Experimental and computational studies of factors affecting impinging jet flowfields [PDF]
, 2009 An experimental and computational study was made of a single circular jet impinging onto a flat ground board. A 1/2" nozzle running at a fixed nozzle pressure ratio of 1.05 was used in the experimental phase (giving an nozzle exit Reynolds number of ...

Low Level Jet Wind Shear in the Sahel [PDF]
International Journal of Engineering Research in Africa, 2013 In the Sahel, a vertical wind shear appears in the dry and in the wet seasons. In Niamey, Niger, during the dry season, the period of strong shears is clearly linked to the Nocturnal Low Level Jet (LLJ) since it occurs in a narrow time period around 06H00 UTC at 60% of the cases reach shears which require an alert to the pilots (higher than 4 ms-1 per ...

Low‐Level Jets and the Convergence of Mars Data Assimilation Algorithms [PDF]
Journal of Geophysical Research: Planets, 2022 AbstractData assimilation is an increasingly popular technique in Mars atmospheric science, but its effect on the mean states of the underlying atmosphere models has not been thoroughly examined. The robustness of results to the choice of model and assimilation algorithm also warrants further study.

Mesoscale Ascent in Nocturnal Low-Level Jets [PDF]
Journal of the Atmospheric Sciences, 2018 A theory for gentle but persistent mesoscale ascent in the lower troposphere is developed in which the vertical motion arises as an inertia–gravity wave response to the sudden decrease of turbulent mixing in a horizontally heterogeneous convective boundary layer (CBL).

A Parametric Study of Vane and Air-jet Vortex Generators [PDF]
, 1998 An experimental parametric sturdy of vane and air-jet vortex generators in a turbulent boundary layer has been carried out. Experiments were carried out in two facilities, one with a free-stream velocity of 20 m/s and a boundary layer thickness (6) of ...

Behaviour of water in jet fuel: a literature review [PDF]
, 2013 This review gives a detailed account of the different types of water contaminated fuel and the conditions that bring about each form of contamination. It also considers studies that have been done to date that investigate the physics behind the behaviour

Offshore Migration of Summer Monsoon Low‐Level Jet on a Diurnal Scale
Geophysical Research Letters, 2023 This study investigates the diurnal migration of the low‐level jet (LLJ) over the Bay of Bengal in the summer monsoon, which remains understudied despite the well‐documented diurnal offshore propagation of rainfall worldwide.

Numerical simulation of future low-level jet characteristics
Meteorologische Zeitschrift, 2012 In this paper, results of numerical simulations of low-level jet (LLJ) characteristics are presented. By forcing a boundary layer model with the results of a regional climate model, long time series have been calculated which are analyzed with special ...

Low-level stratiform clouds and dynamical features observed within the southern West African monsoon [PDF]
Atmospheric Chemistry and Physics, 2019 During the boreal summer, the monsoon season that takes place in West Africa is accompanied by low stratus clouds over land that stretch from the Guinean coast several hundred kilometers inland. Numerical climate and weather models need finer description
