摘    要:基于数值模拟方法进行台风危险性分析去估算重现期极值风速,在国内外已得到普遍采用.进行台风数值模拟依赖于台风风场模型,不同的台风风场模型对同一地区的适应性并不一致.通过阐述几种典型的台风风场模型,并利用台风Betty(87)和York(99)两个台风实测风速和风向记录对这些台风风场模型进行对比验证,为极值风速推断选择适合于我国东南沿海的风场模型.

关 键 词:台风  风场模型  数值模拟

Abstract:Based on numerical simulation methods,using Typhoon risk analysis to estimate a return period of maximum wind speed,has been widely adopted both at home and abroad. Typhoon numerical simulation relies on Typhoon wind- field model. The adaptation of different Typhoon wind- field models is not consistent in the same region. This paper describes some typical Typhoon wind- field models and uses the measured wind speed and direction records of Typhoon Betty( 87) and York( 99) to verify Typhoon winds models. This work is to choose the best wind- field model for the extreme wind speed inferred in China's southeastern coast.
Keywords:Typhoon  wind-field model  numerical simulation
