Solar radiation having been absorbed by the atmosphere and underlying surface and then being transformed into other forms of energy regulates all the dynamic processes occurring in the Earth's climate system. The clouds covering a considerable portion of the globe represent the major modulator of radiation energetics of the climatic system. Cloud cover as being subjected to strong variations in its forms and in the space is the major contributor to the dynamics of the radiation regime and brightness fields of the system. In this connection, one of the most important problems in the theory of radiative transfer lies in the study of the effects associated with the extreme spatial variability of clouds as well as in the construction of adequate parameterization schemes of radiation balance of the system `atmosphere-underlying surface' in the numerical models of weather forecast and climate. On the basis of the theory of radiative transfer in the statistically homogeneous cloud fields with stochastic geometry and deterministic optical parameters inside the individual clouds (broken clouds) we intended to evaluate the sensitivity of the mean spectral fluxes of visible solar radiation to the variations in such characteristics as (1) cloud drop size distribution function; and (2) optical parameters of atmospheric aerosol being contained both inside the clouds (as condensation nuclei) and outside them. |
