Wind speed - Wikipedia
网页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 temperature. Wind speed is now commonly measured with an anemometer.

Beaufort scale - Wikipedia
网页The Beaufort scale / ˈ b oʊ f ər t / is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
What exactly is wind velocity - Earth Science Stack Exchange
网页2014年8月23日 · See my answer about wind and you'll see that we have equations that relate fluid velocity to factors like pressure gradients, friction, coriolis force, advection, etc. We could control for these and neglect everything except the pressure gradient within a wind tunnel, and in this wind tunnel with known pressure differences we could derive the ...
Wind Speed - Earthdata
网页2023年5月30日 · Wind Speed. Ratio of the distance covered by the air to the time taken to cover it. The instantaneous speed corresponds to the case of an infinitely small time interval. The mean speed corresponds to the case of a finite time interval. It is one component of wind velocity, the other being wind direction).
Wind Velocity - an overview | ScienceDirect Topics
网页Wind velocity refers to the speed at which the wind is moving in the atmosphere, which is influenced by the height from the ground according to a specific mathematical function. AI generated definition based on: Cold Regions Science and Technology, 2013
Average Wind Speeds - Map Viewer | NOAA Climate.gov
网页By examining the maps, you can identify months of unusually high or low wind speeds, or check the U-wind and V-wind components to look for changes in wind direction. View maps of average monthly wind speed and direction for …
Beaufort Wind Scale - National Weather Service
网页Beaufort Wind Scale. One of the first scales to estimate wind speeds and the effects was created by Britain's Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12.
Wind Velocity - an overview | ScienceDirect Topics
网页The nondimensional wind velocity is derived by averaging the velocity ratios for same reference wind direction for U T > 4 m/s. The number of investigations for the same reference wind direction is 1 to 4 runs for the period before construction, and 2 to 7 runs for the period after construction.
