Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere, typically occurring around 30,000 feet (9,100 meters) in elevation.
Within jet streams, the winds blow from west to east, but the band often shifts north and south because jet streams follow the boundaries between hot and cold air.
Since these hot and cold air boundaries are most pronounced in winter, jet streams are the strongest during both the northern and southern hemisphere winters.

Explain how temperature differences between air masses contribute to the formation of jet streams.
In which layer of the atmosphere do subtropical jet streams occur?
Describe the general direction of jet stream winds and explain why they blow that way.
Examine the diagram showing two jet streams in each hemisphere. Compare the polar jet and subtropical jet in terms of latitude and wind strength, and explain what causes these differences.
Explain why jet streams are stronger during winter in both hemispheres.
Which of the following best explains why jet streams shift north and south throughout the year?
At what latitude and atmospheric layer would a subtropical jet stream most likely be found?
Explain one way jet streams influence local weather patterns in mid-latitude regions.
