Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a measure used by the National Oceanic and Atmospheric Administration (NOAA) to express the activity of individual tropical cyclones and entire tropical cyclone seasons, particularly the North Atlantic hurricane season. It uses an approximation of the energy used by a tropical system over its lifetime and is calculated every six-hour period. The ACE of a season is the sum of the ACEs for each storm and takes into account the number, strength, and duration of all the tropical storms in the season.

Famous quotes containing the words accumulated and/or energy:
“Chinese were born ... with an accumulated wisdom, a natural sophistication, an intelligent naivete, and unless they were transplanted too young, these qualities ripened in them.... If ever I am homesick for China, now that I am home in my own country, it is when I discover here no philosophy. Our people have opinions and creeds and prejudices and ideas but as yet no philosophy.”
—Pearl S. Buck (1892–1973)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.”
—George F. Will (b. 1941)
