Global Jet Stream Forecast. Welcome to our new interactive global jet stream forecast map here on Netweather. Drag the map around to move it, the mouse wheel will zoom in and out (pinch to zoom on mobile and tablet). The maps update four times a day - and are an initial small feature using this new mapping technology - keep your eye out for. Current United States Jet Stream Observations with Jet Stream readings for across the us nation. The Jet Stream How the earth's rotation effects the west to east direction of the jet stream. 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 streams follow the boundaries between hot and cold air.
Jet streams are narrow bands of strong wind that generally blow from west to east all across the globe. Earth has four primary jet streams: two polar jet streams, near the north and south poles, and two subtropical jet streams closer to the equator. On Earth there are four main jet streams: two polar jet streams and two subtropical jet streams. They form in the atmosphere where warm air masses meet cool air masses.
This movement creates an air current, or wind. A jet stream is a type of air current that forms high in the atmosphere. The Sun heats Earth unevenly, creating masses of colder air near the poles and warmer air near the equator. On average, jet streams move at about miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — miles per hour or faster. Speeds this high usually happen in polar jet streams in the winter time.
Airplanes can fly in the jet stream. Airplanes also fly in the mid to upper troposphere. So, if an airplane flies in a powerful jet stream and they are traveling in the same direction, the airplane can get a boost. A visualization of the Northern Hemisphere's polar jet stream swirling weather patterns from west to east across North America.
The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. However, if a weather system is far away from a jet stream, it might stay in one place, causing heat waves or floods. Jet streams typically move storms and other weather systems from west to east. However, jet streams can move in different ways, creating bulges of winds to the north and south.
With this technology, meteorologists can detect the location of the jet streams. The moving band of air between the two is the polar jet stream. Monitoring jet streams can help meteorologists determine where weather systems will move next. But jet streams are also a bit unpredictable. Their paths can change, taking storms in unexpected directions. So satellites like GOES can give up-to-the-minute reports on where those jet streams are in the atmosphere — and where weather systems might be moving next.
