The northern polar jet stream is the most important one for aviation and weather forecasting, as it is much stronger and at a much lower altitude than the subtropical jet streams and also covers many countries in the northern hemisphere, [38] while the southern polar jet stream mostly circles Antarctica and sometimes the southern tip of South ...
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 ...

The current period of very cold weather in North America will fire-up the jet stream, as the frigid air meets warmth over the Atlantic. Indeed, the winds high aloft across the ocean may reach over ...
During El Niño, the jet stream is oriented from west to east across the southern portion of the United States, making the region more susceptible to severe weather outbreaks. During La Niña, the jet stream and severe weather are likely to be farther north than normal. [17]
Over very long time periods (hundreds of millions of years), a tectonic uplift can significantly alter their major elements, such as the jet stream, and plate tectonics may shift ocean currents. During the extremely hot climates of the Mesozoic, a third desert belt may have existed at the Equator.
The jet stream, essentially a river of air in the atmosphere that storms flow through, is locked in an almost perfect line from west to east and will continue to funnel fast-moving storms across ...
During the negative phase, the jet stream is retracted over East Asia, producing a blocking weather pattern over the North Pacific. [1] [7] Some of the energy that drives the PNA originates from the barotropic instability produced by the jet, potentially exciting Rossby waves. Shifts in the jet stream can induce changes in air pressure ...
