Inertial sublayer

From Glossary of Meteorology



inertial sublayer

A sublayer in wall-bounded shear flows characterized by a sufficiently large Reynolds number and a logarithmic velocity profile (e.g., the atmospheric surface layer); so called as an analogy with the inertial subrange of the turbulence kinetic energy (TKE) spectrum, where viscosity provides a sink for momentum as dissipation provides a sink for TKE in the inertial subrange.
