Model sensitivity across scales: a case study of simulating an offshore low-level jet [PDF]

Wind Energy Science
In this study, a seven-member ensemble of mesoscale-to-microscale simulations with varying sea surface temperature (SST) is conducted for a case in which an offshore low-level jet was observed via floating lidar.

The South American Low-Level Jet Experiment

Bulletin of the American Meteorological Society, 2006
Abstract Moisture is transported in South America westward from the tropical Atlantic Ocean to the Amazon basin, and then southward toward the extratropics. A regional intensification of this circulation to the east of the Andes Mountains is called the South American low-level jet (SALLJ), with the strongest winds found over eastern Bolivia.

A Climatological Analysis of the Benguela Coastal Low‐Level Jet [PDF]

Journal of Geophysical Research: Atmospheres, 2019
AbstractThe Benguela coastal low‐level jet (CLLJ) is characterized by intense winds that occur around 400 m above sea level, within or at the top of the marine atmospheric boundary layer. The semipermanent St. Helen high‐pressure system, over the South Atlantic Ocean, and the inland thermal low‐pressure system, over the Namib Desert, are the synoptic ...

EFD-C(13)03/46 Comparisons Between EDGE2D/EIRENE Simulations and D and Low Z Impurity Spectral Emission from JET ITER-like Wall L-mode Plasmas [PDF]

, 2013
An understanding of the behaviour of the plasma edge and divertor physics is essential for the design of next-step machines such as ITER, for which JET with its ITER-Like Wall (ILW) of Be in the main chamber and W in the divertor is ideally suited.

Low-level jet characteristics over the Arctic Ocean in spring and summer [PDF]

Atmospheric Chemistry and Physics, 2013
Low-level jets (LLJ) are important for turbulence in the stably stratified atmospheric boundary layer, but their occurrence, properties, and generation mechanisms in the Arctic are not well known.

Winter and Summer Structure of the Caribbean Low-Level Jet [PDF]

Journal of Climate, 2008
Abstract The Caribbean region shows maxima in easterly winds greater than 12 m s−1 at 925 hPa in July and February, herein referred to as the summer and winter Caribbean low-level jet (LLJ), respectively. It is important to understand the controls and influences of the Caribbean LLJ because other LLJs have been observed to be related to ...

Jet energy measurement with the ATLAS detector in proton-proton collisions at s√=7 TeV [PDF]

, 2013
The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of s√=7 TeV corresponding to an integrated luminosity of 38 pb−1.

Mixed layer depths via Doppler lidar during low-level jet events

EPJ Web of Conferences, 2018
A low-level jet (LLJ) is a prominent wind speed peak in the lower troposphere. Nocturnal LLJs have been shown to transport and mix atmospheric constituents from the residual layer down to the surface, breaching quiescent nocturnal conditions due to high ...

The South America Low-Level Jet: form, variability and large-scale forcings

npj Climate and Atmospheric Science, 2023
Northerly low-level jets (LLJ) along the eastern Andes are important conduits of moisture transport and play central roles in modulating precipitation in South America.
