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 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 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 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.


Fast moving currents of air found near the top of the troposphere are called?

Jet streams. They are high altitude bands of fast-moving air that flow from west to east in the upper troposphere and lower stratosphere. Jet streams are driven by a combination of temperature gradients, the Earth's rotation, and atmospheric pressure differences.


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 does jet streams effect the us weather pattern?

It controls where the clouds go. It also causes high and low pressure systems


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.
