Abstract:

The effect of the power–law and exponential functions of horizontal cloud size distribution on the formation of the mean radiative regime under conditions of broken clouds has been evaluated. The mean radiation fluxes have been estimated for the models with the random horizontal size of clouds and with clouds of constant (effective) diameter whose value for the statistically uniform models is determined from the condition that the probabilities for the viewing direction to be occluded are equal. It has been shown that proceeding to the statistically nonuniform models in the presence of a small number of large (up to several kilometres) clouds results in the significant transformation of the mean radiative regime.
