Abstract
We amend the free convective mixed layer velocity scale, w* to w* s to include mechanical
turbulence from forced convection. w* s has discrete surface layer, entrainment zone,
and baroclinic components and requires the length scales: zq, L, Ah, z-^, and z^, a
newly defined baroclinic length. To close the system we offer simple models for Ah, the
entrainment zone depth. The Ah models show realistic diurnal hysteresis, using a
critical bulk Richardson number which exceeds unity.
