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.
The symbol highlighted in yellow (in the diagram above) is known as a Wind Barb. The wind barb indicates the wind direction and wind speed. Wind barbs point in the direction from which the wind is blowing. In the case of the diagram below, the orientation of the wind barb indicates winds from the Northeast. The term easterly means that the winds are from the east. In the example above, the winds are out of the northeast, or northeasterly.
