Tropical cyclones that occur within the Northern Hemisphere between the anti-meridian and 100°E are officially monitored by the Japan Meteorological Agency (JMA, RSMC Tokyo). [8] Within the region a tropical cyclone is defined to be a non-frontal synoptic scale cyclone originating over tropical or sub-tropical waters, with organized convection ...
The NHC and the Central Pacific Hurricane Center assign tropical cyclone intensities in 5 knot increments, and then convert to mph and km/h with a similar rounding for other reports. So an intensity of 115 kn is rated Category 4, but the conversion to miles per hour (132.3 mph) would round down to 130 mph, making it appear to be a Category 3 storm.
A tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and flooding rain. [45] A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. [45]
The wave can lead to the formation of a tropical cyclone. Tropical disturbance: The system has organized convection and originates in the tropics or subtropics, having a non-frontal migratory ...
A Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the Atlantic Ocean to the north of the equator. They are among the strongest tropical cyclones that can form on Earth, having 1-minute sustained wind speeds of at least 137 knots (254 km/h; 158 mph; 70 m/s).
Within the North Atlantic Ocean, a Category 2 hurricane is a tropical cyclone, that has 1-minute sustained wind speeds of between 83–95 knots (96–109 mph; 154–176 km/h; 43–49 m/s). [1] Since records began in 1851, a total of 246 tropical cyclones have peaked at this intensity.
