THE UPPER OCEAN LAYERS,
Abstract
The small and mezo-scale dynamical processes that occur in the ocean above the thermocline are discussed. This region is divided naturally into three separate layers, each being dominated by different dynamical effects. Very near the sur face there is a conductive sublayer, dd esti mates are given for the thickness and temperature difference across this region. The influences of surface ilms are discussed. Below this is a forced convection layer (the mixed layer) where the wind stress provides the dominant energy source for the turbulence. Expressions are given for the thickness of this layer (the Monin Obuchow length, L) and compared to the available oceanographic data from Project Compare. The temperature, salinity, and velocity profiles in this region are discussed also. Below the forced convection layer is a region where buoyancy forces dominate. When the stability is positive, any natural motions are in the form of internal waves. Under unstable conditions, convection plumes form between the depth ''L'' and the thermocline. Characteristics of the motion, as inferred from experimental data, are described. (Author)
