Abstract

The upward and downward fluxes of longwave radiation are simulated for the atmospheric conditions observed in summer and winter in Lower Volga region. The discrepancies in the longwave fluxes in the radiative block of the RegCM climatic model due to use of different water vapor continuum models are estimated. The continuum models used in NCAR CCM3 and RRTM radiation schemes in the regional climate model RegCM 4.5 are considered.
