Описание слайда:
SURFACE LAYER State of the surface layer has a significant impact on vegetable and animal kingdoms, on the activity and state of humanity as a whole, and on individual people. All kind of exchange between surface and the atmosphere come about through the surface layer. (heat, momentum, water vapor fluxes go through it) Processes within the surface layer are different from all other layers of the atmosphere.

Описание слайда:
Some characteristics of the surface layer Surface layer (SL) is greatly influenced by the underlying surface. The latter supplies the SL with heat, water vapor, and admixtures and here the air currents experience the friction effect. Meteorological parameters experience variations with time and altitude that are much stronger than in the rest of the atmosphere. Inversions are frequent phenomena in the surface layer. The most important process in the surface layer is EDDY MIXING.
