A Brief Report of Graphic Explanations for Generalized Potential Temperature in the Non-Uniformly Saturated Atmosphere

Compared to potential temperature(θ) in the dry atmosphere and equivalent potential temperature(θe) in the saturated atmosphere,generalized potential temperature(θ*) has already proven a better thermodynamic parameter in describing the non-uniformly saturated real atmosphere.To add otherwise absent graphic explanations,this paper first presents the physical definition of θ* through a tephigram.Then,the utility of the measurement in identifying and forecasting the locations of precipitation maxima and heat wave areas with diagnostic comparison studies and traditionally used thermodynamic parameters is shown.

Compared to potential temperature （θ） in the dry atmosphere and equivalent potential temperature （θc） in the saturated atmosphere, generalized potential tem- perature （θ＂） has already proven a better thermodynamic parameter in describing the non-uniformly saturated real atmosphere. To add otherwise absent graphic explanations, this paper first presents the physical definition of θ through a tephigram. Then, the utility of the measurement in identifying and forecasting the locations of precipita- tion maxima and heat wave areas with diagnostic com- parison studies and traditionally used thermodynamic parameters is shown.
