โœฆ Synopsis

Observations near the BAO tower site have suggested a roughness length of about 0.01 m. Wind profiles from the tower yield values between 0.04 and 0.30 m. We now analyze fluctuations ofvertical velocity at 10 m, and get intermediate values, differing with wind direction. Thus, inferred za values increase systematically with height.

Cross-spectra between horizontal wind components at different levels ofthe Boulder Atmospheric Observatory (BAO) tower lead to the following conclusions: (1) Davenport's hypothesis is satisfied that coherence decays exponentially with the ratio of vertical separation to horizontal wave length, at l
