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 ...
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]
Latvia's wind capacity grew by 75%, the largest percent increase in 2022. [3] In November 2018, wind power generation in Scotland was higher than the country's electricity consumption during the month. [5] Wind power's share of worldwide electricity usage in 2023 was 7.8%, up from 7.3% from the prior year.
Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h). [ 313 ] 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.
Screenshot of the Global Wind Atlas website (version 2.2) The Global Wind Atlas is a web-based application developed to help policymakers and investors identify potential high-wind areas for wind power generation virtually anywhere in the world, and perform preliminary calculations. It provides free access to data on wind power density and wind ...
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.
In Japan, the island of Yonaguni recorded wind speeds of up to 180 km/h (110 mph). In Indonesia, large waves of up to 2.5 m (8.2 ft) in height affected the Molucca Sea, North Natuna Sea, Natuna Sea, and the areas between the Sitaro Islands and Bitung, and between the Sangihe Islands and Talaud Islands.
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.
