caption_attribution_description: English: A weather station atop a digester at the Feilding, New Zealand Waste Water Treatment Plant.
context_page_description: 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. Note that wind direction is usually almost parallel to isobars, due to Earth's rotation.
  Wind speed affects weather forecasting, aviation and maritime operations, construction projects, growth and metabolism rate of many plant species, and has countless other implications.
  Wind speed is now commonly measured with an anemometer.
