What does a wind vane measure?

• A. Wind Speed
• B. Wind Direction
• C. Air Pressure
• D. Precipitation

Answer: (B)

A wind vane is designed to show the direction the wind is coming from. It turns so that it points into the wind, letting you read the wind’s origin on a compass (like from the north, south, east, or west). This is different from devices that measure how fast the air is moving, which is done by an anemometer. Air pressure is measured by a barometer, and precipitation is tracked by a rain gauge or weather radar. So the wind vane’s job is specifically to indicate wind direction.
