Does water really drain the opposite direction in the Southern Hemisphere?

The water drains counter-clockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere — just the opposite of what it should be doing according to the Coriolis effect. Also, objects need to be much further away from the equator for the Coriolis force to have any effect on them.

Why does water rotation down a drain?

The Coriolis force tends to make things on the surface of the object to spiral a certain direction. As the earth rotates, this motion causes everything on the surface to experience the Coriolis force, including the water in your sink.

Do hurricanes always spin the same direction?

In fact, tropical cyclones — the general name for the storms called typhoons, hurricanes or cyclones in different parts of the world — always spin counterclockwise in the Northern Hemisphere, and spin in the opposite direction in the Southern Hemisphere.

Why does water swirl down a bathtub drain?

This effect of the Earth’s rotation on water is called the Coriolis effect. They say that water in the tub sometimes swirls in the opposite direction when drained. The reason behind this, they say, is that even a very slight disturbance can overcome the Coriolis effect and start the rotation in the opposite direction.

Do toilets drain different in the Southern Hemisphere?

Can you actually use a flushing toilet to figure out whether you are in the Northern or in the Southern Hemisphere? Sadly, you cannot, because toilets tend to angle the jets that pass water into the bowl to drive the direction of draining water.

Why does water spin the other way in Australia?

“The Coriolis force accounts for why cyclones are counterclockwise-rotating storms in the Northern Hemisphere, but rotate clockwise in the Southern Hemisphere. The effects of the rotation of the earth are, of course, much more pronounced when the circulation covers a larger area than would occur inside your bathtub.

Do toilets spin in different directions?

Sadly, you cannot, because toilets tend to angle the jets that pass water into the bowl to drive the direction of draining water.

Does toilet water spin backwards in southern hemisphere?

Likewise, the rotation of the earth gives rise to an effect that tends to accelerate draining water in a clockwise direction in the Northern hemisphere and counterclockwise in the Southern.

Does water empty down a drain hole anti-clockwise in the northern hemisphere?

DOES WATER EMPTY down a drain hole anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere? The answer is – kind of, and sometimes. As a cyclone moves away from the equator, it spins clockwise in the Southern Hemisphere (and anti-clockwise in the Northern Hemisphere), a movement caused by the so-called Coriolis force.

Which direction does water swirl down a drain?

Water swirling down a drain does not always go a certain direction. You can get the same sink to swirl water clockwise one minute and counter-clockwise the next. This misunderstanding has its basis in a very real effect: the Coriolis force.

Does the Earth’s rotation affect the direction of draining water?

This question would seem to be one of simple physics, and yet it continues to engender sharp disagreements. The main problem here is the division between theory and practice: whereas in principle the earth’s rotation could affect the direction of draining water, in the real world that effect is probably swamped by other, less uniform influences.

Does water always swirl in the northern hemisphere?

Seriously. As you can see from videos like this one, some tub-watchers out there insist that water always swirls one direction in the Northern Hemisphere and the opposite direction in the Southern Hemisphere. That argument sounds plausible, especially when the well-known Coriolis effect is invoked (more on that later).
