Convection mechanisms of atmospheric heat transfer from surface to global scales
Abstract
The dry convection processes which participate in the transfer of sensible and latent heat in the atmosphere were studied. In the surface layer, the structure of the upward transfer processes is related to height scaled to Obukov's length L. For z/absolute value of L 0.03, wind shear generated forced convection is dominant. For 0.03 z/ absolute value of L 2, the convection is of a composite type involving both wind shear turbulence and buoyancy; thermal plumes appear, but mostly do not reach the upper parts of this height range.
