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 ...
Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h). [ 312 ] A DOW calculation of a subvortice of the 2013 El Reno tornado was estimated in a range of 257–336 mph (414–541 km/h) in 2024.
Sidrap wind farm, Indonesia's first wind power plant, in Sidrap Regency, South Sulawesi. On average, low wind speeds mean that for many locations there is limited scope for large-scale energy generation from wind in Indonesia. Only small (<10 kW) and medium (<100 kW) generators are feasible. [72]
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.
The name "Mawar" means Rose in Indonesia. ... (right side) had a max wind speed of 193 mph (311 km/h) about 400 feet (120 m) above the surface. ... Wikipedia® is a ...
Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
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 wind speed. [1] Generally, winds are least gusty over large water surfaces and most gusty over rough land and near high buildings. [2]
In common usage, wind gradient, more specifically wind speed gradient [1] or wind velocity gradient, [2] or alternatively shear wind, [3] is the vertical component of the gradient of the mean horizontal wind speed in the lower atmosphere. [4] It is the rate of increase of wind strength with unit increase in height above ground level.
