1. On a particular day, the wind speed is 2 m/s at a height of 10 m. Estimate the wind speed at heights of 100 m and 300 m if the power law exponent on the velocity profile is 0.15 (level ground, little cover). Repeat the estimates for an exponent of 0.4 (urban area).
2. The wind speed over an urban area is 10 m/s at a height of 10 m. Estimate the wind speed at a height of 30 m.
