 to 2009 in eastern Hubei Province,the radar echoes caused thunderstorm gale are divided to three types,namely single-cell thunderstorm,bow thunderstorm and squall-line thunderstorm according to the morphology features of radar echoes.This paper statistically analyses the characteristics of radar base reflectivity,echo tops,vertical integrated liquid,mid-altitude radial convergence,inflow jet,mesocyclone and atmospheric conditions of the three types,and establishes the three radar echo conceptual models based on the evolution of radar echoes caused thunderstorm gale.Results show that the bow thunderstorm and squall line thunderstorm can be warned about 30 min in advance,but it is difficulty to advance the warning of single-cell thunderstorm.
