Jet streams are fast moving belts of wind high in the atmosphere- there are two of them in the hemisphere, with the Polar Jet being the stronger of the two. The reasons for its existence are twofold: one being the rotation of the Earth causes angular momentum to be transported to higher latitudes whereupon it is basically "released" and returned to the Earth via the jet stream. The subtropical jet stream owes its existence to this as well as the mechanism of this momentum transport from the Tropics - via large-scale eddies in the atmosphere (largely, the Hadley Cell). The eddy flux of zonal (west-east) momentum peaks at about the tropopause level at 35 degrees latitude, where it is poleward in both hemispheres and strongest in winter.

What are high altitude rivers of air?
you mean jet streams...or thermals?
Relation between ITCZ and easterly jet streams?
The ITCZ is a convergence zone for the currents and it is situated along the equator. The easterly jet streams and the other winds that blow from the tropical end up converging at the ITCZ.
Jet streams generally flow toward the?
The major jet streams on Earth are westerly winds that flow west to east.
Why does a jet stream curve and bend?
Think about it this way. If it was flat then jet streams would be straight. But the Earth is round so jet streams are curved because of the curvature of the Earth.
How fast are jet streams?
200 mails
How do jet streams create local storms?
Jet Streams are fast blowing winds above the troposphere. The blow at speeds of upto 120kmph. When two jet streams collide it causes storms.
Do jet streams blow at speeds of 200 to 400 kilometers per hour?
Jet streams blow at speeds of 200 to 400 kilometers per hour.
How does the jet streams move across North America?
The winds of a jet stream blow storms.
What are high altitude rivers of air?

What is it called when wind blow south in a northern hemisphere?
Prevailing westerlies
What are narrow belts of high speed winds?
Jet Streams
Relation between ITCZ and easterly jet streams?
The ITCZ is a convergence zone for the currents and it is situated along the equator. The easterly jet streams and the other winds that blow from the tropical end up converging at the ITCZ.
How does the jets streams help move storms across the north America?
The winds of a jet stream blow storms.
Fast moving currents of air found near the top of the troposphere are called?
Jet streams~ Rebecca
Where are the major jet streams in the ocean?
There are 2 jet streams in the northern hemisphere and 2 in the southern hemisphere. They are known as the subtropical jet stream and the polar jet streams subsequently for get side.
What are high altitude high velocity of air called?
jet streams
How do jet streams differ from wind in the lower atmosphere?
JET Streams.The winds of the upper troposphere are quite different from the winds in the lower troposphere.They are stronger and blow in a different direction, mostly out of the west
