| Abstract: | By analyzing the relative data and comparing with similar historic cases, the characteristics and causes of typhoon Sally are analysed here. The conclusions are: Sally is characterized by stable track, quick movement, quick offshore development and strong landing intensity, etc. The strong and stable west Pacific high pressure and the warm zones in the middle troposphere are the major causes of the stable track and quick movement of the typhoon. The strong and stable subtropical high pressure, the high relative humidity in the middle troposphere, the water vapor convergence in the lower level, and the divergence field in the upper level provide advantages to the offshore development of the cyclone. |
