- Jet Streams extended definition. Jets are fast moving ribbons of air high up in the atmosphere. They are responsible for transporting highs and lows. They affect precipitation and temperatures, and they mark boundaries between massive air masses.

- A: The jet stream is a high-altitude river of fast-moving air with wind speeds of 57 mph or greater. The two main jet streams that influence the USA's weather are the polar jet and the subtropical jet stream. A front is a boundary between different air masses.

- The Gulf Stream is a powerful western boundary current in the North Atlantic Ocean that strongly influences the climate of the East Coast of the United States and many Western European countries.

- The east coast of the United States is affected mainly by the Gulf Stream current, which brings warm water from the tropics into higher latitudes. The warm current flows north along the coast towards Maine, before veering northeast out toward England.

Jet stream View Radar, Satellite, Temperature, Snow Cover, Storms and more by zooming directly over your area. 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.

- The Gulf Stream is a powerful western boundary current in the North Atlantic Ocean that strongly influences the climate of the East Coast of the United States and many Western European countries.Click the image for a larger view.here are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).

How does the Jet Stream affect the weather in...? Best Answer: The Jet Stream are very strong westerly winds at the top of the troposphere and right over the polar front. It doesn't affect only Grand Rapids but most of the temperate north and south hemisphere.They are a kind of horizontal tornado that results from the kink in the tropopause and the Coriolis effect. need to figure out how the jet stream affects the weather in Grand Rapids, MI.

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).

Jet Streaming Along the Polar Front Jet Streaming Along the Polar Front. The polar front and its associated jet stream have a major influence on the weather conditions surrounding it. Many storms form along the polar front in the vicinity of the jet stream's maximum winds. Because of the association of the jet stream with the polar front, media weather maps often include the jet stream's position as a rough indicator of continental divisions between warm and cold air masses. Here is why.

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).

Jet stream What direction does the jet stream flow. The jet stream flows from west to east. 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.

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.

Major climate factors The higher your elevation, the cooler the temperatures will be, in both winter and summer. The growing season is usually shorter, as well. Jet streams. The strong, fast high-altitude air currents known as jet streams affect climate by picking up air of all types--moist, dry, warm, cold--and carrying it to other areas.

The Effects: Economy Nutrient pollution can have severe economic impacts on recreational fishing, businesses, and tourism. Nutrient pollution causes millions of dollars in losses to the commercial fishing industry. Nutrient pollution has diverse and far-reaching effects on the U.S. economy, impacting tourism, property values, commercial fishing, recreational businesses and many other sectors that depend on clean water. Nitrates and algal blooms in drinking water sources can drastically increase treatment costs.

- . 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).

- Surface ocean currents are primarily affected by wind patterns. Trade winds can push water along the top of the ocean and aid in the formation of surface currents. One example of a wind-driven circulation affecting an ocean current is the Gulf Stream.ncreasing carbon dioxide levels in waters and warmer water temperatures impact global ocean circulations, which are one of the primary drivers of weather, temperature, precipitation, and seasons, and therefore affect a variety of aspects of health. 1,2.

The Jet Stream: What It Is and How It Affects Our Weather 1 In North America, the polar jet is more commonly known as the jet or the mid-latitude jet (so-called because it occurs over the mid-latitudes). 2  The Subtropical Jet. 3  The subtropical jet is named for its existence at 30°N and 30°S latitude--a climate zone known as the subtropics.

Jet Streams Figure A: Jet Stream Wind Speeds. Image from NOAA. Jet streams are the major means of transport for weather systems. A jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep. Jet streams usually sit at the boundary between the troposphere and the stratosphere at a level called the tropopause.

Ocean Conveyor Belt Impact Ocean surface currents redistribute heat around the world and have a profound effect on the world’s climate. Nowhere is this clearer than in the North Atlantic Ocean. The Gulf Stream and the North Atlantic Current ferry huge volumes of warm salty tropical water north to the Greenland coast and to the Nordic Seas.

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.

Icelandâs Climate Moves with the Gulf Stream Flow Changes in the Gulf Stream effect changes in Iceland’s climate. A strong Gulf Stream warms the North Atlantic Drift which flows along the southeast coast of Iceland, and keeps the west side of the island a few degrees warmer than the northeast side, which is cooled by the Iceland and Greenland ocean currents flowing from the Arctic.
