Diagnostic Analysis of Dynamicals of Damage Wind Caused by Landing Typhoon in Jiangsu Province

Kinetic and develoed mechanism of the damage wind caused by the No.0515 typhoon Khanun in Jiangsu province was studied by the diagnosis of physical quantity.The results showed that wind vector was consisted of vorticity wind,divergence wind,strength transfiguration wind and shear transfiguration wind.Vorticity wind was the fundamental wind of typhoon.It maintained and developed typhoon wind field,also it was main wind vector that caused the damage wind in Jiangsu.Divergence wind contributes on the level wind field of typhoon minimumly.It was the main driving force of convergence and ascending motion at low level.Transfiguration takeed more obvious action on the divergence and chance of the intensity of damage wind outer of typhoon.It also takeed the main action of the typhoon turns direction.
