Ioke: ACE of 81

[phantom power]

This is part of my previous post, but I thought it deserved it's own topic, on the grounds that it blew my mind:
PS: here is a link to a definition of ACE:

Hurricane Ioke (a.k.a. Super Typhoon Ioke after it crossed the Date Line) was the strongest hurricane ever recorded in the Central Pacific, and remained at Category 4 or 5 strength longer than any tropical cyclone on record. Ioke spent 36 (33 consecutive) 6-hourly reports at that strength. The previous records were held by 2004's Hurricane Ivan with 33 (32 consecutive) and 1997's Typhoon Paka with 27 (25 consecutive) 6-hourly reports. The Accumulated Cyclone Energy (ACE) for this one storm was about 81--higher than the ACE index of 79 accumulated by all the tropical cyclones in the Atlantic 2006 hurricane season.
