Downwelling is the process of accumulation and sinking of higher density material beneath lower density material, such as cold or saline water beneath warmer or fresher water or cold air beneath warm air. It is the sinking limb of a convection cell.
downwelling"A downward motion of surface or subsurface water that removes excess mass brought into an area by convergent horizontal flow near the surface. See also upwelling.
downwind gustiness"See gustiness components.

Downwelling(1)
The process of accumulation and sinking of warm surface waters along a coastline. A change of air flow of the atmosphere can result in the sinking or downwelling of warm surface water.

Radiational cooling occurs, as is typical on calm, clear nights, whenever the longwave emission from the surface is not balanced by significant amounts of absorbed shortwave radiation or downwelling longwave from the atmosphere above the surface, ...
