Turbulent mixing theory
applied to radio scattering (1956)
Author:
Silverman, Richard A
Publisher: New York: Courant Institute of
Mathematical Sciences, New York University
Excerpt: "Recently, both
Gallet and Villars and Weisskopf have identified turbulent mixing of
refractive index inhomogeneities or gradients as the fluctuation
mechanism primarily responsible for the scattering of radio waves by
the
troposphere and ionosphere. In each of these papers, a heuristic
theory of turbulent mixing is proposed. However, there is also available
a statistical theory of turbulent mixD.ng developed by Obukhoff in 1949.
This paper is concerned
with the application of Obukhoff 's theory to
the radio scattering problem."
