Abstract A shallow convection scheme is derived from several data sets
(BOMEX, GATE, AMTEX, BLX83) and developed for the OSU 1-D boundary
layer model. Results of the model structure and characteristics of
the saturation point (SP) profile are compared against the constant
cloud diffusivity scheme of Tiedtke (1983) and the ECMWF boundary
layer parameterization scheme.
The results indicate that the primary mechanism that transports
moisture away from the lower boundary layer is the boundary layer
turbulent flux and that the boundary turbulent mixing alone is
capable of maintaining an apparent moisture source near the
inversion. While the sensible heat flux over ocean becomes quite
small after a few hours of model simulation, the virtual heat flux
remains positive and the boundary layer remains in the unstable
regime.
