A cyclone is any mass of air that spirals around a low pressure center. It is an organized collection of thunderstorms embedded in a swirling mass of air. In general, both typhoons and hurricanes are tropical cyclones but differ in their locations. The difference between hurricane and typhoon is that tropical cyclones in the west Pacific are called Typhoons and those in the Atlantic and east Pacific Ocean are called Hurricanes. It's the longitude that matters.
In the northern Indian Ocean, they're called severe cyclonic storms. In the southwestern Indian Ocean, they're just tropical cyclones. To be classified as a hurricane, typhoon, or cyclone, a storm must reach wind speeds of at least 74 miles per hour (119 kilometers per hour). If a hurricane's winds reach speeds of 111 miles per hour (179 kilometers per hour), it is upgraded to an intense hurricane.
