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 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.

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.

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

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 ...

Atmosphere, 2021 Wind shear at low altitudes represents a potential hazard to landing aircraft. Based on two wind lidar data sets of one year, the occurrence of low-level jets (LLJs), the vertical wind shear and the rotation of the wind direction were analysed. The lidar

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.
