Turbulence Models and the Synthesis of Random Fields for Acoustic Wave Propagation Calculations
Abstract
A comprehensive set of equations is derived for correlations and spectra of atmospheric turbulence, useful for wave propagation calculations and other applications. Three basic turbulence models are considered: (1) the Gaussian, (2) von Karman, and (3) Kolmogorov models. Two extended forms of the von Karman model are also described: the Mann model for a shear driven atmospheric surface layer, and the Hunt/Graham/Wilson model for a convective boundary layer. A new method for synthesizing random fields from an inhomogeneous spectral model, called the generalized random phase method, is described and applied to the various turbulence models.
