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.

The Gulf Stream The Gulf Stream is, essentially, a 40-50 mile wide current that runs through the Atlantic Ocean, but its breadth and speed can categorize it more accurately as a river. Like all other currents throughout the world, the Gulf Stream is formed by the sun, the wind, and the water.

Why do airplanes leave the white stream behind them sometimes and not other times? This blog has an explanation of contrails that should answer your question: http://privatejetcharter.spaces.live.com... the white stream is a vapor trail..also sometimes call a chemtrail.. they are caused by pollutants given off from jet engines..note you never see them behind propeller driven aircraft.

Module 9 / Westerlies and the Jet Stream Introduction. The polar-front jet stream is like a high-speed river of air in the upper atmosphere. It separates warm and cold regions at the Earth's surface. It may be several hundred kilometres across from north to south, 1,500 to 3,000 meters thick and at an altitude of 9,000 to 13,000 meters.

- … A    The smoke trails that appear behind other aircraft are actually known as con-trails and are in fact water vapour. The warm moist air that comes from the jet mixes with the cold air in the sky. It creates a condensation trail or con-trail.   Con-trails are also generated on the aircraft's wingtips. Again, this is simply moisture that is generated.When the air flows OVER the wing, it has to travel further and therefore it speed up.ome jet fighters also have special designed wings and wing tips that will create contrails in a tight turn that earlier aircraft could not perform. Thus the F-18 can fly very low and still produce contrails.

- Figure 8.14 Jet stream winds and surface systems. Recall that surface air converges and rises in low pressure systems. To maintain low pressure at the surface the rising air must diverge at the top. It is this upper air divergence in the jet stream that pulls air upward to help form surface cyclones.In so doing, surface cyclones tend to follow the path of the jet stream.Figure 8.14 shows the relationship between upper-level flow and surface pressure systems.eather Systems Surface Cyclones and the Jet Stream Above the polar front lies the polar front jet stream, a zone of faster moving air in the upper troposphere. The jet stream takes on a meandering pattern with regions of faster and slower air. Within the jet stream there are regions air convergence and divergence.

Jet stream Meteorologists use the location of some of the jet streams as an aid in weather forecasting. The main commercial relevance of the jet streams is in air travel, as flight time can be dramatically affected by either flying with the flow or against the flow of a jet stream.et streams are fast flowing, narrow air currents found in the atmosphere of some planets, including Earth. The main jet streams are located near the altitude of the tropopause. The major jet streams on Earth are westerly winds (flowing west to east).

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.

What Is a Jet Stream? The jet stream, of course! A jet stream is a thin current of air that's several thousand miles wide and several thousand miles long. They're found almost seven miles up in the atmosphere where the troposphere meets the stratosphere at a point called the tropopause. Let us explain.

JetStream Max:The Lightning Process: Keeping in Step JetStream Max: The Lightning Process: Keeping in Step. Lightning can be divided into two types: Flashes with at least one channel connecting the cloud to the ground, known as cloud-to-ground discharges (CG); and. Flashes with no channel to ground, known as in-cloud (IC), cloud-to-cloud (CC), or cloud-to-air (CA).

- The sea breeze circulation is comprised of two opposing flows; one at the surface (called the sea breeze) and one aloft (which is a return flow). These two flows are a result of the difference in air pressure between the land and sea generated by the sun's heating. At the surface, the sun warms both the ground and ocean at the same rate. However, since the heat in the ground is not absorbed well it returns it heat to warm the air.

- Wind velocity is highest in the core of the polar jet stream where speeds can be as high as 300 kilometres per hour. The jet stream core is surrounded by slower moving air that has an average velocity of 130 kilometres per hour in winter and 65 kilometres per hour in summer.

Geography for Kids At the core of the westerly winds lies what scientists call a jet stream. Jet streams are super high-speed winds. Each hemisphere’s westerly has two main jet streams. Closer to the poles we find the polar jet stream.

www.pulse-jets.com For one thing, efficiency has many forms. A study of those forms on the parallel cases of the pulsejet and the turbojet will sometimes yield unexpected results. But, let us first make clear what we are looking for. A jet engine is a machine that increases the momentum of air stream.

Two trails from Two Rivers On Lake Michigan, bicyclists ride the breezes between a lighthouse and a submarine. The Mariners Trail follows Lake Michigan between Two Rivers and Manitowoc. In summer, overheated tourists head for the Cool City. Two Rivers, Wis., gets its nickname from cooling breezes that come from three sides: the East Twin River, the West Twin River and Lake Michigan.

- The jet stream is a river of fast flowing air at high. altitudes above the earth that generally flows from. west to east over the mid-latitudes. To be called a. jet stream the winds should be faster than 57 mph, but the term is. often wrongly used for all upper-level winds. Usually, the jet stream.

- The Jet Stream map shows today's high wind speed levels and jetstream directions. Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth. They form at the boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air to the south.

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.

- The Gulf Stream is one of the strong ocean currents that carries warm water from the sunny tropics to higher latitudes. The current stretches from the Gulf of Mexico up the East Coast of the United States, departs from North America south of the Chesapeake Bay, and heads across the Atlantic to the British Isles.

- 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.
