中文摘要:
      对现有的大气模式中计算海面和大气间水、热通量的通量-廓线关系式进行了评论,提出一个理论上较完整的通量-廓线关系式。其中考虑了水汽对M-O参数的影响,并引进相应于虚位温的标量粗糙度。Moana Wave的实测资料表明,由于该资料相应于温度的粗糙度zoh和湿度粗糙度zoq相差不大,使现有的公式计算结果与文中提出的公式差别不大。当zoh,zoq差别大时,两种公式结果有一定的差别。而文中公式理论上更为合理。还将不稳定状态下计算通量的简化方法推广到海面。
英文摘要:
      The formula of flux-profile relationship to compute the moisture and heat fluxes over sea surface in the current atmospheric models is reviewed,and a new flux-profile relationship formula is suggested which is more reasonable theoretically,in which the effect of moisture on Monin-Obukhov parameter is considered,a scalar roughness for virtual potential temperature is introduced.The computation of Moana Wave data shows that the difference of the computed results between the current formula and the formula suggested in this paper is small over sea surface because the difference between the roughnesses for temperature and humidity is not great for the used data.When the difference between these two roughnesses is great,some differences appear,the formula in this paper is more reasonable.We also extend the simplified method for the computation of the fluxes in which the effect of moisture was not considered to sea surface in unstable condition.
