Hurricanes rotate due to the Coriolis Effect, a product of earth's spin. in the northern hemisphere wind moving toward the Hurricane from the north will be deflected to the west, while wind coming in from the south will be deflected to the east.
It is different for tornadoes as they are too small to be significantly influenced by this effect. Instead what happens is the wind speed and direction change with altitude, a condition called wind shear, this sets some of the air rolling on a horizontal axis. This rolling can then be tilted into a vertical position by a thunderstorm's updraft. The rotation can then tighten and intensify to form a tornado.
The rotation in hurricanes and tornadoes comes fro different sources.
In a hurricane the low pressure draw air inwards across a very broad region. Since earth is spherical, it can be said to be "fatter" (relative to the axis) at latitudes closer to the equator. This means that they have to travel further in the same amount of time as earth rotates, or in other words must move faster. However, air traveling from one latitude to another will resist this change in speed. As a consequence, air drawn into a northern hemisphere from the north will be deflected to the west of the storm, while air drawn in from the south will be deflected to the east, resulting in a counterclockwise rotation. This is called the Coriolis effect.
However, on systems such as tornadoes and individual thunderstorms, which are much smaller than hurricanes, this effect is negligible. The rotation of a tornado comes from the thunderstorm that produces it. If a thunderstorm moves into a condition called wind shear, where the wind speed and direction varies greatly with height, it can cause the rising air within the storm to start rotating. If this rotating storm is strong enough the rotation can tighten into the more intense vortex of a tornado.

What effects causes hurricanes to have their swirl?
Hurricanes swirl due to the Earth's rotation, known as the Coriolis effect. As air moves from high to low pressure in a hurricane, the Coriolis effect causes it to bend, creating the distinctive circular motion. This swirling motion is essential for the development and intensification of hurricanes.
Is it true that hurricanes are classified by three stages in which updrafts of air billow up updrafts and downdrafts swirl the wind up and down then downdrafts cause clouds to come apart?
No. These stages define the life cycle of a thunderstorm, not a hurricane.
Cyclonic low pressure storms of high winds that develop over water are called?
hurricanes
Do hurricanes occur in the Antarctic?
Hurricanes do not typically occur in the Antarctic region. Hurricanes are more common in tropical and subtropical regions where warm ocean waters fuel their development. The unique climate and geography of Antarctica do not provide the necessary conditions for hurricanes to form.
What about hurricanes and tornadoes is true Hurricanes cover a larger area than tornadoes Hurricanes can kill people but tornadoes cannot Hurricanes have strong winds?
Hurricanes cover a larger area than tornadoes. Both hurricanes and tornadoes can be deadly, although hurricanes are more likely to cause widespread destruction due to their larger size and duration. Both hurricanes and tornadoes have strong winds, but hurricanes typically have more sustained, powerful winds over a larger region.
Is the sense hurricanes of the swirl different in the Southern Hemisphere?
Yes, hurricanes and other cyclones in the Northern hemisphere swirl counterclockwise while in the southern hemisphere they swirl clockwise.
What effects causes hurricanes to have their swirl?
Hurricanes swirl due to the Earth's rotation, known as the Coriolis effect. As air moves from high to low pressure in a hurricane, the Coriolis effect causes it to bend, creating the distinctive circular motion. This swirling motion is essential for the development and intensification of hurricanes.
Why does the right bank of a river in the northern hemisphere suffer more erosion on the average than the left bank?
This is caused by Coriolis effect, which also causes the hurricanes in the north hemisphere to swirl counterclockwise.
