TL;DR: The surface boundary condition is an essential aspect of an atmospheric model as it controls the surface fluxes of momentum, heat and moisture into the atmosphere as mentioned in this paper, which can be kept constant to a reasonable degree of approximation in short and medium range forecasts.
Abstract: The surface boundary condition is an essential aspect of an atmospheric model as it controls the surface fluxes of momentum, heat and moisture into the atmosphere. The ocean represents a relatively simple boundary condition with a slowly varying sea surface temperature which can be kept constant to a reasonable degree of approximation in short and medium range forecasts. Although there are uncertainties in air/sea transfer over the ocean, current formulations are probably accurate within 20% (see e.g. Beljaars 1997), which is very good compared to the situation over land.
