Wind profile power law
The wind profile power law is a relationship between the wind speeds at one height, and those at another. == Definition == The wind profile power law relationship is u u r = ( z z r ) α {\displaystyle {\frac {u}{u_{r}}}={\bigg (}{\frac {z}{z_{r}}}{\bigg )}^{\alpha }} where u {\displaystyle u} is the wind speed (in metres per second) at height z {\displaystyle z} (in metres), and u r {\displaystyle u_{r}} is the known wind speed at a reference height z r {\displaystyle z_{r}} .
