Does this help explain those El Nimoy years when the weather is funny?
The Coriolis effect is of course quite real, but it is relatively weak wrt many other forces which can overwhelm it in small settings that we can easily observe - like the built-in swirling jets in a toilet bowl (much more dependent on manufacture than hemisphere) or slight imperfections in aiming or differences in pond bottoms (if, for example, Bruce were to try and observe the Ekman effect in a Horizontally aerated pond).
