Home > Shopping Tools > Weather Station Glossary of Terms > wind vane (definition) A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing.
Traditional weather vanes are made up of only a few parts: a vane, a mast, directionals, and an ornament. The vane is usually arrow-shaped, and like an arrow, has a front tip and a back tail.. When the wind blows, it pushes the tail (which has a larger surface area) until it is out of its path.
