用湿静力能和总合水量方程代替位温方程,采用Lilly的修正形式卷夹方程,并考虑水平流场作用,建立了包括水汽、液态水和辐射的湿混合层模式,研究定常条件下混合层厚度、云底高度、混合层内各物理量以及它们的湍流通量对各种参数和外参数的响应,并利用此模式,采用AMTEX’75资料研究东海上大气混合层的热力结构和各物理量随海面温度、大尺度散度等的变化规律,并与加利福尼亚沿海大气混合层的一些特性进行比较。
The static temperature equation is replaced by the equations of wet static energy and total water, and the wet mixed layer model including water vapor, liquid water and radiation is established by using the modified form of Lilly’s curling equation and considering the horizontal flow field. Under normal conditions The thickness of the mixed layer, the height of the cloud bottom, the physical quantities in the mixed layer and their turbulent fluxes on the various parameters and the external parameters, and using this model, using the AMTEX’75 data to study the thermal structure of the atmospheric mixing layer in the East China Sea The variation of physical quantities with the sea surface temperature, large-scale divergence and so on are compared with some characteristics of the coastal California atmospheric mixing layer.
