The document discusses jet streams, which are narrow bands of strong wind that form in the upper atmosphere. Jet streams typically flow from west to east at speeds of up to 250 mph at altitudes between 8-16 km. They form along boundaries between hot and cold air masses, driven by pressure differences and the Coriolis effect from Earth's rotation. There are two main types of jet streams: the polar front jet at 50-60 degrees latitude and the subtropical jet at 30 degrees latitude. Jet streams play a key role in determining weather patterns and steering cyclonic storms.

3. • Jet Streams Are Narrow Bands Of Strong Wind In The
Upper Levels Of The Atmosphere.
• Jet Streams Follow The Boundaries
Between Hot And Cold Air
• HEIGHT : 8-16 Km
• SPEED : Can Reach Upto 250mph
• Jet Stream Blows From West To East.
JET STREAMS ARE LIKE RIVERS OF WIND HIGH ABOVE IN THE
ATMOSPHERE
