Some further thoughts on the spectrum of gustiness in strong winds
AbstractThis paper discusses the well known Von Karman formula for the spectrum of the longitudinal component of atmospheric turbulence, and its known deficiencies in fitting data measured in the layer nearest to the ground.An alternative approach is suggested, which is based on the Von Karman formula but provides corrections enabling measured data to be fitted. Modified formulae for the spectra of the turbulence velocity components are derived which contain the necessary systematic variation in spectrum shape with height above ground level.
