What does ACE mean in meteorology?

What does ACE stand for in weather?

The measure of overall activity used by NOAA is called the Accumulated Cyclone Energy (ACE) index. The ACE index is essentially a wind energy index, defined as the sum of the squares of the estimated 6-hourly maximum sustained wind speed (knots) for all named systems while they are at least tropical storm strength.

How is ACE calculated?

Accumulated cyclone energy (ACE) is a metric used by various agencies to express the energy used by a tropical cyclone during its lifetime. The calculation takes a tropical cyclone’s maximum sustained winds every six hours and multiplies it by itself to generate the values.

How do you calculate the ace of a hurricane?

The formula for ACE. Accumulated cyclone energy (ACE) is a unit of measurement of the activity of a hurricane season. It is calculated for a storm by taking the storm’s wind speed in knots, squaring it, dividing it by 10000, then summing these values for each advisory.

Which hurricane had the highest ACE?

The highest ever ACE index calculated for a single storm in the North Atlantic Basin was Hurricane Ivan in 2004, with a generated ACE of 70.4. The next two closest North Atlantic tropical storms were Hurricane Irma in 2017, with an ACE of 64.9, and Hurricane Isabel in 2003, with an ACE of 63.3.
