What instrument does the weather station use to observe the wind?
Wind observation generally includes wind speed and direction.
The traditional anemometer generally includes two parts: a horizontal wind vane and a wind cup. Among them, the wind cup can determine the speed of horizontal wind by its rotating speed, while the wind vane can determine the horizontal wind direction by its pointing direction.
The more advanced anemometer is the three-dimensional ultrasonic anemometer, and the direction and magnitude of the three-dimensional wind vector can be directly determined by ultrasonic measurement.
