Season Summary
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 an 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.
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. Subtropical cyclones are excluded from the total.
