Extreme winds constitute an important loading condition to all types of above-ground structures and facilities. Extreme winds produce loads on structures as a result of the induced pressures, wind-propelled missiles, atmospheric pressure change, and storm surge effects. Site-specific wind hazard risks vary significantly across the United States, reflecting fundamental differences in topography and local climatology. Extreme wind hazards are generally categorized according to the causative meteorological system as extratropical cyclones, tropical cyclones (hurricanes), tornadoes, thunderstorms, and down-bursts. In addition to these storm systems, topographical features may also result in localized, special wind regions. |
