Wind direction is the direction in which the wind is blowing, i.e., where it is coming from. It is usually expressed in terms of geographic position, such as easterly, southerly, and so on. Measurement of wind direction is usually carried out using instruments such as wind vane or anemometer, and the common wind vane is wind bag, wind ball, wind cone, etc.. Measurement of wind direction is important for weather forecasting, aviation, navigation, environmental monitoring and other fields.

Wind speed is the speed of wind movement, usually expressed in meters per second, kilometers per hour and other units. The measurement of wind speed is usually carried out using instruments such as anemometers, and common anemometers include hot-wire anemometers, rotor anemometers, and ultrasonic anemometers. The measurement of wind speed is important for weather forecasting, aviation, navigation, architectural design and other fields.

Wind direction and wind speed are two important parameters for describing wind, and they are usually used together to characterize wind.

Surface Wind Speed: refers to the wind speed about 10 meters above the ground

Wind Direction: refers to the direction from which the wind is blowing, with 0° in the north direction, and positive in the clockwise direction
