Mixed Layer Processes
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.
