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 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 ...
The central dense overcast, or CDO, of a tropical cyclone or strong subtropical cyclone is the large central area of thunderstorms surrounding its circulation center, caused by the formation of its eyewall. It can be round, angular, oval, or irregular in shape. This feature shows up in tropical cyclones of tropical storm or hurricane strength.

Post-tropical cyclones, such as remnant lows, no longer possess tropical quantities through either unfavorable conditions (e.g. increased wind shear) or land interaction. Pacific hurricane – a tropical cyclone that forms west of 100°W to the International Date Line in the Northern Hemisphere. The National Hurricane Center is responsible for ...
