Thermal Structures in the Lowest Layers of the Atmosphere

Abstract

An analysis has been made of a number of records of simultaneous fluctuations of temperature at four heights. The results show that the correlation between temperatures at two heights is greatest when the records are displaced relatively to each other, so that earlier points in the upper record are considered together with later points in the lower, by an amount depending on the mean wind speed difference between the two heights. The correlation increases with height relatively to what would be expected in a locally isotropic turbulence.
