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.

Micro-structured magnetic atmospheres

Solar Physics, 1996
Asymmetrical Stokes profiles are produced if the photospheric magnetic and velocity fields are structured on scales smaller than the mean-free-path of the photons. Here we put forward a compact analytical expression for the radiative transfer equation in this case.

Thermal Structure of Uranus' Atmosphere

Icarus, 1999
Application of a radiative-convective equilibrium model to the thermal structure of Uranus' atmosphere evaluates the role of hazes in the planet's stratospheric energy budget and places a lower limit on the internal energy flux. The model is constrained by Voyager and post-Voyager observations of the vertical aerosol and radiative active gas profiles ...

Structure of the Atmosphere

2011
Atmospheric pressure and density decrease quasi-exponentially with increasing altitude in accordance with the barometric law. Figure 3.1 presents an idealized vertical temperature profile of the atmosphere and the nomenclature adopted by international convention to identify different altitude regimes, which are distinguished by the prevailing sign of ...

Structure of the Venus atmosphere

Planetary and Space Science, 2007
Abstract The structure of the Venus atmosphere is discussed. The data obtained in the 1980s by the last Soviet missions to Venus: orbiters Venera 15, 16 and the entry probes and balloons of Vega 1 and 2 are compared with the Venus International Reference Atmosphere (VIRA) model. VIRA is based on the data of the extensive space investigations of Venus

Structure of the atmosphere

1999
Under normal environmental conditions, the electromagnetic radiation emitted by radiating sources only reaches a receptor after having passed through the atmosphere. But note that the presence of this material medium is not required for propagation: unlike waves whose natures are different such as mechanical vibrational waves or thermal waves, and ...

STRUCTURE OF ATMOSPHERIC TURBULENCE

Journal of Meteorology, 1953
Abstract Experimental data on the energy spectra, correlation coefficients and energy isotropy of atmospheric turbulence at low elevations are presented. It is shown that the very simple formulas derived with the aid of Kolmogoroff's Similarity Hypothesis are remarkably consistent with the experimental evidence of this and other research projects.

THE COMPOSITION AND STRUCTURE OF THE TERRESTRIAL ATMOSPHERE

1963
Abstract : After a generel description of the various regions of the terrestrial atmospbere, an analysis of physical conditions leading to the knowledge of the heterosphere is given. Molecular dissociation and diffusion in the lower thermosphere are introduced to determine the concentration of various constituents (N2, O2, O, N, He, H).
