Talk:2023 Atlantic hurricane season/ACE calcs

This is the page for calculating the Accumulated cyclone energy for the 2023 Atlantic hurricane season. If any storms of a season happen to cross years, the storm's ACE counts for the previous year.

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.
