The accumulated cyclone energy (ACE) index for the 2008 Pacific hurricane season as calculated by Colorado State University using data from the National Hurricane Center was 83.8 units. [ nb 1 ] [ 8 ] Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed.
The Eastern Pacific database was originally compiled at the NHC during 1976 to help with the initialization with two tropical cyclone forecast models. Initially, tracks for the Central Pacific region and tracks for tropical depressions that did not develop into tropical storms or hurricanes were not included within the database.
The NHC official forecast is light blue, while the storm's actual track is the white line over Florida. The Automated Tropical Cyclone Forecasting System (ATCF) is a piece of software originally developed to run on a personal computer for the Joint Typhoon Warning Center (JTWC) in 1988, [1] and the National Hurricane Center (NHC) in 1990.
2008 Pacific hurricane season summary map. The 2008 Pacific hurricane season was a near average season which produced seventeen named storms, though most were rather weak and short-lived. Only seven hurricanes formed and two major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific ...
Over the past two decades, the National Hurricane Center’s one- to three-day track forecast errors have diminished by 75%, with reductions of about 60% at four- and five-day lead times.
The first dynamical hurricane track forecast model, the Sanders Barotropic Tropical Cyclone Track Prediction Model (SANBAR), [9] was introduced in 1970 and was used by the National Hurricane Center as part of its operational track guidance through 1989. It was based on a simplified set of atmospheric dynamical equations (the equivalent ...
