Paper Abstract

Analytical models of the spatial power spectral of temperature fluctuations and refractive index fluctuations that feature a 'bump' at high wave numbers have recently been developed. These models, based on the effects of intermittency, evolved through an approximation for the intermittency effect that led to a two-term modification of the standard Tatarski spectra models. This paper examines the intermittency correction with experimental data and standard spectra models. Specifically, more accurate approximations to the intermittency effect that lead to a four-term modification of the Tatarski model are developed. A comparison between these two modifications of the standard Tatarski spectrum is discussed in the context of theoretical studies concerning optical propagation through atmospheric turbulence.
