  2. Anemometer - Wikipedia

    en.wikipedia.org/wiki/Anemometer

    The air flow past the cups in any horizontal direction turned the shaft at a rate roughly proportional to the wind's speed. Therefore, counting the shaft's revolutions over a set time interval produced a value proportional to the average wind speed for a wide range of speeds. This type of instrument is also called a rotational anemometer.

    Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction

  4. Wind speed - Wikipedia

    en.wikipedia.org/wiki/Wind_speed

    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 ...

    en.wikipedia.org/wiki/Wind_assistance

    In the long jump, Iván Pedroso jumped 8.96 metres in Sestriere, Italy in 1995 to break the world record by one centimetre – however, the result was never accepted due to wind assistance problems. The wind gauge did show a legal tail wind of 1.2 m/s, but this was declared void as someone had been standing in front of the gauge, thereby ...

    en.wikipedia.org/wiki/Meteorological_instrumentation

    A weather station is a facility with instruments and equipment to make observations of atmospheric conditions in order to provide information to make weather forecasts and to study the weather and climate. The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts.

    Direction shown by smoke drift but not by wind vanes 2 Light breeze 4–6 knots 4–7 mph 6–11 km/h 1.6–3.3 m/s 1–2 ft 0.3–0.6 m Small wavelets still short but more pronounced; crests have a glassy appearance but do not break Wind felt on face; leaves rustle; wind vane moved by wind 3 Gentle breeze 7–10 knots 8–12 mph 12–19 km/h
