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. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a problem with strong tropical storms and minimal hurricanes as its location can be obscured by the CDO's high cloud canopy. This center location problem can be resolved through the use of microwa

has abstract	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. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a problem with strong tropical storms and minimal hurricanes as its location can be obscured by the CDO's high cloud canopy. This center location problem can be resolved through the use of microwave satellite imagery. After a cyclone strengthens to around hurricane intensity, an eye appears at the center of the CDO, defining its center of low pressure and its cyclonic wind field. Tropical cyclones with changing intensity have more lightning within their CDO than steady state storms. Tracking cloud features within the CDO using frequently updated satellite imagery can also be used to determine a cyclone's intensity. The highest maximum sustained winds within a tropical cyclone, as well as its heaviest rainfall, are usually located under the coldest cloud tops in the CDO.

Localizar o centro dentro do CDO pode ser um problema para fortes tempestades tropicais e com sistemas de força mínima de furacão, pois sua localização pode ser obscurecida pela alta cobertura de nuvens do CDO. Este problema de localização central pode ser resolvido com o uso de imagens de satélite de microondas. Depois que um ciclone se fortalece em torno da intensidade de um furacão, um olho aparece no centro de CDO, definindo o seu centro do baixa pressão e seu campo de vento ciclônico. Os ciclones tropicais com intensidade variável têm mais relâmpagos em seu CDO do que as tempestades de estado estacionário. O rastreamento de recursos de nuvem dentro do CDO usando imagens de satélite frequentemente atualizadas também pode ser usado para determinar a intensidade de um ciclone. Os ventos máximos máximos sustentados em um ciclone tropical, bem como suas chuvas mais pesadas, geralmente estão localizados sob o topo das nuvens mais frias do CDO.
