Similarity methods to derive turbulence quantities and mixed-layer depth from SODAR measurements in the convective boundary layer: A review
TL;DR: In this article, a brief review of similarity methods which have been developed to calculate turbulence parameters and mixed-layer depth from SODAR measurements is made, where a variety of parametric relations valid in the convective boundary layer are surveyed.

Flux-Profile Relationships in the Atmospheric Surface Layer
TL;DR: In this article, the free constants in several interpolation formulas can be adjusted to give excellent fits to the wind and temperature gradient data, and the behavior of the gradients under neutral conditions is unusual, however, and indicates that von Karman's constant is ∼0.35, rather than 0.40 as usually assumed, and that the ratio of eddy diffusivities for heat and momentum at neutrality is ∼1.0.

The Mathematical Representation of Wind Speed and Temperature Profiles in the Unstable Atmospheric Surface Layer
TL;DR: In this article, analytical expressions which specify non-dimensionalized wind speed and potential temperature gradients as functions of stability are integrated with Swinhank's wind and temperature profiles measured at Kerang, Australia.

TL;DR: A detailed review of developments in atmospheric acoustics of the last decade is given in this paper, which includes new ways to use refractive effects, studies of phase and amplitude fluctuations during propagation of sound along a path, nonlinear effects near high-powered acoustic antennas, problems related to noise, insights into large-scale atmospheric processes gained from infrasound, applications dependent on the Doppler frequency shift, and hybrid devices using both acoustic and electromagnetic waves.

The Birth of “CAT” and Microscale Turbulence
TL;DR: In this paper, a 2m radar image was used to study the life cycle of clear air turbulence and showed the amplification of unstable Kelvin-Helmholtz (KH) waves, the development of roll vortices, their breaking and resulting turbulence.

Acoustic sounding of the lower troposphere
TL;DR: In this article, an acoustic sounding experiment is described in which pulses of acoustic energy were directed upwards and reflected from inhomogeneities in the temperature structure of the lower troposphere to obtain a continuous record of their height, movement, and vertical distribution.
