1. Typoon
Typoon blows to 16~97km/h, has 1600km in diameter, moves about 40km/h, and takes a few weeks to extinct. Typoon not only makes wind, but also disgorges heavy rain that causes floods. Vortex of typoon blows counterclockwise on the northern hemisphere, and its center is called "the eye of a typhoon".
2.Hurrican
Hurricanes develop over ocean water warmer than 26.5 °Celsius and heat and moisture from the ocean forms the basis of this type of storm. Thus, hurricanes weaken rapidly over land and over cold waters, which cannot provide enough heat or moisture to sustain this storm. The low pressure centers of hurricanes are known as the "eye" and are warmer than their surrounding areas. The eye is surrounded by strong winds and rain and this area is called the "eye wall". Hurricanes have no fronts. The hurricane season peaks from the middle of August to late October in the Atlantic Ocean.
The only difference between a hurricane and a typhoon is the location where the storm occurs.
Hurricanes,typhoons are the same weather phenomenon; we just use different names for these storms in different places. In the Atlantic and Northeast Pacific, the term “hurricane” is used. The same type of disturbance in the Northwest Pacific is called a “typhoon”.
