中文摘要：

台风风场是基于数值模拟的台风危险性分析的重要组成部分。基于现有文献资料,以台风风场内空气微团的运动平衡方程为出发点,对现有的基于平衡运动方程的参数化风场模型进行了评述,并建议选用CE风场;回顾了对风场预测结果有重要影响的两个输入参数的信息获得途径,重点就国内台风区城市应该如何处理这两个参数提出了建议;然后从台风边界层的物理意义出发,评述了现有的边界层模型,建议采用Thompson和Cardone所提的具有物理意义的边界层模型;最后对今后工程风场的发展方向提出了一些看法。尽管从气象学角度来看,三维风场是精度很高的模型,但是其工程实用性还有待考证;在满足工程精度的前提下,简单易行的模型是目前进行台风危险性分析的风场数值模拟的较好选择。

英文摘要：

The typhoon wind-field model is an important part of the typhoon hazard analysis.Based on available literatures,the parameterized wind-field models that describe the equation of motion of the air particle were reviewed and the CE wind-field model was recommended.The two ways for obtaining the two key parameters of the wind-field models were discussed,and suggestion about how to treat with these two parameters for the region in south/east China Sea was provided.From the point of view of physical characteristics,the boundary layer models were reviewed and the Thompson and Cardone boundary layer model was recommended.At last,some viewpoints about development trend of typhoon wind field in engineering were presented.Although the 3-dimensional wind field model has higher accuracy in meteorology,its engineering applicability is suspicious at present time.Those models with simple scheme but sufficient accuracy are preferred for the filed simulation in typhoon wind hazard analysis.
