Wind vanes or wind socks.
The anemometer measures wind speed. A weather vane tells wind direction.
An Anemeter is a device used by (usually) Scientist to measure wind speeds.
An anemometer or windmeter is the device that measures wind speed. They are usually divided into those that measure the wind's speed and it's pressure. The first known anemometer was described in 1450 by Leon Battista Alberti.anemometer.
225 degrees means wind direction is South/West indicating the direction from which the wind is coming. Like 0 or 360 degrees means North direction.
A 'wind vane' measures direction
A wind vane.........
The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
Weather vane is for direction and anemometer is for speed
The anemometer measures wind speed, and the wind-vane measures its direction. Those two measurements combine to indicate the wind velocity. Wind force depends on the method and device used to capture wind-power, or the shape and size of the structure against which the wind blows. For any single device or structure, the force of the wind against it is closely related to the wind's speed and direction.
compass points. Usually a wind vane which swings into line with the direction of the wind.
Speed: anemometer.Direction: wind- or weather-vane, which for accurate readings would havesome form of angle sensor.The two are sometimes used together as an aerovane.Another common device is the "wind sock," an orange cloth cone used to indicatecrosswinds at airports and heliports. Within a range of speeds, the cone indicateswind direction, and it gives a general idea of the wind speed from the inflation ofthe cone by the wind.
