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 ...
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 ...
"The 2024 Atlantic hurricane season has now generated 127 ACE (Accumulated Cyclone Energy), officially meeting NOAA's definition of an above-normal season," Klotzbach said on X Wednesday.
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 ...
It also had the highest accumulated cyclone energy since Hurricane John in 1994. [21] Around the same time, Tropical Storm Ileana paralleled the southwestern coast of Mexico, bringing heavy rainfall to the region. [22] Forming in mid-August, Hurricane Lane became the first Category 5 hurricane to form during the year. [19]

In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones).
