The jet stream is strongest in the upper troposphere, which is the region of the atmosphere located between about 7 to 12 kilometers above the Earth's surface.
The weatherman said that the latest jet stream would bring more cold air to the region on Friday. The jet flew over Wichita, leaving a trail of jet stream behind it.
It really doesn't change in speed. The jet stream is considered to be when the wind reaches 50 mph. In the United States, the jet streams tends to dip down from Canada and provide us with stronger westward winds. That is why you will see airplanes schedules tend to have two different times tables in the winter when flying west or east.
The polar jet stream is, on average, 10 kilometers (6 miles) in the atmosphere, which places it near the top of the Troposphere. The subtropical jet stream tends to be a little higher - around 13 kilometers - because the air is warmer. Warmer air takes up more space, therefore the top of the atmosphere is higher.Typically the jet stream is found between 200 and 300 hectopascals (hPa, which is equivalent to millibars, or mb). In atmospheric science, the altitude in the atmosphere is often given in terms of what the atmospheric pressure is for reasons that we won't get into. In any event, these are the levels we look at for the jet stream.The layer of the atmosphere where the jet stream resides is not completely clear. The most common definition given for the top of the troposphere is where the temperature stops decreasing and begins increasing. This is almost always at altitudes above 200mb. Therefore, the jet stream is generally found in the troposphere, near the tropopause. It is rarely as high as the stratosphere.
The jet stream is a high-altitude, fast-moving air current that flows from west to east in a wavy pattern in the atmosphere. There are polar and subtropical jet streams located in the upper levels of the troposphere, typically between 6 to 9 miles above the Earth's surface.
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.

The jet stream.
A jet stream is a region of strong winds high in the atmosphere where planes fly. If she flies a plane into this region, the plane will be accelerated. This will allow her to either fly faster, or fly at the same speed using less fuel.
The weatherman said that the latest jet stream would bring more cold air to the region on Friday. The jet flew over Wichita, leaving a trail of jet stream behind it.
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.
It really doesn't change in speed. The jet stream is considered to be when the wind reaches 50 mph. In the United States, the jet streams tends to dip down from Canada and provide us with stronger westward winds.

The jet stream is located in the tropopause, which is the boundary between the troposphere and the stratosphere. It typically flows at high altitudes, around 10-15 kilometers above the Earth's surface.
The ozone layer is located in stratosphere. It is a part of out atmosphere.
"Jet stream" is a weather term that starts with the letter J. It refers to narrow bands of strong wind in the atmosphere that can influence weather patterns.
