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.

How many jet streams are there on earth?
There are typically four jet streams on Earth: two in each hemisphere. These are the polar jet streams and the subtropical jet streams. Polar jet streams are found closer to the poles, while subtropical jet streams are located closer to the equator.
Relation between ITCZ and easterly jet streams?
The Intertropical Convergence Zone (ITCZ) is a region near the equator where trade winds converge, creating a low-pressure area. Easterly jet streams are high-altitude wind currents that flow eastward in the tropics. The ITCZ can influence the formation and position of easterly jet streams by influencing the pressure and temperature gradients in the region, which in turn affect the direction and speed of the jet streams.
How many jet streams are there total on earth?
There are typically six jet streams on Earth: three in each hemisphere. The strongest and most well-known ones are the polar jet streams and the subtropical jet streams. These high-altitude, fast-flowing air currents have a significant impact on weather patterns.
How many jet streams are there in the world?
There are typically four main jet streams in Earth's atmosphere: two polar jet streams, located near the poles, and two subtropical jet streams, located closer to the equator. These jet streams are high-altitude, fast-flowing air currents that play a significant role in shaping weather patterns.
What do meteorologists use to study jet streams?
Meteorologists use weather balloons, aircraft data, satellites, and computer models to study jet streams. These tools help them monitor the speed, direction, and strength of jet streams in the atmosphere.
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.
How does the jet streams move across North America?
The winds of a jet stream blow storms.
What is it called when wind blow south in a northern hemisphere?
Prevailing westerlies
How does the jets streams help move storms across the north America?
The winds of a jet stream blow storms.
How many jet streams are there on earth?
There are typically four jet streams on Earth: two in each hemisphere. These are the polar jet streams and the subtropical jet streams. Polar jet streams are found closer to the poles, while subtropical jet streams are located closer to the equator.
Why do jet streams change their path in winter?
Jet streams change their path in winter due to the tilt of the Earth's axis. This tilt causes temperature differences between the poles and the equator, which in turn affects the strength and position of the jet stream.
What are narrow belts of high speed winds?
Jet Streams
Do jet streams blow at speeds of 200 to 400 kilometers per hour?
Yes, jet streams are high-altitude, fast-flowing air currents that can reach speeds of 200 to 400 kilometers per hour or even higher. These strong winds occur in the upper levels of the atmosphere and play a significant role in shaping weather patterns around the world.
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
