利用福建沿海海域南日岛、金门岛与广东南澳岛的近海面气象、水文观测资料及台湾海峡西南部与南部的浮标观测资料,通过COARE(Coupled-Ocean Atmosphere Response Experiment) 算法(V3.0),计算了台湾海域近海面空气动力粗糙度、曳力系数及海气表面动量通量,并研究它们关于水平风速的分布规律.结果得出:摩擦速度与10 m风速基本上呈线性分布,线性拟合系数在0.042～0.045之间.曳力系数对10m风速的线性分布与过去研究结果相近,线性拟合系数在0.064～0.067之间.海面空气动力粗糙度对10 m风速的线性拟合系数在0.053～0.058之间.海面动量通量与10 m风速呈明显的二次关系,其线性与非线性拟合系数对于进一步了解台海地区大气湍流结构,建立和完善台海地区数值预报模式可提供重要的参数依据.

The data collected at the Nanri,Jinmen and Nan'ao Islands of Fujian coastal area,and the buoy data used from the southwest and south of Taiwan Strait.By use of the COARE(Coupled-Ocean Atmosphere Response Experiment) algorithm(version 3.0),we calculated the frictional speed,drag coefficient,aerodynamic roughness length and wind stress,and studied their distributions with 10m wind speed above the sea surface.The frictional speed turned out to be linearly related to the 10 m wind speed.The linear fitness coefficient is between 0.042 and 0.045.Similarly,linear relationships between the drag coefficient,roughness length and 10m wind speed were found.The linear fitness coefficients are 0.064-0.067 and 0.053-0.058 respectively.Wind stress performed good quadratic change with wind speed.The linear fitness coefficients and nonlinear fitness coefficients might be valuable to be referenced to providing the basis for parameter value determination for further understanding sea-air interface energy transport,constructing and improving models of climate,wave and sea wind.
