Accumulated cyclone energy

Accumulated cyclone energy (ACE) is a metric used by various agencies to express the energy used by a tropical cyclone during its lifetime. The calculation takes a tropical cyclone's maximum sustained winds every six hours and multiplies it by itself to generate the values. These values are then added together which become a total for a storm and can either be divided by 10,000 to make them more manageable or added to other totals in order to work out a total for a particular group of storms. The calculation was originally created by William Gray and his associates at Colorado State University as the Hurricane Destruction Potential index, which took each hurricane's maximum sustained winds above 65 kn (120 km/h; 75 mph) and multiplied it by itself every six hours. This index was subsequent
