1982 Atlantic hurricane season
The 1982 Atlantic hurricane season officially began on June 1, 1982 and lasted until November 30, 1982, and was a below average season. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. Only six storms formed during this hurricane season: five named storms (this was the record for the smallest number of named cyclones in the Atlantic basin since naming began in 1950, until the following year (1983) when only 4 named storms formed) and an unnamed subtropical storm (no subtropical storms were named between 1974 and 2001). The season only produced two hurricanes (record low since 1944) one of which reached major hurricane status. The season started early with Hurricane Alberto forming on the first day of the season. Alberto threatened the Southwestern Florida coast as a tropical storm, causing twenty-three fatalities in Cuba. The next storm, a subtropical storm, formed in June and affected the same area as Alberto, causing $10 million in damage.
Tropical Storm Beryl formed on August 28, after a quiet July in the open Atlantic Ocean. Beryl grazed Cape Verde, killing 3 people. Tropical Depression Three formed just behind Beryl, tracking east and north of the Caribbean sea in early September. Soon after the dissipation of Beryl, Tropical Storm Chris formed in the Gulf of Mexico on September 9. Chris stayed as a weak storm, making landfall near Sabine Pass, Texas and dissipated over land on September 13. Hurricane Debby was the next storm and the strongest of the season. The formative stage of Debby produced rainfall in Puerto Rico and soon strengthened into a Category 4 Major Hurricane. Debby passed by Newfoundland on September 18 and merged with a non-tropical low on September 20. In mid-September, Tropical Depression Six formed west of Africa, and tracked west-northwest, dissipating before reaching the Leeward Islands on September 20. Its remnant thunderstorm activity continued moving west-northwest, forming Tropical Depression Seven which moved near Bermuda on September 25 before dissipating offshore Nova Scotia. The final storm of the season, Tropical Storm Ernesto, was the shortest lasting storm of the season and stayed out to sea, dissipating on October 2.
==Season summary==
The season was very inactive because of strong vertical wind shear due to stronger than normal westerly winds aloft.〔Gilbert B. Clark (1983). (Atlantic Hurricane Season of 1982. ) National Hurricane Center. Retrieved on May 23, 2008.〕 The wind shear was contributed by a variety of factors including a strong El Niño. Vertical wind shear was strong enough to disrupt convection in areas of disturbed weather so they could not develop further. The El Niño which affected this hurricane season extended into the 1983 Atlantic hurricane season.〔William S. Kessler (1999). (Southern Oscillation Index. ) University of Washington. Retrieved on May 23, 2008.〕 Higher than average values of African mineral dust during the most active portion of the hurricane season could have also suppressed tropical cyclone activity.
The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 32, which is classified as "below normal". ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Although officially, subtropical cyclones are excluded from the total, the figure above includes periods when storms were in a subtropical phase.
