This is the page for calculating the Accumulated cyclone energy for the 2022 Pacific hurricane season. If any storms of a season happen to cross years, the storm's ACE counts for the previous year.^[1]

The ACE is calculated by summing the squares of the estimated maximum sustained velocity of every active tropical storm (wind speed 35 knots or higher), at six-hour intervals. The numbers are divided by 10,000 to make them more manageable. The unit of ACE is 10⁴ kt², and for use as an index the unit is assumed. Thus,

{\text{ACE}}=\sum _{}^{}{\frac {{v_{\mathrm {max} }}^{2}}{10^{4}}},

where v_max is estimated sustained wind speed in knots.
