On Correlations between Fields of Temperature, Small Gas Impurities, and Wind in the Surface Layer of the Atmosphere

Abstract

In a number of studies, including our studies performed at the Institute of Atmospheric Physics, Russian Academy of Sciences, stable correlations have been found between scalar fields of the surface layer (fields of temperature and concentrations of small gas impurities—ozone and water vapor), as well as correlations between these scalars and wind speed. This article shows that the correlations of scalars can be understood on the basis of the hypothesis of similarity of surfaces with equal concentrations of impurities and isothermal surfaces, and that temperature maps explain, at a qualitative level, the correlations of temperature and speed. The unique low-inertia devices developed for pulsed measurements of the density of ozone and water vapor are described. Experiments with synchronous registration of temperature, humidity, and ozone, which showed a high correlation of the above scalar fields, and experiments with the vertically multipoint synchronous registration of temperature, which made it possible to construct maps of sections of isothermal surfaces with a vertical plane along the wind direction, are considered.
