An easterly tip jet off Cape Farewell, Greenland. I: Aircraft observations [PDF]

, 2009
An easterly tip jet event off Cape Farewell, Greenland, is described and analysed in considerable detail. In Part I of this study (this paper) comprehensive aircraft-based observations are described, while in Part II of this study numerical simulations ...

Near-infrared jet emission in the microquasar XTE J1550-564 [PDF]

, 2011
Context: Microquasars are accreting Galactic sources that are also observed to launch relativistic jets. A key signature of the ejection is non-thermal radio emission. The level of this jet component at high frequencies is still poorly constrained. Aims:

Measurements and Modelling of Offshore Wind Profiles in a Semi-Enclosed Sea

Atmosphere, 2019
A conically scanning, continuous-wave LIDAR is placed on an island in the central Baltic Sea with large open-water fetch, providing wind and turbulence profiles up to 300 m height.

A low-level jet in eastern Iran: a possible factor in dust events in the region [PDF]

Desert, 2015
One of the world's major mineral dust source regions lies along the border between Iran and Afghanistan. In this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region.

Low‐Level Baroclinic Jets Over the New Arctic Ocean [PDF]

Journal of Geophysical Research: Oceans, 2018
AbstractDuring the Sea State cruise in the fall of 2015, in the Chukchi/Beaufort Sea region, there were five strong (>10 m s−1) surface wind events associated with low‐level atmospheric jets. These jets were analyzed using rawinsonde observations, ship measurements, and a numerical forecast model.

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

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.

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.

Learning to identify semi-visible jets

Journal of High Energy Physics, 2022
We train a network to identify jets with fractional dark decay (semi-visible jets) using the pattern of their low-level jet constituents, and explore the nature of the information used by the network by mapping it to a space of jet substructure ...

Analytical description of a nocturnal low‐level jet [PDF]

Quarterly Journal of the Royal Meteorological Society, 2010
AbstractAn exact analytical solution of the equations of motion is presented for the Blackadar conceptual model of the nocturnal low‐level jet as an inertial oscillation arising from the sudden release of frictional constraint (near‐cessation of dry‐convective turbulent mixing) near sunset.
