However, in a rotating environment things don't work in the same way. As the pressure difference begins to move water along the pressure gradient, the Coriolis force changes the direction of the flow. It ends up with the flow in which the pressure gradient balances with the Coriolis force. This is called a geostrophic flow. In this model of the atmosphere, if the distribution of temperature is concentric, then the resulting geostrophic flow will also be concentric. In this situation, the flow of water in the upper layers is the same direction as the rotating table, like the westerlies which we see in the earth's atmosphere. In this photo, the flow of water is made visible by liquid crystal capsules, and temperature is represented by different colors.
