台风、飓风其实都是热带气旋。根据世界气象组织的定义,中心风力一般达到12级以上、风速达到每秒32.7米的热带气旋均可称为台风或飓风。区别在于,发生在西北太平洋及南海上的热带气旋是我们熟知的台风,而发生在东北太平洋和大西洋上的称之为飓风。

-Cyclone, typhoon, hurricane.

All of these names are used around the world to describe the most powerful storm known to man.

Hurricanes are unpredictable but scientists have a through understanding of how hurricanes form and sustain their power.

In the Atlantic Ocean, hurricane season peaks during the late summer months when tropical waters are the warmest.

Hurricanes form from a cluster of thunderstorms that suck up the warm, moist air and move it high into Earth's atmosphere.

The warm air is then converted into energy that powers the hurricane's circular winds.

These winds spin around a low-pressure center called the eye.

Which can provide a 20 to 30 mile radius of eerie calm.

Encircling it is the eye wall, a towering ring of clouds with some of the fastest wind-speeds of the hurricane.

Surrounding the eye wall are curved bands of clouds.
