摘要
在对2001—2021年西北太平洋热带气旋最大风速半径特征分析的基础上,基于最优风速半径Lin&Fang公式,提出了与方位角相关的四象限非对称最大风速半径计算公式。选取影响浙江沿海的4场历史台风(台风“菲特”、“马勒卡”、“摩羯”、“利奇马”)进行研究,通过与原始公式计算结果进行对比发现,四象限非对称最大风速半径计算公式可以更加准确地模拟台风风速的变化过程,基于该公式得到的风暴潮模拟结果更准确地反映了台风期间浙江沿海地区的最大风暴增水过程。
Based on the analysis of maximum wind speed radius of tropical cyclones in the Northwest Pacific from 2001 to 2021,a four-quadrant asymmetric maximum wind speed radius calculation formula relying on azimuth angle is proposed based on the optimal wind speed radius formula of Lin&Fang.Four historical typhoons("Fitow","Malakas","Yagi","Lekima")affecting the Zhejiang coast are selected to validate the proposed formula in comparison with the original Lin&Fang formula.The results show that the proposed formula simulates the typhoon wind speed change more accurately.The storm surge calculation using the proposed formula products more accurate maximum storm surge along the Zhejiang coast.
