Аннотация:A new technique for incorporating processes of near-bottom tracer transport over sloping topography in geopotential-coordinate ocean circulation models is presented. It is based on a "hybrid" approach, coupling a simple terrain-following bottom boundary layer model to the standard ocean general circulation model. Tests in simplified configurations show enhanced downslope spreading of passive and active (density) tracers. The method is helpful for both coarse-resolution global climate studies and biogeochemical coastal modeling studies.
