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

A jet stream is defined as a current of rapidly moving air that is usually several thousand miles long and wide but is relatively thin. They are found in the upper levels of Earth's atmosphere at the tropopause - the boundary between the troposphere and stratosphere (see atmospheric layers) Planes capitalize on the jet stream for fast flights. Jet streams can be located in the atmospheres of some planets which include the earth, and they are narrow and fast flowing air currents. The path of a jet stream tends to adopt a meandering shape as the current can be observed swinging from side to side A JET STREAM IS A relatively narrow band of strong horizontal winds in the atmosphere. This band is 100 to 200 mi (250 to 500 km) wide and 1 to 2 mi (several km) deep. The winds in this band are stronger than those in horizontal or vertical regions adjacent to this band. The boundaries of the jet stream, therefore, contain significant wind shear 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 Jet stream, a region of long, narrow, high-speed winds that typically flow northeastward, eastward, and southeastward in the middle and upper troposphere or lower stratosphere. Jet streams are characterized by wind motions that generate strong vertical shearing action, which is thought to be largely responsible for clear air turbulence

Meaning of Jet Stream: The strong and rapidly moving circumpolar westerly air circulation in a narrow belt of a few hundred kilometers width in the upper limit of tropo­sphere is called jet stream. The circulation of westerly jet stream is confined between poles and 20° latitudes in both the hemispheres at the height of 7.5-14 km The polar jet stream forms at about 10 km (6.2 miles) of altitude, while the subtropical jet stream is produced at a higher altitude, close to 13 km (8.8 miles). What causes jet streams Warming at the equator produces a low pressure system, while at the poles excessive cooling produces a high pressure system Additionally, jet stream often house pockets of winds that move faster than the surrounding jet stream winds. These jet streaks play an important role in precipitation and storm formation: If a jet streak is visually divided into fourths, like a pie, its left-front and right-rear quadrants are the most favorable for precipitation and storm development Polar front jet stream, also called polar front jet or midlatitude jet stream, a belt of powerful upper-level winds that sits atop the polar front.The winds are strongest in the tropopause, which is the upper boundary of the troposphere, and move in a generally westerly direction in midlatitudes.The vertical wind shear which extends below the core of this jet stream is associated with. Jet Streams are the fast-flowing winds. They are narrow and meandering air currents in the atmosphere. They flow in narrow cores due to the strong pressure gradient. The speed of the wind is high at the center of the jet stream

A jet stream is a fast-flowing river of air at the boundary between the troposphere and the stratosphere. Jet streams form where there is a large temperature difference between two air masses. What is the jet stream and how does it work Jet streams These are very strong and fast-moving meandering wind bands.

GK: Understanding Jet Stream (GEOGRAPHY) 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 Stream is a geostrophic wind blowing horizontally through the upper layers of the troposphere, generally from west to east. Jet Streams develop where air masses of differing temperatures meet. So, usually surface temperatures determine where the Jet Stream will form Jet streams are winds that circle around the earth with poles as their centers Jet streams are air currents found in the tropopause which is the transition between troposphere and stratosphere. These are westerly flows which blow south of the Himalayas, all through the year except in summer. The western cyclonic disturbances experienced in the north and north-western parts of the country are brought in by this westerly flow jet stream A narrow current of strong wind circling the Earth from west to east at altitudes of 10 to 15 miles (16 to 24 kilometers) above sea level. There are usually four distinct jet streams, two each in the Northern and Southern Hemispheres. The American Heritage® Student Science Dictionary, Second Edition

Illustration of a typical jet stream. A jet stream is defined as a narrow zone of high-speed winds. They can extend several thousand miles long Jet streams are strong westerly winds generally concentrated in a relatively narrow and shallow above the earth's troposphere.

The first one is the polar jet which is considered as the strongest jet stream जेट धारा 11- 12 किलोमीटर की ऊंचाई पर टेढ़े-मेढ़े रास्ते से चलने वाली ऊपर ही.

Back when we studied mid-latitude cyclones, we talked a bit about the jet stream, which is a channel of fast winds near the top of the troposphere. But, the jet stream we talked about is really the mid-latitude jet stream, which regularly affects weather in the mid-latitudes. The mid-latitude jet stream isn't Earth's only jet stream, though Jet streams are high velocity westerly winds. The westerly flows are responsible for the western disturbances experienced in the north and north-western parts of the country. These are of two types, westerly jet streams move to the north of Himalayas in summer and easterly jet streams move to the peninsular India The jet stream core is surrounded by slower moving air that has an average velocity of 130 kilometers per hour in winter and 65 kilometers per hour in summer. Associated with the polar jet stream is the polar front Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth New questions in Geography what are the major economic activities of the people of the cold reason mention i
