How are jet streams created
WebThe Tropical Easterly Jet ( jet stream) is the meteorological term referring to an upper level easterly wind that starts in late June and continues until early September. This strong flow of air that develops in the upper atmosphere during the Asian monsoon is centred on 15°N, 50-80°E and extends from South-East Asia to Africa. WebBy cutting down on the flight time, jet streams help in cutting down costs for the airline industry. A phenomenon known as clear-air-turbulence (CAT) is often associated with jet streams, it is caused by vertical and horizontal wind shear. The CAT is at its strongest on the cold air side of the jet and just under the axis of the jet.

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 one … Ver mais 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 … Ver mais 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, while the weaker subtropical jet streams are much higher, between 10 and 16 kilometres … Ver mais Hurricane protection The subtropical jet stream rounding the base of the mid-oceanic upper trough is thought to be one of the causes most of the Hawaiian … Ver mais Effects of ENSO El Niño-Southern Oscillation (ENSO) influences the average location of upper-level jet streams, and leads to cyclical variations in precipitation and temperature across North America, as well as affecting tropical cyclone development … Ver mais The first indications of this phenomenon came from American professor Elias Loomis in the 1800s, when he proposed a powerful air current … Ver mais In general, winds are strongest immediately under the tropopause (except locally, during tornadoes, tropical cyclones or other anomalous situations).
