The impact of London on a low-level jet

2021
<p>The low-level jet (LLJ) is an important phenomenon that can affect (and is affected by) the turbulence in the nocturnal urban boundary layer (UBL). We investigate the interaction of a regional LLJ with the UBL during a 2-day period over London.

The Use of Low-Level Jets by Migrating Birds

Naturwissenschaften, 1999
Birds flying at high altitudes have occasionally been observed above mountain areas and the open sea. For the first time the regular occurrence of migrating birds flying within a low-level jet at heights of 5000 to almost 9000 m asl. have now been verified by radar above the Negev desert in southern Israel.

A LOW-LEVEL JET IN THE TROPICS

Monthly Weather Review, 1971
Abstract A temporary mesoscale network of pilot balloon stations on a tropical island (Barbados, West Indies) revealed the existence of a low-level jet at 700 m above mean sea level, with a maximum wind near 40 m/s and a duration of at least 2 hr. The phenomenon appears to be associated with the Venturi effect produced in the low levels by a traveling ...

Kinematics of the Low-Level Jet

Journal of Applied Meteorology, 1968
Abstract Winds and vertical velocities are examined in ten southerly low-level jets and then averaged in coordinate systems centered on the jet. The jet at 0600 CST is strongly supergeostrophic but is reflected in both geostrophic and ageostrophic components of the wind. Air is typically rising downstream from the wind maximum and sinking just upstream

Features of the Caribbean low level jet

International Journal of Climatology, 2007
AbstractThe Caribbean Low Level Jet (CLLJ) is shown to be a real and dominant climatological feature of the early summer Caribbean climate. It manifests as an intensification in the trade winds in the western Caribbean basin (70°W–80°W) with an east‐west axis along 15°N.
