摘要
本文从大气热力学的基本特征出发,引入了代表饱和湿空气焓的特征量的广义温度,并推导了一组饱和湿空气动力学方程组。还提出了温平衡风(或称湿地转风)、假相当位温风(或称湿热成风)的概念;对低空急流等若干基本特征也作了探讨。
By use of the so-called generalized temperature of the saturated moist air,a characterictic quantity representing the enthalpy of the air and a set of dynamic equations are derived.On the basis of them,the concept of the moistbalanced wind(or moist geostrophic wind)and that of pseudoequivalent temperature wind(or moist thermal wind)are suggested,Finally,some fundamental behaviours of low-level jet streams are studied.
