- Abstract
- Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed by Durst more than 30 years ago for well-developed extratropical storms. When put in terms of dynamic pressure, these higher gust factors suggest increases in qust loads of as much as 20 percent. More data will be needed to establish the probability distribution of hurricane gust factors and to discern any significant differences for locations within and outside of the hurricane eyewall.
