The only difference between a hurricane and a typhoon is the location where the storm occurs. 飓风和台风之间的唯一区别就是风暴发生的位置不同。 A close-up satellite image of Hurricane Isabel taken on Sept. 15, 2003.

A tropical cyclone is a generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation. 飓风和台风是同一种天气现象：热带气旋。热带气旋是气象学家用来描述一个有规律旋转着的云团和雷暴气象系统的通用术语。它们形成于热带或亚热带水域，且具有封闭的低水平环流。 The weakest tropical cyclones are called tropical depressions. If a depression intensifies such that its maximum sustained winds reach 39 miles per hour, the tropical cyclone becomes a tropical storm. Once a tropical cyclone reaches maximum sustained winds of 74 miles per hour or higher, it is then classified as a hurricane, typhoon, or tropical cyclone, depending upon where the storm originates in the world. |
