Which tool measures wind direction at a weather station?

• A. Anemometer
• B. Pyranometer
• C. Thermistor
• D. Wind Vane

Answer: (D)

The tool that measures wind direction at a weather station is the wind vane. A wind vane consists of a rotating arm that aligns itself with the direction from which the wind is blowing. The position of the arm indicates the wind direction, typically represented in cardinal directions (e.g., north, south, east, west). This is critical in meteorological observations as understanding wind direction can provide valuable insights into local weather patterns and conditions. The other tools mentioned serve different purposes. An anemometer measures wind speed rather than direction, while a pyranometer measures solar radiation. A thermistor is used for measuring temperature variations. Each of these instruments plays a vital role in meteorology, but for tracking wind direction specifically, the wind vane is the appropriate choice.
