Geostrophic adjustment — tank experiments In the rotating tank, we will attempt to examine the geostrophic adjustment problem by releasing a cylinder of ﬂuid which is denser or lighter than its surroundings while the tank is rotating. To set this up, you need to ﬁgure out what kind of density diﬀerence is needed to make a deformation radius on the order of 10 cm. The ﬂuid in the tank will be about 10–20 cmdeep. Rotation rate is up to 10 rpm. How much salt to you need to add per amount of water to get a reasonable g � ? Things to do: Estimate the slope of the interface you expect to see. Compare with observations. Estimate the swirl speed. When spun up, remove can vertically Ω Sketch of apparatus Add dyed, salty water to level of water outside Ω
