Abstract

 The weather condition in the middle latitudes is controlled by westerly wind and high and low pressures, and these phenomena are interpreted as the baroclinic instability waves. A rotating fluid experiment by Fultz and Hide are known as the typical laboratory experiments of baroclinic instability waves. In this study, we introduced a new equipment having the unique feature characterized by the heated and cooled bottom. By this condition, 4-6 zonal wave numbers were observed and flow field were dynamically changed with time. At the same time, it was observed that the vorticity on center changed with baroclinic waves with time.
