Tropical cyclone - Wikipedia
A tropical cyclone is a rapidly rotating storm system with a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls.
Typhoon - Wikipedia
A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least 119 km/h (74 mph). [1] . This region is referred to as the Northwestern Pacific Basin, [2] accounting for almost one third of the world's tropical cyclones.

What is a Hurricane, Typhoon, or Tropical Cyclone?
The terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone". A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).

Oct 19, 2023 · Tropical cyclones with an organized system of clouds, and thunderstorms with a defined circulation and maximum sustained winds of 38 mph (61 km/h) or less, are called "tropical depressions". Once the tropical cyclone reaches winds of at least 39 mph (63 km/h), they are typically called a "tropical storm" and ass
Hurricanes, Typhoons, and Cyclones | Smithsonian Ocean
What’s the difference between a hurricane, a typhoon and a cyclone? The short answer is that there is none. They are all organized storm systems that form over warm ocean waters, rotate around areas of low pressure, and have wind speeds of at least 74 mph (119 km per hour).
Tropical Cyclone Introduction | National Oceanic and …
A tropical cyclone is a warm-core low pressure system, without any front attached, that develops over the tropical or subtropical waters and has an organized circulation. These include hurricanes and typhoons. There are several favorable environmental conditions that must be in place before a tropical cyclone can form. They are:
