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 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 ...
The storm produced hurricane-force wind gusts and heavy rainfall, causing hundreds of millions of dollars in damage and leaving over 1.8 million residences and businesses without power. Eighteen people were killed, most of whom died of carbon monoxide poisoning in the days following the storm because of improper use of barbecue cookers and ...
When wind gusts harmonize with the frequency of the swaying bridge, the bridge may fail as occurred with the Tacoma Narrows Bridge in 1940. [ 17 ] Hurricane-force winds, caused by individual thunderstorms, thunderstorm complexes, derechos, tornadoes, extratropical cyclones, or tropical cyclones can destroy mobile homes and structurally damage ...
Straight-line winds are common with the gust front of a thunderstorm or originate with a downburst from a thunderstorm. These events can cause considerable damage, even in the absence of a tornado. The winds can gust to 58 m/s (130 mph) [11] and winds of 26 m/s (58 mph) or more can last for more than twenty minutes. [12]
The Enhanced Fujita Scale takes into account the quality of construction and standardizes different kinds of structures. The wind speeds on the original scale were deemed by meteorologists and engineers as being too high, and engineering studies indicated that slower winds than initially estimated cause the respective degrees of damage.

The solar wind is a ubiquitous feature of our solar system. But precisely how the sun generates the solar wind has remained unclear. New observations by the Solar Orbiter spacecraft may provide an ...
