Turbulence in the Atmosphere

, 2010
Based on his 40+ years of research and teaching, John Wyngaard's textbook is an excellent up-to-date introduction to turbulence in the atmosphere and in engineering flows for advanced students, and a reference work for researchers in the atmospheric sciences. Part I introduces the concepts and equations of turbulence.

Choice of the Model of Atmospheric Turbulence

Applied Optics, 1972
The concept of equivalent models of turbulence is introduced in order to investigate how the theoretical behavior of the structure function of an electromagnetic wave propagating in a given turbulent medium depends on the turbulence model. It is shown that equivalent models may give rise to substantially different structure functions of a wave ...

The Structure of Atmospheric Turbulence

Theory of Probability & Its Applications, 1958
Theoretical and experimental data are given for the statistical characteristics of random fields of wind velocity and turbulent fluctuations of temperature in the lowest layer of the atmosphere. Fluctuations are considered at one and two space time points.

Atmospheric turbulence mitigation based on turbulence extraction

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
A video taken under the influence of atmospheric turbulence suffers from serious distortion caused by the variation of optical refractive index. In order to reduce geometric distortion and time-space-varying blur, and recover both coarse structure and fine details, a novel turbulence extraction based approach for recovering a latent image from an ...

Propagation of Sound in a Turbulent Atmosphere

The Journal of the Acoustical Society of America, 1970
Applying a perturbation technique to the correct form of the equation for the acoustic pressure field in a viscous turbulent atmosphere yields the power spectra for the amplitude and phase fluctuations of a propagating plane wave. The development includes the effects of absorption and removes the restrictions on wavenumber that previously prevented ...

Atmospheric turbulence

Quarterly Journal of the Royal Meteorological Society, 1948
AbstractEvidence which has accumulated shows that the classical theory of atmospheric turbulence which assumes thatKthe coefficient of eddy diffusion is constant with height is inadequate to explain the observed variations of wind and temperature with height.
