Abstract:
Mean fluxes of solar radiation at different atmospheric levels are calculated by two different methods: (1) approximate method (under assumption of random cloud overlap) and (2) method of closed equations based on the Monte-Carlo solution of equations for mean intensity in two-layer broken clouds. Calculations are made for characteristic parameters of typical cloud systems
(St) – (As), (St) – (Ci), (Cu) – (As), (Cu) – (Ci) at midlatitudes of the Northern Hemisphere. It is shown that, depending on the geometrical cloud parameters, the relative difference in upward and downward radiative fluxes between calculation techniques may reach tens of a percent.
