中文摘要:回顾了湿空气热动力学的研究进展,对未饱和湿大气、饱和湿大气及非均匀饱和湿大气的动热力方程、能量方程、连续方程等进行了梳理,指出饱和湿空气动量方程与非均匀饱和湿空气动量方程的最大区别在于对凝结过程的处理不同。饱和湿大气中,由于大气均是饱和的,由饱和造成的水凝物可处处出现,不能区分真正发生水汽凝结的区域。而非均匀饱和湿空气中,凝结发生与相对湿度的幂次方有关(即与凝结概率函数的分布有关),在相对湿度较小的区域不会出现水汽凝结,凝结区与非凝结区可自动区别,其描述的凝结过程与实际大气更接近。同时,总结了湿大气水汽凝结饱和非均匀分布的动热力物理量在高影响天气分析中的应用,最后讨论了未来推进湿空气动力学研究需重点考虑的一个内容。

Advances in the kinetic thermodynamics of moist air and their application
Abstract:In this study,the kinetic equations,thermodynamic equations,energy equations and continuous equations of unsaturated moist atmosphere,saturated moist atmosphere and non-uniformly saturated moist atmosphere are combined by reviewing the current research progress of moisture atmospheric thermal dynamics.It is observed that the most notable difference between the saturated and the non-uniform saturated moist atmosphere momentum equation is the distinctive method that is used while dealing with the condensation process.In saturated moist air it is difficult to distinguish the veritable moisture condensation area,as the hydrometeors caused by saturation probably appear ubiquitously,while it is easy to discriminate between the moist condensation area and non-condensation area in a non-uniformly saturated moist atmosphere.Due to the fact that water vapor will not condensate in the area with smaller relative humidity,as the generation of the moist condensation is concerned with the exponentiation of relative humidity (as well as the distribution of the condensation probability function),this condensation procedure is more similar to that in an actual atmospheric environment.Furthermore,this paper summarizes the application of the non-uniformly distributed dynamical and thermal physical quantities of moisture condensation saturation in moist air as observed in high-impact weather analysis,and finally discusses of the dominant problems that may arise in the future study of moisture atmospheric dynamics.
