Coriolis Effect

[JustSia]

The direction of rotation of cyclones is different in Northern and Southern hemispheres. And since coriolis effect around the equator is equal/close to zero, if say an unprecedented happened and the cyclone crossed the equator what would happen to it, would it just die down? If you did try and recreate the drain effect in the large enough environment what would it look like at the equator and yes, I do know the water would go down the drain.

Also is there a direct relation between coriolis effect and telluric currents?

No effect, the effect you describe is very slight and the existing momentum of the cyclone will easily overcome any slight anti rotation. It is weakest at the equator anyway.

Water goes doen the sink in the opposite direction in northern and southern hemisphere if left to it's own devices, however try stiring the water in the opposite direction with your finger and you will seem you can counter the entire Earth coriolis effect with your finger.

Enough of this 'water spins down the plug hole the opposite way in Australia' nonsense.

The Coriolis force affects weather systems because they are hundreds of km across and last for days. The effect on a bowl of water that is 1m across and has been under the influence of the force for a few minutes is quite literally too small to measure. The SLIGHTEST residual motion in the water or the SLIGHTEST lack of symmetry in either the bowl or the drain pipe will swamp the Coriolis force completely.

I've no idea why children are taught this rubbish.

Tim, I know, that's why I was asking this question in terms of cyclones. But am still none the wiser.
