Local free-convection similarity

From Glossary of Meteorology

local free-convection similarity

Similar to mixed-layer similarity as a way to find empirically universal relationships between boundary layer variables, except using a general height z in place of the depth of the mixed layer zi and using local values of fluxes at height z (including in the definition for Deardorff velocity).

This approach is designed for use in the statically unstable surface layer.
