Hurricane Sandy

Hurricane Sandy lasted from October 22, 2012 until November 2, 2012. It struck some areas in the Caribbean including Bermuda, the Bahamas, the Greater Antilles, the eastern coast of the U.S. including Delaware, Maryland, Virginia, Pennsylvania, New Jersey, New York, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, Maine, and then some parts of eastern Canada. The hurricane originated from a tropical wave in warm ocean waters. Hurricane Sandy was drawn westward by an unusual bend in the jet stream. This jet stream bended northward over eastern North America. This change is caused by the presence of a strong high-pressured cell, called a blocking high, that stops moving over Greenland and any eastward movement of storms behind the blocking high slows down substantially. Then a cold air mass with a low pressure center approached the hurricane’s warmer counterclockwise wind field, the winds circulated around the low pressure centers of the cold air mass and of Hurricane Sandy began to mix. This interaction pulled part of the cold air mass to the south of the hurricane and turned the jet stream separating the two systems westward, which drew Hurricane Sandy toward the New Jersey coast After the cold air mixed with the warm air of the hurricane, both systems came together. This merging caused the hurricane to become a extratropical cyclone, renamed by the National Hurricane Center as the Post-Tropical Cyclone Sandy, but referred to as Superstorm Sandy by meteorologists and newscasters. Hurricane Sandy killed over 200 people, about 80 deaths in the Caribbean and the rest happening in the United States. There was $315 million worth of damage in the Caribbean and $62 billion worth of damage in the U.S.
