Jet streams are the product of two factors: the atmospheric heating by solar radiation that produces the large-scale polar, Ferrel, and Hadley circulation cells, and the action of the Coriolis force acting on those moving masses. The Coriolis force is caused by the planet's rotation on its axis.
Meanders of the Northern Hemisphere's jet stream developing around the northern polar vortex (a, b) and finally detaching a "drop" of cold air (c). Orange: warmer masses of air; pink: jet stream; blue: colder masses of air. Rossby waves, also known as planetary waves, are a type of inertial wave naturally occurring in rotating fluids. [1]
A trough is the result of the movements of the air in the atmosphere. In regions where there is upward movement near the ground and divergence at altitude, there is a loss of mass. The pressure becomes lower at this point. At upper levels of the atmosphere, this occurs when there is a meeting of a mass of cold air and another hot one along a ...
The Atlantic jet stream is a fast and narrow current of air flowing from west to east and encircling the globe and is widely used by airplanes traveling east from North America to cut down on ...

British Aerospace Jetstream 41. C-GEOC at Sudbury, Ontario, Canada. The British Aerospace Jetstream is a small twin turboprop airliner, with a pressurised fuselage, developed as the Jetstream 31 from the earlier Handley Page Jetstream. A larger version of the Jetstream was also manufactured, the British Aerospace Jetstream 41.
SIGWX is a Significant Weather Chart defined by ICAO. Weather charts [1] being issued by World Area Forecast Centres [2] (from meteorological offices in London and Washington), presenting the most important meteorological phenomena relevant especially for air traffic transport. WAFC publishes them in two formats. BUFR code.
Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located. Use of constant pressure charts at the 700 and 500 hPa level can indicate tropical cyclone motion.
