 The season 's activity was reflected with an accumulated cyclone energy ( ACE ) rating of 199 , which was above the 1950 @-@ 2000 average of 96 @.@ 1 . ACE is , broadly speaking , a measure of the power of the hurricane multiplied by the length of time it existed , so storms that last a long time , as well as particularly strong hurricanes , have high ACEs . It is only calculated for full advisories on tropical cyclones with winds exceeding 39 mph ( 63 km / h ) , which is tropical storm strength .
