A nocturnal low level jet during PUKK

Boundary-Layer Meteorology, 1985
A nocturnal low-level jet characterized by a distinct inertial oscillation lasting from around sunset until sunrise the next day was observed during the coastal experiment PUKK. The phenomenon appeared over an area of at least 40 km in diameter; it thus had a mesoscale extension.

The Low-Level Jet as a Western Boundary Current

Monthly Weather Review, 1976
Abstract The low-level jet which flows across the equator and up the Somali coast is considered as a western boundary current of the East African mountain chain. The jet is assumed to be forced by the low-level divergence in the subtropical high pressure belt of the Southern Hemisphere and convergence in the monsoon trough.

Raptor responses to low-level jet aircraft and sonic booms

Environmental Pollution, 1991
We estimated effects of low-level military jet aircraft and mid- to high-altitude sonic booms (actual and simulated) on nesting peregrine falcons (Falco peregrinus) and seven other raptors by observing their responses to test stimuli, determining nesting success for the test year, and evaluating site reoccupancy rates for the year following the tests ...

Observations of Low-level Jet Physics and Impacts

2020
The Great Plains low-level jet (LLJ) is a planetary boundary layer phenomenon of strong winds spanning thousands of square kilometers. These LLJs are primarily nocturnal, and an event?s lifetime can exceed 12 hours. LLJ wind speeds can reach 30 m/s within the lowest several hundred meters of the atmosphere. The formation mechanisms of the strongest and

Numerical Simulations of a Transverse Indirect Circulation and Low-Level Jet in the Exit Region of an Upper-Level Jet

Journal of the Atmospheric Sciences, 1985
A numerical study was performed of a severe weather event (tornado) which occurred on May 10, 1973 in the Ohio region. The situation was modeled with a primitive equation mesoscale dynamic formulation. Account was taken of precipitation, the planetary boundary layer parameters as bulk quantities, the vertical pressure gradient, and lateral boundary ...

Importance of Low-Level Jets to Climate: A Review

Journal of Climate, 1996
Abstract Low-level jets (LLJs) occur frequently in many parts of the world. These low-level wind speed maxima are important for both the horizontal and vertical fluxes of temperature and moisture and have been found to be associated with the development and evolution of deep convection.
