The term "jet stream" is also applied to some other winds at varying levels in the atmosphere, some global (such as the higher-level polar-night jet), some local (such as the African easterly jet). Meteorologists use the location of some of the jet streams as an aid in weather forecasting .
The Tropical Easterly Jet is the meteorological term referring to an upper level easterly wind that starts in late June and continues until early September. This strong flow of air that develops in the upper atmosphere during the Asian monsoon is centred on 15°N, 50-80°E and extends from South-East Asia to Africa.
The coldest weather of the season to date will be due to a phenomenon called a polar vortex, an upper-level jet stream that typically circulates around both the North and South Poles, but can push ...
Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there.
This evening's weather balloon launch detected the 2nd strongest upper-level wind recorded in local history going back to the mid 20th century! Around 34,000-35,000 ft, winds peaked around 230 kt ...
Upper-level jet streams. Associated with upper-level jet streams is a phenomenon known as clear air turbulence (CAT), caused by vertical and horizontal wind shear connected to the wind gradient at the edge of the jet streams. [5] The CAT is strongest on the anticyclonic shear side of the jet, [6] usually next to or just below the axis of the ...
A dip in the jet stream is plunging southeastward in tandem with Blair, providing robust upper-level wind support. (MORE: 4 Weather Stories We Typically Watch In January)
Kona Low over Hawaii, an example of a cut-off low from the main core of the jet stream. [1]A cut-off low (or cutoff low), sometimes referred to as the weatherman's woe, is defined by the National Weather Service as "a closed upper-level low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current."
