An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
A short burst of high speed wind is termed a wind gust; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval by 10 knots (19 km/h; 12 mph) for periods of seconds. A squall is an increase of the wind speed above a certain threshold, which lasts for a minute or more.
Detailed summary of current weather observations for the local area, consisting of sky condition; actual and apparent temperature (heat index or wind chill values when applicable), and other pertinent data (wind speed/direction/gusts; dew point (1999–2000 and 2003–2022); barometric pressure; humidity; cloud ceiling (1999–2000) and ...
"The threat for damaging winds has ended, but wind gusts of 40 mph will remain possible for the next several hours," according to the National Weather Service. The warning is in effect until 7 a.m ...
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 ...
A variety of models exist for gusts [3] but only two, the Dryden and von Kármán models, are generally used for continuous gusts in flight dynamics applications. [2] [4] Both of these models define gusts in terms of power spectral densities for the linear and angular velocity components parameterized by turbulence length scales and intensities.
Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclonic flow. In the low levels of the troposphere, outflow radiates from thunderstorms in the form of a wedge of rain-cooled air, which is visible as a thin rope-like cloud on weather satellite imagery or a fine line on weather radar ...
ASHEVILLE - A wind advisory is in effect for the Asheville area until midnight Dec. 18, with northwest winds of 20 to 30 mph and gusts up to 50 mph possible, according to a 3 p.m. update from the ...
