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 ...
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 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]
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 typically began to weaken immediately following and sometimes even prior to landfall as they lose the sea fueled heat engine and friction slows the winds. However, under some circumstances, tropical or subtropical cyclones may maintain or even increase their intensity for several hours in what is known as the brown ocean ...
Various charts can be examined to check the characteristics of a cold-core system with height, such as the 700 millibars (20.67 inHg) chart, which is at about 10,000 feet (3,048 meters) altitude. Cyclone phase diagrams are used to tell whether a cyclone is tropical, subtropical, or extratropical. [36]
This true-color image of the storms was made from observations collected by alternating passes of the Aqua and Terra satellites. The cyclones pictured are (west to east) Gerry, Hape, Isha, and Fiona of the 2003 Southwest Indian cyclone season. Terra satellite passed over this area in the morning, moving east to west, and contributing the first ...
