All of the above responses are correct. Polar jet streams form due to a combination of air masses moving away from each other, rapid changes in wind direction, the presence of high-pressure systems, and the interaction between warm and cold air masses. These factors contribute to the formation and maintenance of the strong and narrow bands of high-altitude winds known as jet streams.
