摘　　要：设计了一种用滤波法校正船载超声测风测温仪数据、计算海一气通量交换 的方法。对１９８８，１９８９两年西太平洋海域考察期间超声测风测温仪的实测资料作了 订正，订正了船体运动、特别是摇摆运动对风速的影响，用涡旋相关法计算了海面 边界层的感热通量、动量通量、阻力系数和稳定度值。分析了海面上通量、阻力系数 随大气状况的变化规律。计算结果表明，海面上的通量、阻力系数与水平风速和稳 定度之间存在着合理的有规律的关系，证明这种方法对处理船载超声资料是可用 的。A correct estimation method of heat the momentum fluxes at the interface between air and sea by fil- tering is introduced in this paper. We corrected the measured on ship with ultrasonic anemometer/ther- mometer at West Pacific Ocean during the seventh five-year program, abated the impact of ship-body mo- tion, especially the rolling movement on wind data, and calculted the sensible heat flux, momentum flux, drag coefficient, and stability parameter in the over as boundary layer with eddy correlation method,anal- ysed the variation regularity of fluxed and drag coefficient with the atmospheric condition. The conclusion is that there are reasonable and regular relations between fluxed, ding coefficient and horizontal wind com- ponent, stability condition in the over sea boundary layer, which indicates that this correct estimation method is useful for correction of turbulent wind contaminated by irregular motion of ship.
