Briefly explains the jet stream, and how they are important to airplanes.

  • The main jet streams flow from the west in the upper atmosphere Jet streams are fast flowing, relatively narrow air found in the at around 11 kilometres above the surface of the, just under the

  • The major jet streams are westerly winds (flowing west to east) in both the and the ; this is due to the caused by Earth's rotation

  • Contents [] Description There are two main jet streams at polar, one in each hemisphere, and two minor streams closer to the

  • In the the streams are most commonly found between latitudes 30°N and 70°N for the polar jet stream, and between latitude 20°N and 50°N for the subtropical stream

  • Technically the wind speed has to be higher than 90km/h or 55 mph to be called a jet stream

  • Associated with jet streams is a phenomenon known as (CAT), which is the result of massive disturbances of air, caused by vertical and horizontal connected to the jet streams

  • [] Cause Jet streams can be explained as follows

  • [] Discovery The jet streams were first noticed by atmospheric scientists in the using and, later, but before widespread aviation the so-called ' winds' (or 'strong westerlies') were of little interest, and many observers thought that individual observations were simply freak occurrences

    Tells what the jet stream is, and how it affects storm paths.

  • Source: USA TODAY research by Chad Palmer, Graphic by John Herne Jet stream roars along high above earth By Jack Williams, The term "jet stream" is often used to refer to the rivers of wind high in the atmosphere - above about 20, 000 feet - that steer storms

  • ( Related graphic: ) Strictly speaking, as noted in the American Meteorological Society's Glossary of Weather and Climate , a jet stream is "a relatively narrow river of very strong horizontal winds (usually 50 knots or greater) embedded in the planetary winds aloft." The "planetary winds aloft" are the part of the Earth's general circulation of air that's not at the surface

  • Jet streams form along the upper air boundaries of large masses of warm and cold air

  • ( Related graphic: ) During major cold outbreaks over the USA, the jet stream often dives south - staying above the warm-cold boundary - sometimes moving well over the Gulf of Mexico

  • During unusually mild winter weather and during the summer, the jet stream retreats northward into Canada

  • ( Related graphic: ) While the term "jet stream" refers to high-altitude winds, meteorologists also talk about "low-level jet, " which are high-speed winds that might be only a few hundred feet above the surface

    Jet Stream: current of rapidly moving air
    Explains how the jet stream forms between hot and cold air masses.

  • 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

  • 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)

  • During the winter months, Arctic and tropical air masses create a stronger surface temperature contrast resulting in a strong jet stream

  • The yellow, green and red ribbon on the image above represents the jet stream, and along the East Coast, the region of strongest winds (shaded in red) is a

    Contains frequently asked questions, and answers what generates the jet stream.

  • required Inside the Jet Stream by Rick Groleau For the very few of us who will ever pilot a jet at high altitude, deciding whether or not to fly in the fast-moving, eastward-blowing jet stream will be fairly easy

  • So what is the jet stream? And why is it there? Perhaps your image of the jet stream comes from maps broadcast during the weather portion of your local news

  • ('The jet stream will bring such and such weather our way, ' the forecaster might say.) Well, in actuality, the jet stream is a complex phenomenon involving the interplay between many variables

  • (154k) Requires the free What generates the jet stream? Why does it flow from west to east? Find out here

  • (non-Flash version) (435k) The jet stream, rather than being a nicely contained river of air, meanders around the globe in a largely unpredictable way

    Includes how high the jet stream is, how fast it's moving, and how it affects weather.

  • Frequently Asked Questions About The Jet Stream How Would You Define a Jet Stream? The jet stream, one of the most dramatic forces of nature, was discovered during World War II when aviators first tried to cross the Pacific

  • How High? At an altitude above 20, 000 feet, or between 6 and 9 miles above the Earth's* surface, the jet stream winds make their presence known

  • This puts the jet stream near the top of the Earth's, where most of the Earth's weather occurs

  • The greater the contrasts in surface temperature, the stronger the jet stream winds blow

  • Length, Width, and Thickness? Although the jet stream may stretch for thousands of miles around the world, it is only a few hundred miles wide and often less than 3 miles thick

  • Does It Ever Blow North or South? Because the jet stream winds are greatly affected by changes in temperature, their trajectory does not always flow in a uniform west to east direction

  • What Does It Have to Do With Global Ballooning? Most of the teams plan to catch a ride on the jet stream, which will carry the balloons around the Earth

  • In this scenario, the jet stream would propel a balloon on a wavy north-south course, advancing very slowly around the Earth, losing precious time rather than advancing the balloon on an easterly course around the globe

    and where atmospheric phenomena occur.

  • Beyond it the thermosphere , where the air is very thin and molecules move fast (so they are called "hot") but because there is so little air it would feel very, very cold! [94 KB] The jet stream is a current of fast moving air found in the upper levels of the troposphere which blow from west to east due to the Earth's rotation

  • Wind speed within jet streams range from 50 to 300 miles per hour

  • The position of the jet stream denotes the location of the strongest temperature contrasts between different latitudes on the Earth surface

    Looks at the history of nor'easters, and compares them to hurricanes.

  • Nor'easters are spawned by a very curvy Jet Stream that dips far south allowing cold arctic air to meet warm air

  • The Jet Stream plays a very important role also in the strengthening of the storm

  • As the incoming air rises around the center, the Jet Stream whisks it away further increasing the speed of the incoming air

  • Normal Jet Stream winter pattern is to follow the coast and consequently drags the storm northeast ward
