The results showed that longwave radiative cooling is very important for the formation of the fog in addiation to steady atmospheric stratification and plenty of moisture.

Results show that sub-grid distribution of cloud condensate has obvious effect on downwelling shortwave radiation and out-going longwave radiation, with different sensitive domains from each other.
