On the evaporation from a lake in warm and dry environment

Abstract

Evaporation suppressed by an inversion can occur over water reservoirs, when air is advected from a dry and warm environment. A proposed model of this process is based on the conservation of heat and moisture, and on the energy balance at the water surface. Under steady state conditions the inversion height, and the turbulent heat and water vapor fluxes are analytically determined. They depend on the travel distance of the air over the water surface, on simple turbulence parameters, on the net radiation at the water surface, and the temperature and moisture distribution over the land. An example is presented for the case of a well mixed environment.
