Abstract:Using the Variational Doppler Radar Analysis System(VDRAS) combined with local unconventional observation data,a more in-depth contrastive analysis is carried on the initiation mechanism of two storm cases in Beijing,one is 814(August 14,2008) case with strong rainfall that we call it as moiststorm and the other is 824(August 24,2008) case with little rainfall that we call it as dry-storm.The results show:(1) The synoptic-scale systems of 814 storm were stable Northeast cold vortex-low trough at 500 hPa and...
Keywords:moist-storm  dry-storm  cold pool  gust front  vertical wind shear
