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.
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.
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 jet stream is a narrow, fast-flowing air current located high in the atmosphere that can influence weather patterns and affect the speed and efficiency of flight travel.
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 two narrow belts of fast-moving winds are called the jet streams. They are located at high altitudes in the atmosphere, with the polar jet stream and the subtropical jet stream being the most prominent ones.
