Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.
On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape.
Weather portal. Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape.
Influence on Surface Winds The primary way jet streams influence surface winds is by transporting High and Low pressure systems across the country. Due to the Laws of Conservation, changes in upper level (UL) flow of jet streams are balanced by ageostrophic winds which induce vertical circulation.

Where are jet streams generally located?
Jet streams are located about five to nine miles above Earth’s surface in the mid to upper troposphere — the layer of Earth’s atmosphere where we live and breathe. Airplanes also fly in the mid to upper troposphere.
What are jet streams and where are they located?
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).
They are found in the upper levels of Earth’s atmosphere at the tropopause – the boundary between the troposphere and stratosphere (see atmospheric layers). Jet streams are important because they contribute to worldwide weather patterns and as such, they help meteorologists forecast weather based on their position.
What is a jet stream simple definition?
Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.
What are jet streams answer?
Jet streams are bands of strong wind that generally blow from west to east all across the globe. They impact weather, air travel and many other things that take place in our atmosphere.
What is jet stream in geography?
Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. An air current is a flowing movement of air within a larger body of air.
What is a jet stream and what causes it?
What Causes Jet Streams? Jet streams exist because of a difference in temperature between two air masses. As the sun doesn’t heat the world evenly, there is more hot air near the Earth’s Equator and cold air near the North and South Poles. As the warm air expands, it becomes lighter and creates a warm air current.
What is the jet stream and how does it affect climate?
The jet stream flows high overhead and causes changes in the wind and pressure at that level. This affects things nearer the surface, such as areas of high and low pressure, and therefore helps shape the weather we see. Sometimes, like in a fast-moving river, the jet stream’s movement is very straight and smooth.
What are jet streams and how they affect the climate of India?
Answer. (i) Jet streams are cold fast blowing winds that develop in the upper layers of the atmosphere. (ii) They influence the climate of India as the westerly jet stream prevails over the North Indian Plains during the winter months, while the easterly jet stream steers the tropical depression over India.
What are jet streams in climate?
Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.
What is a jet stream class 9?
Ans. 1. Jet streams are fast flowing narrow meandering air currents found in the atmosphere of some planets including earth. The westerly flows are responsible for the western disturbances experienced in the north and north western parts of the country.
Do jet streams cause weather?
How Do Jet Streams Affect Weather? The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. However, if a weather system is far away from a jet stream, it might stay in one place, causing heat waves or floods.

Some regions of high vertical wind shear are marked by clear-air turbulence (CAT). Jet streams whose extents are relatively isolated are called jet streaks. Well-defined circulation patterns of rising and sinking air are usually found just upstream and downstream, respectively, from jet streaks (that are not too curved).
SVS: European Jet Stream – NASA
Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere’s polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere. The jet is created by the convergence of cold air masses descending from the Arctic and rising warm air from the tropics.
