An anemometer will be used to measure the speed of the wind.
<u>Explanation:
</u>
An anemometer is a simple device used to measure the speed of the wind by most meteorologists. The structure of this device is simple as it has three or sometimes four cups attached using horizontal strips made up of steel to a vertical rod.
As the wind blows over the cups, the cups are pushed by the wind making them move. Hence, the vertical rod moves as the wind blows. The revolutions of the vertical rod for a specific time are counted and averaged in order to determine the speed of the wind.
