Surface renewal model

From Glossary of Meteorology

surface renewal model

A turbulent exchange model that assumes that fluid near a surface is intermittently replaced by well-mixed fluid from adjacent layers, thereby disrupting the viscous sublayer at the surface itself.

Near-surface gradients are assumed to be restored by conduction according to
where T is temperature and κ is thermal diffusivity.
