As the wind travels north toward the North Pole, it moves over parts of Earth that are rotating progressively more slowly. Since the wind retains its angular momentum, it keeps moving from west to east, overtaking the part of Earth turning more slowly below it.
As a result, the wind appears to bend to the east that is, to the right. This is the Coriolis Effect in action. Wind flowing south from the equator would likewise bend to the east. This effect is responsible for many meteorological and oceanographic phenomena. For instance, due to the Coriolis Effect, hurricanes in the Northern Hemisphere spin in a counterclockwise direction, while hurricanes in the Southern Hemisphere known as cyclones spin in a clockwise direction.
There is an urban legend that water in toilets spins in opposite directions in the Northern and Southern Hemispheres because of the Coriolis Effect. But that isn't true—a toilet bowl is too small for the effect to be observed. Instead, other factors like the shape of the toilet bowl and the direction that the water enters are largely responsible for how the flushing water moves. The Coriolis effect makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.

In the Northern Hemisphere, winds moving north are diverted eastward, and winds moving south are diverted westward. In the Southern Hemisphere, winds traveling toward the equator will move eastward, and winds traveling toward the South Pole will curve west. When these winds collide, they will swirl clockwise in the south, and counterclockwise in the north. A variety of factors influence how hurricanes form. First they require warm water and warm, moist air — abundant in the mid and southern Atlantic Ocean regions.
Warm water evaporates and rises, forming clouds and releasing heat into the air. As the air rises, it leaves an area of low pressure near the surface of the water. If the clouds continue to build up a thunderstorm will form, and that low pressure area can become more intense, drawing more moist air toward it and continuing to intensify the storm.
This is where the Coriolis effect comes in. If you happen to have small solid object that will fit into the water, it makes for a really interesting observation as the spinning vortex will whip that object around the 2 liter as the vortex pushes everything down! Ok, so wind is simply motion of air that is caused by differences in pressure, the earth spins to the right, hurricanes develop over time under the right conditions of warmth, water, and pressure, that are sustained, and if you know the hurricane develops in the south or the north, you can reasonably predict whether it will be spinning clockwise destination Northern Hemisphere from Southern Hemisphere.
So what is all this recent media business on whether Hurricanes are getting worse. Well, it turns out, that climate change suggests that our climate is getting warmer. The basic principle is that since the oceans are getting warmer, then the evaporative movement of water will be forming more storm clouds, which will experience higher pressure differences, which will create faster movement of wind, which will increase wind speeds with circulation motion, which will result in stronger hurricanes.
Water is literally being pushed by the wind over long distances and it piles up onto the shore or in other instances leaves beaches with dry ocean beds. We could talk about this topic forever, but we will start with some basic problem solving. However, if you look at how you theoretically stop them, there are three basic methods:. The basic reason that Hurricanes Spin the way that they do, is that the earth is spinning to the right, and all hurricanes have wind that is being pushed to the right.
It just matters whether the hurricane is traveling to the South or traveling to the North, that causes the hurricane to be Clockwise Destination Northern Hemisphere or CounterClockwise Destination Southern Hemisphere.
