From Wikipedia, the free encyclopedia
This is the page for calculating the Accumulated cyclone energy for the 2018 Atlantic 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,
ACE
=
∑
v
m
a
x
2

,
{\displaystyle {\text{ACE}}=\sum _{}^{}{\frac {{v_{\mathrm {max} }}^{2}}{10^{4}}},}
where v max is estimated sustained wind speed in knots.
