Typhoon

A powerful tropical cyclone that forms over warm ocean waters in the Western Pacific Ocean

A small storm system that forms over land

A snowstorm that occurs in polar regions

A tornado that forms in the Midwest United States

Because the region experiences many typhoons.

Because typhoons rarely occur there.

Because typhoons have no impact on communities.

Because the region controls global weather.

Hurricanes form in the Atlantic or Northeast Pacific, cyclones in the Indian Ocean, and typhoons in the Northwest Pacific.

Hurricanes form in the Indian Ocean, cyclones in the Atlantic, and typhoons in the Arctic.

All three form only in the Atlantic Ocean.

Typhoons form in the Atlantic, hurricanes in the Northwest Pacific, and cyclones in the Indian Ocean.

Cool air sinks over warm ocean water, creating calm winds → clouds disperse → a vortex forms from cold fronts.

Warm, moist air rises from the ocean surface → air begins to rotate due to wind shear and the Earth’s rotation → the rotation strengthens, forming a violent spiraling system.

Dry air from land moves over the ocean → condensation rapidly cools the sea surface → a spiral cloud tower forms instantly.

Ocean water cools to below 20°C → winds slow down → clouds compress into a rotating storm.
