The wind has both magnitude and direction. Therefore, wind forecasts include wind speed and direction. The magnitude of wind speed is often expressed by several wind levels. The wind level is determined based on the impact of the wind on objects on the ground. Meteorologically, winds are currently generally divided into thirteen levels (some typhoons are divided into 17 levels): in weather forecasts, terms such as "north wind level 4 to 5" are often heard. Wind force refers to the average wind strength; you hear terms like "gust level 7", gust refers to the wind speed that suddenly increases and decreases, and the wind strength at that time refers to the strength of the high-speed wind. Represented by the wind arrow, it is made of wind direction rods and wind feathers. Wind direction lever: indicates wind directionection of the wind, there are 8 directions. Wind plume: Consists of 3 or 4 dashes and triangles representing a strong wind force, vertically to the right of the end of the wind pole (Northern Hemisphere).

The wind farm anemometer tower data includes: time, wind speed, wind direction, temperature, pressure, etc. For more detailed information, it is recommended to consult Yongheng Communication. The company takes all users into account and pursues the principleof "pragmatism, refinement and sincerity in treating people" to provide users with excellent products and excellent services.
Data from the airspeed tower;
1. 5 min average wind speed, sampled once per second, automatically calculates and records the average wind speed every 5 min, m/s.
2. Hourly Average Wind Speed: Obtain the hourly average wind speed from the 5-minute average wind speed value, m/s.
3. Maximum Wind Speed: The maximum wind speed value sampled every 3 seconds, m/s.
4. WindDirection Sampling: Wind direction and wind speed collected synchronously with wind speed.
5. The wind direction recorded in the wind direction area is the instantaneous sampling value of a certain wind speed in the area. When the wind direction area is divided into 16 par equal parts, each fan-shaped area contains 22.5° and how many degrees can be used to express wind direction.
6. Temperature: Collect samples every 5 minutes and record the ambient temperature of the collection site, ℃.
7. Relative humidity: Collect samples every 5 minutes and record the ambient humidity at the collection site, RH%.
8. Atmospheric pressure: Collect samples every 5 minutes and record the atmospheric pressure at the collection site, hPa. Click to get preferential policy
