Ⅱ:Introduction • The heat capacity ratio or adiabatic index or ratio of specific heats, is the ratio of the heat capacity at constant pressure (C P ) to heat capacity at constant volume (C V ). It is sometimes also known as the isentropic expansion factor and is denoted by (gamma)...
K = R/Cp; Cp is the specific heat at a constant pressure of dry air and R is the gas constant. Ps refers to surface pressure and Pt = 100 hPa. L is latent heat due to condensation, P is the precipitation rate, Qs is surface sensible heat flux and <QR> is the radiative heating...

where T is the temperature of the fluid, K; σcis the Schmidt number of turbulent flow, usually 1.0; σTis the rough Prander number, usually 0.9 ~ 1.0; Cp, Cpa,and Cpvare the constant pressure-specific heat capacity of mixed gas, continuous pressure specific heat capacity of air an...
In this case, the specific heat at constant pressure does not remain constant and varies with the increase of temperature. The stagnation temperature becomes an important parameter in the calculation. The mathematical model is presented by the numerical resolution of a system of first-order nonlinear...
