Q) Meteorological measurements on a cloudy day give the following data: Height above ground, Z (m) Wind speed, U (m/s) 1.01 7.470 10.00 11.214 Use this data to estimate the values of the frictional velocity and the aerodynamic roughness length. What would be the expected wind speed at a height of 40m with this representation of the velocity profile? (Answers: U.=0.65, Zo=0.010 m, U40=13.478 m/s)
