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.

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 ...

Some aspects of modelling low-level jets

Boundary-Layer Meteorology, 1988
An improved non-stationary two-layer model is presented for the simulation of wind speed maxima in the nocturnal boundary layer. The model is based on the idea of Blackadar (1957), who proposed as forcing mechanism an inertial oscillation of the ageostrophic component of the wind vector in the levels above the top of the nocturnal radiation inversion ...

The Koorin nocturnal low-level jet

Boundary-Layer Meteorology, 1985
It has been long known by Australian meteorologists that a nocturnal jet is a frequent feature of the low-level wind profile at Daly Waters in the Northern Territory of Australia. The Koorin Expedition during the southern winter of 1974 obtained data on wind and temperature profiles in the boundary layer which form an ideal base for the study of this ...

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 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.

CLIMATOLOGY OF THE LOW LEVEL JET

Monthly Weather Review, 1968
Abstract Geographical and diurnal variations in the frequency of occurrence of strong low level wind maxima are determined 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.

Nocturnal low-level jet over a shallow slope

Acta Geophysica, 2009
A simple theory is presented for a nocturnal low-level jet (LLJ) over a planar slope. The theory extends the classical inviscid inertial-oscillation model of LLJs to include up- and downslope motion in the boundary layer within a stably stratified environment.

The Intra‐Americas Sea Low‐level Jet

Annals of the New York Academy of Sciences, 2008
A relevant climate feature of the Intra‐Americas Sea (IAS) is the low‐level jet (IALLJ) dominating the IAS circulation, both in summer and winter; and yet it is practically unknown with regard to its nature, structure, interactions with mid‐latitude and tropical phenomena, and its role in regional weather and climate.

Nocturnal basin low-level jets: an integrated study

Acta Geophysica, 2008
Low-level jets (LLJs) are a very common feature in the nocturnal stably stratified boundary layer. Many factors can intervene in their generation, linked basically to effects of baroclinity. A special kind of low-level jets is composed by the nocturnal katabatic and basin flows, generated over terrain slopes. A study of observed LLJs in the Duero Basin
