| 内容記述 | It is shown that the effects of radiative heating or cooling can have a substantial influence on the mass budget of a cloud droplet and thus on the microphysical properties of a cloud as a whole. The radiative transfer equation, including all orders of multiple scattering, is solved for spectral windows of earth's atmosphere by adopting the Eddington approximation and assuming that the cloud is isothermal and illuminated by fluxes from both the ground and the sky. The results obtained for the 8-12-micron window indicate that radiative cooling can increase a droplet's growth rate and may also make the droplet cooler than the surrounding gas while water vapor is diffusing in, which would cause diffusiophoreisis and thermophoreisis to combine and increase the efficiency with which droplets would scavenge aerosols. |
