Is a wind sock not used to measure wind?
A wind sock is used to show the direction of the wind.
Wind socks measure the direction of the wind when the wind blows into the open end and the sock points the way the wind is blowing. Wind socks can also measure the strength of the wind. If a wind sock is flapping about gently the wind is only light. If a wind sock sticks out in a straight line the wind is much stronger.
Here are most of the weather tools and what they are used for: Weather balloons measure conditions at high altitudes and are used in forecasting. GPS keep track of the balloons' movements, which allows for the measuring of wind conditions. Barometers measure air pressure and are used to predict storms and rainfall at the surface. Thermometers measure temperature. Hygrometers measure humidity, or moisture content of the air. Anemometer measure wind speed. Wind Sock or Weather…
Wind speed is normally measured by an anemometer, and the direction by a wind vane (weathervane). However, there are combined instruments called aerovanes. Another valuable device for indicating the wind direction is the "wind sock," which is an orange cloth cone used as a vane. The wind sock also provides a very broad indication of the wind speed by observing how the cone is extended by the wind.
There really isn't something to measure the amount of wind, I believe that you are referring to wind speed and direction. The instruments that are used to measure wind speed is the anemometer. Also, for wind direction, we would use a wind vane. You can feel the direction of wind.... I guess humans are like one giant wind vane!
