From Wikipedia, the free encyclopedia
This is the page for calculating the Accumulated cyclone energy for the 2017 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
2017
=
∑
v
m
a
x
2
10
4
,
{\displaystyle {\text{ACE}}_{2017}=\sum _{}^{}{\frac {{v_{\mathrm {max} }}^{2}}{10^{4}}},}
where v max is estimated sustained wind speed in knots.
Since the ACE calculation method uses data from six-hour intervals, the value for a particular tropical storm is dependent upon the starting time. The operational advisories from NOAA 's National Hurricane Center (NHC) typically begin at 3 UTC, 9 UTC, 15 UTC or 21 UTC, while NHC's Best Track reports and the Colorado State University list typically begin at 0 UTC, 6 UTC, 12 UTC, or 18 UTC.
