Atmospheric coherent turbulence

Atmospheric and Oceanic Optics, 2012
This paper summarizes results received by authors for last decade on the problem of the atmospheric coherence turbulence. Also shows some new results of the unpublished researches. According to our data the coherent turbulence is the result of the self-organizing non-linear processes in continuous media, including in the atmospheric air.

An Atmospheric Turbulence Probe

IEEE Transactions on Geoscience and Remote Sensing, 1980
In this paper, a complete low-cost atmospheric turbulence probe, capable of measuring temperature, differential temperature, humidity, horizontal wind speed and direction, and vertical wind component is described. Special care has been taken to minimize the probe's weight so that it may be carried easily by a balloon.

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 ...

Zernike polynomials and atmospheric turbulence

, 1976
This paper discusses some general properties of Zernike polynomials, such as their Fourier transforms, integral representations, and derivatives. A Zernike representation of the Kolmogoroff spectrum of turbulence is given that provides a complete ...

Turbulent Diffusion in the Atmosphere

2017
This chapter deals with an approach towards a physical description of the spreading of pollution in a turbulent atmosphere. We may witness this phenomenon quite commonly by, e.g., following the smoke of a chimney or the steam emerging from a power plant.

500  Gb/s free-space optical transmission over strong atmospheric turbulence channels.

Optics Letters, 2016
We experimentally demonstrate a high-spectral-efficiency, large-capacity, featured free-space-optical (FSO) transmission system by using low-density, parity-check (LDPC) coded quadrature phase shift keying (QPSK) combined with orbital angular momentum ...

Influences of atmospheric turbulence effects on the orbital angular momentum spectra of vortex beams

, 2016
We investigate the atmospheric turbulence effects on orbital angular momentum (OAM) spectra of different kinds of vortex beams, including Laguerre–Gaussian (LG) beams and Bessel beams, numerically. We generate the holograms of atmospheric turbulence with

Expressing oceanic turbulence parameters by atmospheric turbulence structure constant.

Applied Optics, 2016
The parameters composing oceanic turbulence are the wavelength, link length, rate of dissipation of kinetic energy per unit mass of fluid, rate of dissipation of mean-squared temperature, Kolmogorov microscale, and the ratio of temperature to salinity ...

Turbulent bursts in the atmosphere

Atmospheric Environment. Part A. General Topics, 1990
Although the spectral description of turbulent flows has provided some valuable clues about pollutant dispersion in the atmosphere, there has been a growing feeling that such a description may be too limited for providing an understanding of the dynamics as detailed phase information is discarded.
