Abstract: Data from a boundary-layer experiment conducted over a flat, uniform site in Minnesota provide a clue to the behavior of the low-frequency peak in surface-layer horizontal velocity spectra. This portion of the spectra shows ...

Abstract: Sonic anemometers were installed at four levels on the Cedar Hill television tower and operated for selected periods during three weeks in August 1963. One of the runs covered the entire history of a nocturnal low-level ...

Abstract: The Boulder Atmospheric Observatory (BAO) is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The facility includes a 300 m tower instrumented with ...

Abstract: The paper describes the characteristics of a convective plume and a dust devil from measurements made at 5.66 and 22.6 m above a flat uniform site in Kansas. The velocity fluctuations were measured with a continuous-wave, ...
