Abstract:

We amend the free convective mixed layer velocity scale, w to ws to include mechanical turbulence from forced convection. Ws has discrete surface layer, entrainment zone, and baroclinic components and requires the length scales zo, L, Delta h, zi, and zb, a newly defined baroclinic length. To close the system we offer simple models for delta h, the entrainment zone depth. The delta h models show realistic diurnal hysteresis, using a critical bulk Richardson number which exceeds unity.
