Some aspects of modelling low-level jets

Boundary-Layer Meteorology, 1988
An improved non-stationary two-layer model is presented for the simulation of wind speed maxima in the nocturnal boundary layer. The model is based on the idea of Blackadar (1957), who proposed as forcing mechanism an inertial oscillation of the ageostrophic component of the wind vector in the levels above the top of the nocturnal radiation inversion ...

Development of Low-Level Jets during TAMEX

Monthly Weather Review, 1995
Abstract Detailed synoptic-scale map analysis and diagnosis for all six low-level jet (LLJ) cases that occurred during the Taiwan Area Mesoscale Experiment (TAMEX) were made to study the structure and the development of the LLJs. It was shown that the development of these LLJs was closely linked to the development of a lee trough to the cast of the ...

The Koorin nocturnal low-level jet

Boundary-Layer Meteorology, 1985
It has been long known by Australian meteorologists that a nocturnal jet is a frequent feature of the low-level wind profile at Daly Waters in the Northern Territory of Australia. The Koorin Expedition during the southern winter of 1974 obtained data on wind and temperature profiles in the boundary layer which form an ideal base for the study of this ...

On the theory of the East African Low Level Jet Stream

pure and applied geophysics, 1977
Several theoretical models for the East African Low Level Jet Stream are described. They all share the notion that the northward advection of planetary vorticity across the equator, coupled with the presence of a north—south mountain barrier, leads to the formation of a low-level western boundary current (akin to the Gulf-Stream) along the equatorial ...

On the Formation of the Low-Level Jet over Texas

Monthly Weather Review, 1980
Abstract The low-level jet (LLJ) in the winter half-year originates as a south wind over the high plains of Colorado. Kansas, western Oklahoma and West Texas. After formation, the LLJ spreads horizontally and upstream toward the Gulf of Mexico. The air in the LLJ becomes humid when the entrance to the jet moves to the Gulf.

A nocturnal low level jet during PUKK

Boundary-Layer Meteorology, 1985
A nocturnal low-level jet characterized by a distinct inertial oscillation lasting from around sunset until sunrise the next day was observed during the coastal experiment PUKK. The phenomenon appeared over an area of at least 40 km in diameter; it thus had a mesoscale extension.

The Intra‐Americas Sea Low‐level Jet

Annals of the New York Academy of Sciences, 2008
A relevant climate feature of the Intra‐Americas Sea (IAS) is the low‐level jet (IALLJ) dominating the IAS circulation, both in summer and winter; and yet it is practically unknown with regard to its nature, structure, interactions with mid‐latitude and tropical phenomena, and its role in regional weather and climate.

The dynamic mechanism of the formation of the low level jet

Advances in Atmospheric Sciences, 1990
The ordinary multidimensional reductive perturbation method is generalized so as to apply to the general case including the dissipative factor. With this the corresponding Cubic-Schrodinger equation is deduced, and by the preliminary study of its solution, it shows that it is more admissible to consider atmospheric meso-scale systems as the nonlinear ...

Raptor responses to low-level jet aircraft and sonic booms

Environmental Pollution, 1991
We estimated effects of low-level military jet aircraft and mid- to high-altitude sonic booms (actual and simulated) on nesting peregrine falcons (Falco peregrinus) and seven other raptors by observing their responses to test stimuli, determining nesting success for the test year, and evaluating site reoccupancy rates for the year following the tests ...
