摘　　要：对近年来台风风场研究及其数值模拟方法作了论述.阐述了浮标和地面台站观测、飞机侦察、雷达卫星高空观测等台风观测手段;阐明了简易参数分析模型、定常动力学模型、非定常动力学模型、运动学模型等台风风场模型;分析了既有风场模型对我国东南、华南沿海海域台风风场模拟的适用性,又论述了基于台风内各站点、基于台风影响区域、台风全路径等极值风速预测研究手段.最后,展望了台风风场数值模拟的发展趋势和需解决的问题.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, air- craft 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.
