Through Atlantic Ocean, Cuba and El Niño–Southern Oscillation

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 hit Sabine Pass, Texas. Hurricane Debby was the next storm and the strongest of the season. The formative stage of Debby produced rainfall in Puerto Rico, causing one death on the island, 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 system and stayed out to sea, dissipating on October 3.

Season summary

The 1982 Atlantic hurricane season officially began on June 1 and ended on November 30. The season was very inactive because of strong vertical wind shear due to stronger than normal westerly winds aloft. The wind shear was contributed by a variety of factors including a very 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. Higher than average values of African mineral dust during the most active portion of the hurricane season could have also suppressed tropical cyclone activity.

Starting in the 1982 season with Hurricane Debby, the Hurricane Hunter Aircraft (also known as P-3s) began running a new mission for NOAA's Hurricane Research Division. The mission was to drop dropsondes that deployed very-low Omega frequency signals. These signals were to estimate the dropsonde's motion compared to the aircraft in certain areas in a storm. The National Oceanic and Atmospheric Administration noted in retrospect that "The P-3s were not optimal for this experiment; nevertheless, the flights added an extra dimension to the art and science of hurricane forecasting", improving the accuracy of tropical cyclone forecast tracks by about 15%.

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 fully tropical storms were in a subtropical phase.
