Wind pressures are positive on the windward side of a structure and negative on the leeward side. Infrequent wind gusts can cause poorly designed suspension bridges to sway. When wind gusts are at a similar frequency to the swaying of the bridge, the bridge can be destroyed more easily, such as what occurred with the Tacoma Narrows Bridge in ...
Wind gust speeds during Storm Abigail in November 2015 Sound of wind blowing in a pine forest at around 25 m/sec, with gust alterations. A wind gust or just gust is a brief, sudden increase in the wind speed. It usually lasts for less than 20 seconds, briefer than a squall, which lasts minutes. A gust is followed by a lull (or slackening) in ...
An even more vicious Santa Ana setup happened in early December 2011, with a peak gust of 97 mph at Whitaker Peak, winds commonly found in a Category 2 hurricane. These devastating winds toppled ...
Wind damage swath extending for more than 400 miles (640 km) Wind gusts of at least 58 miles per hour (26 m/s; 50 kn) along most of its length; Several, well-separated 75 miles per hour (34 m/s; 65 kn) or greater gusts; Prior to January 11, 2022, the definition for a derecho was: [12] Wind damage swath extending for more than 240 mi (390 km)
The apparent wind on the sail creates a total aerodynamic force, which may be resolved into drag—the force component in the direction of the apparent wind—and lift—the force component normal (90°) to the apparent wind. Depending on the alignment of the sail with the apparent wind, lift or drag may be the predominant propulsive component.
A record-breaking wind gust of 97 mph (156 km/h) was observed at George Bush Intercontinental Airport, surpassing the previous record of 82 mph (132 km/h) recorded during Hurricane Ike in 2008. [45] The aftermath left approximately 324,000 customers without power and caused extensive damage to CenterPoint Energy's equipment and infrastructure. [46]
[3] [failed verification] As they form in areas of minimal vertical wind shear, [4] the thunderstorm's rainfall creates a moist and relatively cool outflow boundary which undercuts the storm's low level inflow, and quickly causes dissipation. Waterspouts, small hail, and strong wind gusts can occur in association with these thunderstorms. [5]
The fastest wind speed not related to tornadoes ever recorded was during the passage of Tropical Cyclone Olivia on 10 April 1996: an automatic weather station on Barrow Island, Australia, registered a maximum wind gust of 113.3 m/s (408 km/h; 253 mph; 220.2 kn; 372 ft/s) [6] [7] The wind gust was evaluated by the WMO Evaluation Panel, who found ...
