Hurricane, typhoon, cyclone — people often think these are different kinds of storms. They're not. They're the same weather phenomenon, a tropical cyclone, called different names depending on where in the world it forms.
Same storm, different name
- Hurricane — the name used in the North Atlantic and the Northeast and Central Pacific (the Americas).
- Typhoon — the same storm in the Northwest Pacific (around Asia — Japan, the Philippines, China).
- Cyclone — the name in the South Pacific and Indian Ocean (around Australia, India, and East Africa).
All three are tropical cyclones: warm-core, low-pressure systems with organized rotation and sustained winds of at least 74 mph. The physics is identical; only the label changes with the ocean basin.
Which way do they spin?
There's one real difference, and it isn't the name — it's the spin. In the Northern Hemisphere tropical cyclones rotate counterclockwise; in the Southern Hemisphere they rotate clockwise. That's the Coriolis effect from the Earth's rotation — and it's also why these storms can't form right on the equator, where that effect is too weak.
Are typhoons stronger than hurricanes?
Not inherently. The Northwest Pacific tends to produce more storms, and some of the most intense on Earth, because it's a vast, warm basin with room for storms to grow — but a hurricane and a typhoon of the same wind speed are exactly as dangerous. The strongest tropical cyclones (winds above roughly 150 mph) are sometimes called “super typhoons” in the Pacific.
Bottom line
Hurricane, typhoon, and cyclone are three regional names for one thing. If you understand how a hurricane works, you already understand typhoons and cyclones — the danger and the science travel under every name.
