Typhoon Wind-Field Research and Its Simulation

Abstract： Investigations on typhoon wind-field and the numerical simulation in recent years were summarized．Typical and actual typhoon measurement methods such as Buoy and ground stations observation， aircraft reconnaissance，radar and satellite reconnaissance were included．Several kinds of typhoon wind field simulation models and their applicability in southern China seas were fully elaborated，including simple analytical parametric wind models，steady state dynamical models，non-steady dynamical models and kinematical models．Furthermore，prediction of extreme wind velocities based on the site in typhoon，the typhoon influence area and entire track of typhoon were mentioned in detail．Finally the development trends and some problems to be solved in this area were given.
