Atmospheric Turbulence Measurement System
SPIE Proceedings, 1985Since the summer of 1983, Georgia Tech and NOAA have been engaged in a program whose purpose is to measure, the effects of atmospheric turbulence on the propagation of millimeter waves (MMW). Five different measurement sessions have been conducted, and observations have been made in clear air, rain, fog, and snow at frequencies of 116, 118, 142, 173 ...

The Structure of Atmospheric Turbulence
Theory of Probability & Its Applications, 1958Theoretical 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.

Holography through the Atmospheric Turbulence
1972It is well known that the velocity of propagation of an e.m. wave in the vacuum is c = 3 108 m/sec.

Spectrum of Atmospheric Turbulence
Nature, 1951DR. E. C. S. MEGAW1 opens his valuable contribution to this subject with a challenging remark. He says, “knowledge of the average properties of turbulence in the free atmosphere is almost totally lacking”. Actually, so many meteorologists have published observations that it would be impossible here to give an adequate list of them. As long ago as 1926,

Atmospheric Turbulence and Diffusion
1951The Nature of Turbulent Flow. A particle in a stream of fluid can never follow a perfectly smooth path because of minute random disturbances arising from the molecular structure of the fluid (Brownian motion), but observation shows that, in certain circumstances, oscillations appear in the path which are much too large to be ascribed to molecular ...

Intermittent of Atmospheric Turbulence
Journal of the Atmospheric Sciences, 1989Abstract Dimensionless structure functions such as kurtosis of the velocity gradients are computed from aircraft data for a variety of atmospheric situations in order to characterize the intermittency of the turbulence. It is necessary to distinguish between small scale intermittency of the velocity gradients organized by the individual main eddies and
