- . Jet Stream current of rapidly moving air. The jet stream is a current of fast moving air found in the upper levels of the atmosphere. This rapid current is typically thousands of kilometers long, a few hundred kilometers wide, and only a few kilometers thick. Jet streams are usually found somewhere between 10-15 km (6-9 miles) above the earth's surface. The position of this upper-level jet stream denotes the location of the strongest SURFACE temperature contrast (as in the diagram below).

Pauls Quiz 158 Benjamin Franklin's Chart of The Gulf Stream . The Gulf Stream, together with its northern extension towards Europe, the North Atlantic Drift, is a powerful, warm, and swift Atlantic ocean current that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.

- The Gulf Stream, located along the eastern coast of the United States, is a fast, intense current known as a western-boundary current.These currents are located on the western side of every ocean basin. The Gulf Stream is a result of the wind pattern acting on most of the North Atlantic Ocean.The combination of the Trade Winds (10°- 25°N) blowing to the west and the Westerlies (35°- 55°N) blowing to the east cause the North Atlantic to rotate clockwise.long the east coast of Florida the current is fed by the Antilles Current, and the flow, now called the Gulf Stream, runs parallel to the coast until reaching Cape Hatteras where it leaves the coast and enters deeper water. While flowing in deep water the Stream often forms large meanders or flucuations in its path.

What is a Jet Stream? Each hemisphere has two primary jet streams — a polar and a subtropical. The polar jet streams form between the latitudes of 50 and 60 degrees north and south of the equator, and the subtropical jet stream is closer to the equator and takes shape at latitudes of 20 to 30 degrees.

How does the Gulf Stream effect climate? (Answer #1). The gulfstream is a surface current in the Atlantic ocean that flows northward along the east coast of the U.S. Surface currents are set in motion by the winds. This movement of water in turn effects the circulation in the atmosphere.

Jet Streams The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet. They are responsible for transporting the weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air. The polar jet sits at roughly 60°N latitude because this is generally where the polar front sits. The subtropical jet is at roughly 30°N latitude.

What is a Jet Stream? Jet streams are like rivers of wind high above in the atmosphere. These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns.

How the jet stream affects an airplane ride Jet streams are found in the upper atmosphere, usually above 32,000 feet. Meteorologists (scientists who study weather and climate in the atmosphere) know that jet streams can travel at hundreds of miles an hour.

Gulf Stream Source: NASA. The Gulf Stream, together with its northern extension towards Europe, the North Atlantic Drift, is a powerful, warm, and swift Atlantic ocean current that originates at the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.he North Atlantic Current of the Gulf Stream, along with similar warm air currents, helps keep Ireland and the western coast of Great Britain a couple of degrees warmer than the east. However, the difference is most dramatic in the western coastal islands of Scotland.

The Jet Stream 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).

- Among the more fascinating features of upper-air circulations are discontinuous bands of relatively strong winds (usually in excess of 30 metres per second) called jet streams. As with other wind fields that increase with increasing height, jet streams can be explained as an application of the thermal-wind equation.

Glossary of Geography Terms and Definitions The jet stream blows through the troposphere, the layer of the Earth's atmosphere that comes into contact with the ground. In some instances, the jet stream can cause very cold weather patterns in places that are typically mild. Mount Everest is so tall that it sits in the jet stream.

Jet Streams Jet streams usually sit at the boundary between the troposphere and the stratosphere at a level called the tropopause. This means most jet streams are about 6-9 miles off the ground. Figure A is a cross section of a jet stream.

- The Hadley cell, named after George Hadley, is a tropical atmospheric circulation which features rising motion near the equator, poleward flow 10–15 kilometers above the surface, descending motion in the subtropics, and equatorward flow near the surface.echanism [edit]. The major driving force of atmospheric circulation is solar heating, which on average is largest near the equator and smallest at the poles.

Atmospheric Forces Air parcels will try to move from areas of high pressure to areas of low pressure. In addition, colder temperatures near the poles generally are associated with higher pressures than warmer temperatures near the equator. Thus, unequal solar heating of the earth directly causes large-scale winds, called the jet stream.

What is a Jet Stream? Jet streams are typically active at 20,000 feet (6,100 meters) to 50,000 feet (9,144 meters), or about 7 miles (11 kilometers) above the surface and travel in what is known as the troposphere of Earth’s multi-layered atmosphere.

Module 9 / Westerlies and the Jet Stream 1 The polar-front jet stream exists along the region where cold polar air and warm air masses are in contact. 2  Hence, weather is relatively cold when the polar-front jet stream is south of a particular location and relatively warm when the jet stream is north of the location.

The Jet Stream: What It Is and How It Affects Our Weather Jet Stream Location, Speed, Direction. Jet streams live at the tropopause (about 6 to 9 miles off of the ground) and are several thousand miles long. Jet stream winds range in speed from 120 to 250 mph, but can reach more than 275 mph. Oftentimes, the jet houses pockets of winds that move faster than the surrounding jet stream winds. These jet streaks play an important role in precipitation and storm formation.

Introduction to the Atmosphere Most of the water vapor in the atmosphere comes from the oceans. 1  Most of the precipitation falling over land finds its way back to oceans. 2  About two-thirds returns to the atmosphere via the water cycle.

The Jet Stream While jet streams do exist in the southern hemisphere, they are strongest between latitudes of 30°N and 60°N. The weaker subtropical jet stream is located closer to 30°N.

A Rough Guide to the Jet Stream: what it is, how it works and how it is responding to enhanced Arctic warming Barely a week goes by these days in the Northern Hemisphere without the jet stream being mentioned in the news, but rarely do such news items explain in detail what it is and why it is important.

What Is a Jet Stream? The winds in a jet stream are caused by differences in temperature between two large air masses that border the tropopause. These temperature differences create differences in air pressure between the air masses. As colder air tries to move toward the warmer air, winds form.

(s). The Mid-Latitude Cyclone The mid-latitude cyclone east of Greenland is at the end of its life cycle. In their mature stage, mid-latitude cyclones have a warm front on the east side of the storm's center and a cold front to the west. The cold front travels faster than the warm front. Near the end of the storm's life the cold front catches up to the warm front causing a condition known as occlusion.

Jet stream Jet streams can split into two when it encounters an upper-level low, that diverts a portion of the jet stream under its base, while the remainder of the jet moves by to its north. The wind speeds are greatest where temperature differences between air masses are greatest, and often exceed 92 km/h (50 kn; 57 mph).

- The jet stream is a fast flowing, river of air found in the atmosphere at around 12 km above the surface of the Earth just under the tropopause. They form at the boundaries of adjacent air masses with significant differences in temperature, such as of the polar region and the warmer air to the south.
