# Local free-convection similarity

From AMS Glossary

## 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*z*_{i}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.
