Learning to identify semi-visible jets
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 ...

Based on conventional observation data and NCEP/NCAR 6-hour reanalysis data with 1°×1° resolution, we analyzed the characteristics and causes of a heavy snowstorm event in southern Henan in the beginning of January 2018. The results show that this event,

Wind pressure on a single building immersed in a low-jet wind profile [PDF]
This paper for the first time discuss the wind pressure distribution on the building surface immersed in wind profile of low-level jet rather than a logarithmic boundary-layer profile.

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

CLIMATOLOGY OF THE LOW LEVEL JET
(Uploaded by Plazi for the Bat Literature Project) Geographical and diurnal variations in the frequency of occurrence of strong low level wind maxima arc detcrmined using 2 yr. of wind data from 47 rawinsonde stations in the United States. Maximum frequency of occurrence is found in the Great Plains at approximately 37'N. and 98"W. The vast majority of

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

Low Level Jets over the Southern North Sea
An extensive analysis of Low Level Jets (LLJs) over the Southern North Sea is presented. The study is based on observational data from a wind LiDAR and a passive microwave radiometer, operated from May 2015 to October 2016 on the FINO1 platform, as well as on mesoscale simulations by WRF-ARW. Besides evaluations on LLJ occurrence, intensity, direction,

Role of west Asian surface pressure in summer monsoon onset over central India
Using rain-gauge measurements and reanalysis data sets for 1948–2015, we propose a mechanism that controls the interannual variation of summer monsoon onset over central India.
