What is wind direction and speed?

Wind direction refers to the direction of the wind, which is the direction of the wind. Usually expressed by geographical location, such as east wind and south wind. The wind direction is usually measured by instruments such as wind vane or anemometer. Common weather vanes include wind bag, wind ball and wind cone. The measurement of wind direction has important applications in meteorological forecast, aviation, navigation, environmental monitoring and other fields.

Wind speed refers to the speed of wind movement, usually expressed in meters/seconds, kilometers/hours and other units. Wind speed is usually measured by anemometers and other instruments. Common anemometers include hot wire anemometer, rotor anemometer and ultrasonic anemometer. The measurement of wind speed has important applications in meteorological forecast, aviation, navigation, architectural design and other fields.

Wind direction and wind speed are two important parameters to describe wind, and they are usually used together to describe the characteristics of wind.

Data parameter Surface wind speed: refers to the wind speed about 10 meter above the ground.

Wind direction: refers to the direction of the wind, with due north being 0 and clockwise being positive.
