The years 1995 to 2000 experienced the highest level of North Atlantic hurricane activity in the reliable record. Compared with the generally low activity of the previous 24 years (1971 to 1994), the past 6 years have seen a doubling of overall activity for the whole basin, a 2.5-fold increase in major hurricanes (>/=50 meters per second), and a fivefold… (More)
The 1995 Atlantic hurricane season was a year of near-record hurricane activity with a total of 19 named storms (average is 9.3 for the base period 1950–90) and 11 hurricanes (average is 5.8), which persisted for a total of 121 named storm days (average is 46.6) and 60 hurricane days (average is 23.9), respectively. There were five intense (or major)… (More)
1. Overview The North Atlantic hurricane season officially runs from June-November. An average season produces 10 tropical storms (TS), 6 hurricanes (H), and 2 major hurricanes (MH) [defined as maximum sustained wind speeds at or above 100 kts, and measured by categories 3-5 on the Saffir-Simpson scale (Simpson 1974)]. In 2003 the Atlantic basin was… (More)
1. Overview The 2005 Atlantic hurricane season broke many tropical cyclone records. The season featured a record 27 tropical storms (TS), a record 15 hurricanes (H), a record four category-5 hurricanes, a record estimated Accumulated Cyclone Energy (ACE) index (Bell et al. 2000) of 285% of the median (Fig. 1), and an ACE contribution of 131% of the median… (More)
Fig. 1. Atlantic tropical storm and hurricane tracks during 2008. Shading indicates storm strength, with green indicating tropical depression, yellow indicating tropical storm (TS), red indicating hurricane (H, Cat. 1-2) and purple indicating major hurricane (MH, Cat. 3-5).
Using the hurricane weather research and forecasting experimental modeling system (HWRFx), researchers examined the impact of increased model resolution on system performance in forecasting a select sample of tropical cyclones from the 2005 and 2007 hurricane seasons.
