Fog And Stratus - Typical Appearance In Vertical Cross Sections
by FMI
- Relative humidity:
A moist lower troposphere and relatively dry layers above typical for both radiation and advection St/Fog. - Total Cloud cover:
High (over 80%) cloud cover either very near or at the surface (both fog types ) or slightly lifted off the surface (advection St/Fog). - Isentropes:
Potentially stable situation at the lowest part of the troposphere. - Temperature:
Surface (for both fog types) or elevated (for advection Stratus) temperature inversion.
