Question

When does a storm become a typhoon

Answer 1

Explanation:

Once a tropical cyclone with hurricane intensity from the Northeast Pacific moves with a westerly component and crosses the 180° longitude line, it enters the Northwest Pacific and becomes a typhoon if it retains its hurricane intensity (sustained winds of 64 knots or more).

Answer 2

They're all the same, officially tropical cyclones. But they just use distinctive terms for a storm in different parts of the world. Hurricane is used in the Atlantic, Caribbean Sea, central and northeast Pacific. They are typhoons in the northwest Pacific.
