Sbl strength

From Glossary of Meteorology



SBL strength[edit | edit source]

The air temperature decrease near the surface when the surface is colder than the air.

For a nocturnal SBL over land, it can be measured as the potential temperature difference between the residual layer and the air temperature near the ground. Inversion strength increases as greater cooling continues over longer times and decreases with increasing wind speed and turbulent mixing.


The temperature indicated by a thermometer exposed to the air in a place sheltered from direct solar radiation.
