Annual average timeseries of accumulated hurricane intensities.

Timeseries Plot:
Select this link to get a plot. Plot is taken from the Timesseries Plotting and Analysis webpage.
Calculation Method:
From NOAA's Hurricane Research Division.The ACE is calculated by squaring the maximum sustained surface wind in the system every six hours (knots) and summing it up for the season. It is expressed in 10^4 kt2.
Time Interval: Monthly
Time Coverage: 1948 to 2009
