In general, hurricanes are steered by global winds. The clockwise rotation (in the Northern Hemisphere) of air associated with high-pressure systems often cause hurricanes to stray from their initially east-to-west movement and curve northward.

How does a hurricane die?

Explanation: One of the driving forces of a hurricane is heat energy in oceanic surface waters. Warm water evaporates more quickly, and warm air rises. If it moves onto land it loses that warm water source, and so dies down.

What makes a hurricane stronger?

When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes.

What is Coriolis effect caused by?

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.

Why Coriolis force is zero at Equator?

Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object’s path as measured relative to Earth’s surface. The object’s path is straight, that is, there is no Coriolis effect.
