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 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 polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.
A. The subtropical jet stream lies between the westerlies and polar easterlies; this statement is true. B. The polar jet stream typically flows to the east, while the subtropical jet stream flows towards the west.
The jet stream is typically faster in the winter due to greater temperature contrasts between polar and tropical regions. This temperature difference creates stronger winds that drive the jet stream at higher speeds during the winter months.
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 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 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.
The jet stream
The polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.

No. The jet stream is in the upper troposphere and lower stratosphere.
