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
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

The relative sizes of Typhoon Tip, Cyclone Tracy, and the United States. Larger tropical cyclones have larger rain shields, which can lead to higher rainfall amounts farther from the cyclone's center. [6] This is generally due to the longer time frame rainfall falls at any one spot in a larger system, when compared to a smaller system.
The Fujiwhara effect – which describes the rotation of two storms around each other – is one of meteorology's most exquisite dances. It's most common with tropical cyclones such as typhoons or ...
Typhoon Haiyan (Yolanda) on November 7, 2013, one of the strongest Pacific typhoons ever recorded.. Since 1947, the Joint Typhoon Warning Center (JTWC) has classified all typhoons in the Northwestern Pacific Ocean with wind speeds of at least 130 knots (67 m/s; 150 mph; 240 km/h)—the equivalent of a strong Category 4 on the Saffir–Simpson scale, as super typhoons.
