Many people use the rotation of water down sinks as an example of the Coriolis effect, claiming that it turns different directions in either hemisphere. This is largely known to be false, since water rotates both directions no matter where you are on the globe (or plane, if you like), and differences can often be attributed to the shape of the sink itself.
A better example, that I haven't seen explained, is that of low pressure weather systems.
In the Northern Hemisphere, a low pressure weather system such as a cyclone, will rotate anti-clockwise. The converse will happen in the Southern Hemisphere.
How can this be explained under the FE model?
