Cyclones

What is a cyclone?

A large-scale air mass that rotates around a strong center of low atmospheric pressure.

What are cyclones known as in the North Atlantic and Eastern Pacific?

Hurricanes

What are cyclones known as in the Northwest Pacific?

Typhoons

What conditions are required for cyclone formation?

Warm ocean waters (at least 26.5°C), a pre-existing atmospheric disturbance, high humidity, and low vertical wind shear.

How does warm ocean water contribute to cyclone formation?

It provides the necessary heat and moisture to fuel the storm.

What is the role of low vertical wind shear in cyclone development?

It allows the storm's central vortex to remain intact.

What causes the rotation in cyclones?

The Coriolis effect, which deflects winds due to the Earth's rotation.

What are the main hazards associated with cyclones?

Strong winds, heavy rainfall, storm surges, and flooding
