Abstract : The evolution of general circulation patterns was studied by means of two-level quasi-geostrophic models. Four different experiments were performed and compared to an earlier experiment in which the basic initial flow was assumed to be constant at each pressure level and the Rossby parameter did not depend on the latitude. The assumptions made in the different runs were respectively: (1) Maximum zonal flow at the central latitude. (2) Maximum zonal flow south of the central latitude. (3) Constant zonal flow at each pressure level and a latitudinal variation of the Rossby parameter. (4) Maximum zonal flow south of the central latitude and a latitudinal variation of the Rossby parameter. The evolving distribution of various field-variables was investigated and compared to the actual distributions observed in the atmosphere. The most significant results were obtained in the third run. Specifically only in this case did the asymmetrical distributions of the field-variables around the central latitude tend to develop in the direction of the asymmetries observed in the atmosphere.
