Accumulated cyclone energy is calculated by summing the squares of the estimated maximum sustained velocity of tropical cyclones when wind speeds are at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph) [4] at recorded six-hour intervals. The sums are usually divided by 10,000 to make them more manageable.
The estimated five-day rainfall totals east of the Mississippi River from Sept. 24 to Sept. 29, based on calculations from research meteorologist Ryan Maue. That's enough water to fill about ...
2 Seasons table: proposal for slightly more user-friendly arrangement and corrections
While the number of tropical storms and hurricanes that form each year is important to track, experts say that the Accumulated Cyclone Energy (ACE) index is a more reliable way to quantify the ...

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just ...

English: :Accumulated Cyclone Energy of North Atlantic hurricanes Accumulated Cyclone Energy (ACE) is an index used to measure the activity of a cyclone/hurricane season. It combines the number of hurricane systems, how long they existed and how intense they became.
