TLDR
In this paper, it is shown that even weak wind shear conditions, as they occur in the normal planetary boundary layer, can affect flight safety, especially when the aircraft's flight performance is adversely affected by an engine failure.About:

Coping with wake vortex
TL;DR: In this paper, the authors proposed a more flexible separation procedure taking into account the actual weather situation and the parameters of the individual aircraft pairing, which can be achieved by wake vortex avoidance using prediction systems for the wake vortex development and movement.

Dynamics of Atmospheric Flight
TL;DR: In this article, the dynamics of atmospheric flight, with special reference to the stability and control of airplanes, are discussed. But the authors focus on human pilots and handling qualities and flight in turbulence, with numerical examples for a jet transport.

Turbulent wind flow over a low hill
P. S. Jackson,J. C. R. Hunt +1 more
TL;DR: In this article, an analytical solution for the flow of an adiabatic turbulent boundary layer on a uniformly rough surface over a two-dimensional hump with small curvature was presented for the limit L/y 0 → ∞ when h/L 2k2/ln(δ/y0) where L and h are the characteristic length and height of the hump, y0 the roughness length of the surface and δ the thickness of the boundary layer.

Boundary Layer Wind Maxima and Their Significance for the Growth of Nocturnal Inversions
TL;DR: The supergeostrophic wind speeds suggest that an inertia oscillation is induced when the constraint imposed by the daytime mixing is released by the initiation of an inversion at about the time of sunset as mentioned in this paper.

Adiabatic atmospheric boundary layers: A review and analysis of data from the period 1880–1972
TL;DR: In this paper, a review and analysis of the meteorological literature on fully developed adiabatic boundary layers is presented, particularly with respect to quantifying the power indices and turbulence intensities appropriate to rougher terrains, and the variation of the turbulence length scales with height and terrain type.

Structure of low-level jet streams ahead of mid-latitude cold fronts
Keith A. Browning,C. W. Pardoe +1 more
TL;DR: In this paper, it is shown that the line convection can be regarded as part of a mesoscale right-hand corkscrew circulation within the low-level jet, which is characterized by very strong cyclonic shear and is fed by frictional convergence of air from beneath the jet core within the lowest 100 mb.
