WindspeedHellmann | R Documentation |
For a wind speed at given height, returns a scaled wind speed at some different height. Often used to obtain wind speed at hub height.
WindspeedHellmann(v0, HH = 100, refHeight = 10, alpha = 1 / 7)
v0 |
wind speed (in meters per second) at reference height. |
HH |
the height (in meters) at which wind speed is desired. |
refHeight |
reference height (in meters). The height at which the actual wind speed (v0) was measured. |
alpha |
power law parameter. Usually set to 1/7 for onshore sites. |
This function simply implements
v = v_0 (\frac{HH}{refHeight})^{α}
WindspeedHellmann
returns a wind speed (in meters per second) at the desired height.

WindspeedLog
for a different way to scale wind speeds to heights.
WindspeedLog(v0 = 6, HH = 80, z0 = 0.1, refHeight = 20) WindspeedHellmann(v0 = 6, HH = 80, refHeight = 20)
