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.
Both the central dense overcast and embedded eye pattern utilize the size of the CDO. The CDO pattern intensities start at T2.5, equivalent to minimal tropical storm intensity (40 miles per hour (64 km/h)). The shape of the central dense overcast is also considered. The farther the center is tucked into the CDO, the stronger it is deemed. [11]
In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or ...
central dense overcast (CDO) The large, centralized, contiguous area of thunderstorms surrounding the rotational center of a strong tropical or subtropical cyclone. When a cyclone reaches sufficient intensity, a distinguishable eye may develop within the CDO. The strongest winds and heaviest rainfall are usually found beneath the coldest cloud ...
Central Dense Overcast A dense mass of clouds that covers and eyewall or the most tightly curved inner bands of a tropical cyclone. [1] Central North Pacific Basin The region north of the Equator between 140W and the International Dateline. The Central Pacific Hurricane Center (CPHC) in Honolulu, Hawaii is responsible for tracking tropical ...
“Satellite images show an expanding central dense overcast feature, and recent microwave images indicate that a partial eyewall has formed.” Here’s what you need to know about Hurricane Beryl .
Rainfall is found to be heaviest in tropical cyclone's inner core, whether it be the eyewall or central dense overcast, within a degree latitude of the center, with lesser amounts farther away from the center. [5] Most of the rainfall in tropical cyclones is concentrated within its radius of gale-force (34 knots/39 mph; 63 km/h) winds. [6]
The "feels like" temperature, generally, is a more accurate description of what the human body will experience when stepping outside.
