| Abstract: | The Barnus bandpass filtering method was applied to analyze two high wind and hail events,which occur in spring over the southern Yunnan.The results show that there are mesoscale waves within the lower atmosphere near Kunming Quasi stationary Front before the convective weather happens.The area of high wind and hail includes a sinking motion center and a ascending motion center. |
