GENERAL CIRCULATION EXPERIMENTS WITH A TWO-LEVEL QUASI-GEOSTROPHIC MODEL INCLUDING THE NON-LINEAR INTERACTION BETWEEN A SINGLE WAVE IN THE ZONAL DIRECTION AND THE MEAN FLOW.

Abstract

A long-period forecast is made using a two-level quasi-geostrophic model. The model includes friction and heating which is a linear function of y. The model was further simplified by restricting the disturbance to one wave in the zonal direction. Experiments were performed with two distances between the walls. In the case of the longer separation, a solution with appreciable time fluctuations was obtained with the largest fluctuation being investigated in more detail. The smaller separation revealed a traveling wave of constant amplitude similar to that observed in certain dishpan experiments. (Author)
