DIABATIC EFFECTS IN A MULTI-LAYER MODEL OF THE LOWER TROPOSPHERE

Abstract

The heating of the atmosphere by a warm underlying surface and by latent heat of condensation are included in a multi-layer, quasi-geostrophic model of the atmosphere. Attention is focused on the lower troposphere by means of a vertical coordinate. Such a transformation places all significant levels in the model at and below 500 mb. To simulate conditions in the region above 500 mb a modeling approximation on the vertical velocity profile is employed. The barotropic vorticity equation is used at 500 mb. The amount of heating and its vertical distribution are governed in the model by macro-scale parameters. The changes of the surface air temperature are carried in the computations and lead to the generation of fronts along the Atlantic coastline. (Author)
