What type of disturbance does Effects of Hurricane Matthew in Haiti and have in common?
Effects of Hurricane Matthew in Haiti Hurricane Matthew struck southwestern Haiti near Les Anglais on October 4, 2016, leaving widespread damage in the impoverished nation. Matthew was a late-season Category 5 hurricane on the Saffir–Simpson scale, having formed in the southeastern Caribbean on September 28. The hurricane weakened to Category 4 before making landfall near Les Anglais on October 4, at which time the National Hurricane Center estimated maximum sustained winds of 240 km/h (150 mph). This made it the strongest storm to hit the nation since Hurricane Cleo in 1964, and the third strongest Haitian landfall on record. Hurricane-force winds – 74 mph or greater – affected about 1.125 million people in the country. The Haitian government assessed the death toll at 546, although other sources reported more than three times that figure.
Central dense overcast 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. Locating the center within the CDO can be a problem for strong tropical storms and with systems of minimal hurricane strength 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.
