q The
depth of the mixed layer is determined by (1) the rate of buoyancy
generation and (2) the rate
of kinetic energy supply.
q The atmosphere can affect the mixed layer through three processes:
heating, wind forcing, and
freshening (P-E).
q The global-average depth of the mixed layer is about 70 m.
q The heat capacity of the mixed layer is about 30 times the heat capacity
of the atmosphere.
