Quizplus · Accepted Answer

The jet stream is a high-speed, narrow current of upper-level winds that mainly flows from west to east in the upper-level westerly geostrophic wind flows. Rossby waves are a type of atmospheric wave that is associated with the jet stream but they are not the most prominent movement. Cyclones and anticyclones are weather systems that are associated with the jet stream but they are not the most prominent movement either.
