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.
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.
The relative sizes of Typhoon Tip, Cyclone Tracy, and the Contiguous United States. While hypercanes can be smaller than Cyclone Tracy, the largest hypercanes could even exceed Typhoon Tip in size. In order to form a hypercane, according to Emanuel's hypothetical model, the ocean temperature would have to be at least 49 °C (120 °F).
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 cyclone went on to hit northern Mozambique on Sunday, but the full extent of the impact was not clear. Internet monitor NetBlocks said on X that heavy rain and winds had damaged power and ...
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 storm, or cyclone, is essentially a giant spinning vacuum in the atmosphere. When a storm's central pressure drops 0.71 of an inch of mercury inches (24 millibars) or more in 24 hours or less ...
