Estimating Refractive Index Spectra in Regions of Clear Air Turbulence

Abstract

Estimates of the spectrum of refractivity fluctuations to be expected in regions of clear turbulence are shown for scales in the inertial subrange. Based on the complete analysis by Atlas et al., it is concluded that radar detection of clear air turbulence with current technology is unlikely for all but inversion conditions. However, the present analysis can be used to provide consistent estimates for particular environmental conditions.
