A typhoon is a giant, rotating storm with winds of at least 119 kilometers per hour (74 miles per hour) that forms over warm tropical waters in the northwestern Pacific Ocean.
It is the exact same weather phenomenon as a hurricane or a cyclone; the only difference is the geographic location where the storm occurs.
Geographic Terminology
Term | Region |
|---|---|
Typhoon | Northwestern Pacific Ocean (e.g., Hong Kong, Japan, Philippines, China) |
Hurricane | North Atlantic Ocean and Northeastern Pacific Ocean (e.g., USA, Caribbean) |
Cyclone | South Pacific Ocean and Indian Ocean (e.g., Australia, India, Madagascar) |
How a Typhoon Forms
Warm Ocean Water: The sea surface temperature must be at least 26.5°C (80°F) to fuel the storm.
Moist Air: High humidity in the lower atmosphere creates heavy clouds and thunderstorms.
Coriolis Effect: The Earth's rotation forces the rising warm air to spin, creating a vortex.
Low Wind Shear: Weak winds at high altitudes allow the storm's structure to grow vertically without breaking apart.
Main Hazards of a Typhoon
Destructive Winds: High-velocity winds can destroy buildings, uproot trees, and knock down power lines.
Storm Surge: The storm pushes a massive wall of seawater onto the coast, causing severe coastal flooding.
Torrential Rain: Extreme rainfall over a short period triggers widespread inland flooding and deadly landslides.
