The jet stream is a band of reliably strong wind that plays a key role in keeping colder air north and warmer air south. But when the vortex weakens, part of the weakened low-pressure system can …

Jet streams are bands of strong wind that generally blow from west to east all across the globe.…

For example, high in the atmosphere, the jet streams typically blow across Earth from west to east. The trade winds are air currents closer to Earth’s surface that blow from east to west near the equator.

Much like a river is water moving over land, an atmospheric river is a stream of water vapor moving in the sky.

The polar jet stream blows cold air southward out of Canada and eastward toward the ocean. The Atlantic Ocean is warm, thanks to the Gulf Stream–a warm ocean current.
