中文摘要:
      详细介绍了光滑面标量粗糙度ZT,Zq与风速粗糙度Z0的相似表达式,论述了把Monin-Obukhov相似理论推广到光滑面上湍流气层的合理性,从而得到光滑面风、温、湿层结订正廓线与粗糙面廓线相统一的形式。总结了用该模式处理的三个海上梯度观测资料的计算结果,揭示出了微风时通过光滑海面的海气通量及整体交换系数受层结影响远大于风速影响的特征。并给出光滑界面上不同层结的整体交换系数随风速变化的拟合公式。
英文摘要:
      In this contribution,the formulae of the scalar roughness Zt,Zq,similar to the wind speed roughness Z0 overa smooth sea surface,are introduced in detail,and extending the Monin-Obukhov similarity theory to smooth surface.Stratification modified profiles of wind,temperature and humidity over smooth surface are obtained in uniform with the profiles overa rough one.Reasonability of the theory is also discussed.The model is applicated in the computation of the gradient data observed in three differentsea areas.It's resulted that the effect of stratification on the air-sea flux through a smooth sea surface and on the bulk transfer coefficients under light wind are much stronger than the effect of wind speed.The formulas of the bulk coefficients variation with wind and stability is presented.
