This small-scale QBO experiment is very interesting

http://www.gfd-dennou.org/library/gfd_exp/exp_e/exp/bo/1/res.htm

The geometry of the setup doesn't match the real QBO at all, yet the results appear to agree with the solution to the primitive equations for a rotating cylinder with a periodic latitudinal forcing. Watch the membrane -- as it pulsates up-and-down the transverse oscillations keep pace. When the membrane amplitude gets bigger gradually the velocity covers a longer swing. That's because the inertial volume can keep up with it.
