| Abstract: | Based on the composite analysis of high-level circulation under the situation of severe convective weather in Pingliang of Gansu Province,the typical field model and environmental field feature at the level of 500 hPa in severe convective weather process were summarized.Meanwhile,the daily unbalanced fields from June to September in 2008 were caculated by using T213 mathematical forecast products,and the relationship between the unbalanced field and strong convective weather was discussed.It showed that dyn... |
