The 2020 Atlantic hurricane season ranked amongst the top five most powerful seasons in the satellite era, based on Accumulated Cyclone Energy (ACE). That year, the 30 named storms (including 14 hurricanes, of which six major hurricanes) in the basin registered an ACE of 184. Nine out of the ten most extreme seasons in the period happened since 1990, with 2005 leading the ranking with an ACE of 250.
Strongest hurricane seasons in the Atlantic basin from 1966 to 2020, based on Accumulated Cyclone Energy
According to NOAA, "the Accumulated Cyclone Energy (ACE) is an index that combines the numbers of systems, how long they existed and how intense they became. It is calculated by squaring the maximum sustained surface wind in the system every six hours that the cyclone is a Named Storm and summing it up for the season."
Additionally, "beginning in 1966, daily satellite imagery became available at the National Hurricane Center, and thus statistics from this time forward are most complete, and therefore records are divided into the pre-Satellite Era (1851-1965) and the Satellite Era (from 1966-present)".
