Sources and Detection of Atmospheric Wind Shear
TLDR
In this article, a range of phenomena producing significant atmospheric wind shears, providing more details on the shears related to thunderstorm gust fronts, are discussed. But the authors focus on the detection of wind shear in the lees of mountains.Abstract:
This paper outlines a range of phenomena producing significant atmospheric wind shears, providing more details on the shears related to thunderstorm gust fronts. A case study from a wintertime Colorado front-range experiment during 1980 documents strong wind gradients that can occur in the lees of mountains. Strengths and weaknesses of some detection methods are discussed, and evaluations of both remote-sensor and in situ sensor approaches for detecting atmospheric wind shear are emphasized.read more

The Boulder Atmospheric Observatory
J. C. Kaimal,J. E. Gaynor +1 more
TL;DR: The Boulder Atmospheric Observatory (BAO) as mentioned in this paper is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors, which includes a 300 m tower instrumented with fast and slow-response sensors, a variety of remote sensing systems, and a real-time processing and display capability that greatly reduces analysis time for scientists working with current or archived data.

Nocturnal low-level jet over a shallow slope
Alan Shapiro,Evgeni Fedorovich +1 more
TL;DR: In this paper, a simple theory is presented for a nocturnal low-level jet (LLJ) over a planar slope, which extends the classical inviscid inertialoscillation model of LLJ to include up-and downslope motion in the boundary layer within a stably stratified environment.

Stability theory for a pair of trailing vortices
TL;DR: In this article, the authors considered the early stages of the formation of a train of vortex rings and found that their stability depends on the products of vortex separation 6 and cutoff distance d times the perturbation wavenumber.
