Wind Sock

A wind sock is a type of meteorological instrument used to measure the direction and speed of the wind. It is typically made of a conical-shaped fabric tube that is open at both ends. The larger end of the wind sock is attached to a pole or mast, while the smaller end is left open to allow the wind to flow through.

The wind sock is designed in such a way that it aligns itself with the direction of the wind. This allows observers to visually determine the wind direction by observing the orientation of the wind sock. The wind speed can also be estimated by observing the extent to which the wind sock is inflated or extended.

Wind socks are commonly used at airports, helipads, and other locations where accurate wind information is crucial for safe operations. They are also used in meteorological stations, research facilities, and other areas where wind data is collected and analyzed.

In the supply group "Instruments And Laboratory Equipment," wind socks are classified under the supply class "Meteorological Instruments And Apparatus." This class includes various instruments and apparatus used for measuring and studying weather conditions, such as barometers, thermometers, anemometers, and rain gauges.
