Paper Abstract

Influence of effects, caused by stochastic cloud geometry, on integrated radiative characteristics of one-layer broken clouds has been studied. It is shown that the difference between the mean fluxes of shortwave radiation in cumulus and equivalent stratus clouds may amount to tens of percent. An increase of the height of cloud top boundary causes a 10- 15% increase in albedo at the top of the atmosphere, while leaving transmittance at the surface level unaffected. The influence of cloud top height on absorption in clouds and in the entire atmosphere is discussed. It is shown that the parameterization of the mean shortwave radiative fluxes, developed previously for low-level clouds, can also be used for water-droplet clouds with top height of up to 7 km.
