摘要
Abstract
One strong convective process occurred in Chongqing province in the morning on May 6. 2010. The strong convective storm caused thundderstorms ,hailstorms and gale.The conventional weather observations, the data of Doppler radar and the 1°x 1°re-analysis data of NCEP were used to analyze the event. the result indcated that the warm tongue at 850 hPa and cold air at 700 hPa were the circulation background of the strong convective storm. The low energy tongue located above high energy tongue caused atmospheric convective instability,the air convergence and rising motion produced by mesoscale occlusion front and low prssure trough at the 975 hPa triggered convective instable enegy released so as to produce strong convective storm; the positive vortex corresponded to the convergence area. The convergence in the lower layer and divergence in the upper layer were conductive to the generation and development of strong convection; there was strong vertical wind shear in 850 - 200 hPa, especially strong vertical shear in the lower and higner layer and mild change in the middle layer, which was conductive to the development and maintenance of strong convection; radar echao analysis suggested that supercell form caused hailstorm in Chongqing.关键词
