摘要
文献所给计算蒸发力E_(0)的М·И·Будыко公式为:E_(0)=ρD(q_(s)-q’_(a)),(1)其中,ρ为空气密度,D为外扩散系数,q_(s)为与蒸发面温度T_(s)相应的饱和比湿,q’_(a);为空气的实际比湿。
In this paper,M.I.Budyko’s()method on calculation of poten-tial evaporation(E0)is simplified,and obtained a formula which is similar to H.L.Penman’s method:■where■In the above equation,R0 is the radiation balance of the evaporation surface(mm/day);Q is the heat flux into the ground(mm/day);of the evaporation surface.
