On Earth, 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, while the southern polar jet stream mostly circles Antarctica and sometimes the southern tip of ...
Zonal wind forecast for the Arctic - The bold red line is the average polar vortex strength over time. ... Features such as high low pressure systems as well as the jet stream act as conveyor ...
Clear-air turbulence. In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues such as clouds, and is caused when bodies of air moving at widely different speeds meet. The atmospheric region most susceptible to CAT is the high troposphere at altitudes of around 7,000–12,000 m ...
"A more notable storm with a dip in the jet stream will barrel into Washington, Oregon and northern California from late week into the upcoming ... Las Vegas is forecast to have its first sub-100 ...
Polar vortex. A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low- obliquity planetary bodies. [1] The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and ...

On a day-to-day basis airliners are routed to take advantage of the jet stream tailwind to improve fuel efficiency. [100] Aircrews are briefed prior to takeoff on the conditions to expect en route and at their destination. [101] Additionally, airports often change which runway is being used to take advantage of a headwind.
Any disturbance in the jet stream or weak area of low pressure can lead to an uptick in thunderstorms. A small percentage of the thunderstorms may become severe with damaging wind gusts.
