Abstract:
In general, the subtropical high severe convection can be easily misforecasted. For this reason, the 19 samples of subtropical high severe convection from 1 July to 30 September during 2001-2005 in Shanghai area were analyzed and compared to the samples without severe convection when Shanghai area was dominated by subtropical high aloft. The results have shown that subtropical high severe convection occurred more frequently in the north part of subtropical high and time period mainly from noon to evening. Subtropical high severe convection happened in the condition of strong instability and strong lifting such as boundarylayer mesoscale convergence line nearby Shanghai.
