Cup anemometer definition
Category: Environmental Condition - Wind
Problem
What is the definition of the cup anemometer wind speed? How does it differ from hub wind speed, for instance?
Solution
The cup anemometer wind speed is the magnitude of the resultant wind speed in the horizontal plane at hub height, therefore corresponds with the “resultant horizontal wind speed” in the wind data at the hub height location. The hub wind speed is the resultant magnitude of all 3 directions of wind at hub height.
