Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into … See more The strongest jet streams are the polar jets around the polar vortices, at 9–12 km (5.6–7.5 mi; 30,000–39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10–16 km (6.2–9.9 … See more Polar jet streams are typically located near the 250 hPa (about 1/4 atmosphere) pressure level, or seven to twelve kilometres (23,000 to 39,000 ft) above sea level, … See more Hurricane protection The subtropical jet stream rounding the base of the mid-oceanic upper trough is thought to be one … See more Effects of ENSO El Niño-Southern Oscillation (ENSO) influences the average location of upper-level jet streams, … See more The first indications of this phenomenon came from American professor Elias Loomis in the 1800s, when he proposed a powerful air current in the upper air blowing west to east across the United States as an explanation for the behaviour of major storms. … See more In general, winds are strongest immediately under the tropopause (except locally, during tornadoes, tropical cyclones or other anomalous … See more On Earth, the northern polar jet stream is the most important one for aviation and weather forecasting, as it is much stronger and at a much lower altitude than the subtropical jet … See more WebLearn About 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 …

WebWelcome 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 … WebWhen the jet stream gets particularly wavy, meteorologists call it a meridional pattern because air flow is mostly parallel to meridians (lines of longitude) in some areas. In meridional patterns, areas of divergence (and convergence) aloft become more pronounced, which favors the formation of more intense mid-latitude cyclones.
