| 摘 要： | 利用近岸海上气象平台对登陆台风“黑格比”近海层风廓线观测资料,计算分析了近海层大气的湍流动量通量交换参数,以期认识高风速情况下的海气动量交换特征.数据分析结果显示,当海面上方 10 m处风速U10≤24 m/s时,摩擦速度(U*)随风速的增大而增大,当U10＞24 m/s时,U*呈饱和趋势.海面粗糙度长度(Z0)、拖曳系数(Cd)在低风速( U10≤6 m/s)随风速的增大而减小,在U10处于6～24 m/s之间时,Z0、Cd随风速的增大而增大,当U10＞24 m/s时,Z0、Cd达到极值后开始减弱.Z0、Cd极值出现在U10为24～28 m/s之间.并对高风速时拖曳系数衰减现象的对应机制进行了讨论.另外,还探讨了台风期间的阵风因子(G(t,T))等参数的演变特征. |
