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]
Tropical cyclone naming – once a tropical cyclone reaches winds of 34 kt (39 mph), a name would be given to that specific cyclone. Names are usually given by their respective RSMCs when the cyclone reaches tropical storm status. History of tropical cyclone naming – history of tropical cyclone naming from the late 18th century onward.
A tropical cyclone tracking chart is used by those within hurricane-threatened areas to track tropical cyclones worldwide. In the north Atlantic basin, they are known as hurricane tracking charts . New tropical cyclone information is available at least every six hours in the Northern Hemisphere and at least every twelve hours in the Southern ...
In the peak of Atlantic hurricane season, words matter. And using the right ones at the right time can be the difference between alerting of a far-out rotating storm system to a nearer full-blown ...
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]
A warning of 1-minute sustained surface winds of 48 kn (55 mph or 88 km/h) or greater, either predicted or occurring, not directly associated with tropical cyclones. [1] Strike strike zone diagram For any particular location, a hurricane strike occurs if that location passes within the hurricane's strike circle, a circle of 125 nmi diameter ...
Tropical cyclones portal This category covers the history and meteorology of specific tropical cyclones , including hurricanes and typhoons. Meteorological causes, phenomenology, and physical principles of tropical cyclones are covered in category:tropical cyclone meteorology .
Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.
