Abstract:
In order to forecast the severe convection events efficiently，two paroxysmal se vere convective events occurred on Jun 7, 2004 and on Jul 31, 2005 are analyzed. The results show that the two weather processes are very difficult to forecast. The synoptic system and the weather phenomenen are different in the two events. The movement speed of the former is more rapidly than the latter. The character s in infrared satellite picture, the Doppler radar echo and lightning site data are also different. The wind on the ground has close relation to the bow echo on the map of Doppler radar base reflectivity and the rapid reduce of Doppler rada r vertical integration liquidwater content. The persistent influence of the high value area of VIL are correspo nding to local heavy rain. The proportion of the cloudflashes in the two weath er processes is different. The nonconventional observation data are very impor tant to the severe convection events forecast.
