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.

Fast moving currents of air found near the top of the troposphere are called?
Jet streams~ Rebecca
What are narrow belts of high speed winds?
Jet Streams
What cause of rotation of earth?
jet streams
Where are the jet streams located?
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).
Narrow belts of strong winds?
jet streams
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.
What are high altitude rivers of air?
you mean jet streams...or thermals?

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
What two major jet streams are in the northern hemisphere?
The Polar Jet Stream and the Subtropical Jet Stream are the two strongest jet streams in the Northern Hemisphere. The Southern Hemisphere has two major jet streams like the Northern Hemisphere.
Jet streams generally flow toward the?
The major jet streams on Earth are westerly winds that flow west to east.
How does jet streams effect the us weather pattern?
It controls where the clouds go. It also causes high and low pressure systems
What are polar jet streams?
My balls
What are narrow belts of high speed winds?
Jet Streams
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.
What are the two jet streams in the northern hemisphere?
mid latitude jet stream and jet stream
