A STUDY OF ATMOSPHERIC FRONTOGENESIS WITH THE PRIMITIVE EQUATIONS.

Abstract

The deformation of an unstable baroclinic wave as a result of mean horizontal wind shear is studied with the use of a five-layer primitive equation model. Two basic wind profiles were tested: (1) uniform zonal flow, (2) jet type zonal flow. The jet profile produced a cold front and a warm front, with the warm front being the more intense. The uniform zonal flow produced a cold front. The cold fronts were produced by horizontal shearing deformation fields and the warm front was produced by horizontal stretching deformation fields. The formation of the warm front was also enhanced by strong horizontal convergence. The occlusion process was not observed in the experiments. (Author)
