Temperature Distributions without Abel Inversion

Applied Spectroscopy, 1968
One of the classical problems of the serious spectroscopist is the determination of the temperature distribution in an arc, or other source, from observations which necessarily involve light emitted by atoms along lines through the arc.

THE ANTARCTIC TEMPERATURE INVERSION

International Journal of Climatology, 1996
In the interior of the Antarctic ice sheet the surface temperature inversion averages over 25°C in the winter months. The negative buoyancy of the near-surface air drives the katabatic windflow, which has important consequences for the climate of Antarctica.

Temperature inversion symmetry in the Casimir effect

Physical Review D, 1989
The finite-temperature Casimir effect between parallel plates has a simple symmetry under temperature inversion. With symmetric boundary conditions the ordinary, zero-temperature Casimir energy is directly related to the Stefan-Boltzmann energy of thermal radiation.

Inversion temperatures and molecular interactions

Physica A: Statistical Mechanics and its Applications, 1998
Abstract Three different types of inversion temperatures are discussed. Their relationships to the second virial coefficient are explored with the intermolecular interactions. A modified hard-sphere system is introduced to present these phenomena with elementary calculus.

Waking up to temperature inversions

Physics Today, 2018
When cool air near the ground is trapped beneath a layer of warmer air, pollution can reach unhealthful levels.

Temperature inversions in geothermal systems

Geoexploration, 1973
Abstract Temperature inversions have been observed in deep boreholes in a number of geothermal areas. An elementary investigation indicates that the observed inversions may be manifestations of temperature disequilibria around fractures or permeable horizons where the thermal or flow conditions have changed recently.

Inverse bremsstrahlung and temperature relaxation in moderately coupled two-temperature plasmas

Physical Review E, 2004
The balance equation for the energy in moderately coupled two-temperature plasmas, in the presence of an external radiation field, is derived and analyzed. The analysis is based on the Singwi-Tosi-Land-Sjolander closure assumption. The different terms in the derived equation are identified as the rate of collisional energy absorption from the external ...

Temperature Inversion by Convective Cooling

Nature, 1949
MOST physicists are familiar with Prof. R. W. Wood's beautiful experiment1 on the anomalous dispersion of sodium vapour. In the form in which the experiment is carried out by students in this Department, the sodium pellets are distributed evenly over about five inches in the middle part of a steel tube roughly twenty inches long and of diameter one ...

Interpretation of inverse acclimation to temperature

Zeitschrift f�r Vergleichende Physiologie, 1970
In kidney of goldfish acclimated to 5, 15 and 25° C the peroxisomal enzyme peroxidase and the peroxisomal and cytoplasmic matrix enzyme catalase showed inverse (Precht type 5) acclimation. Peroxisomal D-amino acid oxidase and lysosomal acid phosphatase were unchanged in activity (Precht type 4).

Evaporation: Local quasimelting, pseudotunneling, and temperature inversion

Physical Review Letters, 1990
I map evaporation onto thermodynamic phase diagram. I demonstrate that when temperature increases, the evaporation rate may decrease, have a maximum and minimum, and change almost discontinuously. Some of these features are in agreement with recent data on the escape of two-dimensional electrons from a bulk helium surface; the others call for new ...
