   Sep 20, 2023 · Why the jet stream moves from west to east. Based upon the Earth's circumference at different latitudes, the velocity at which we at the surface move east in a 24-hour rotation decreases from over 1,000 mph (1,600 km/h) at the equator to zero at the poles.

   How fast do jet streams blow?

   • Their winds blow from west to east at speeds that range from 80 to 140 miles per hour, but they can reach more than 275 miles per hour. Jet streams are stronger in winter because that's when the air temperature differences that drive them tend to be the biggest.

   How fast can a polar jet stream travel?

   • The polar jet stream can travel at speeds greater than 180 km/h (110 mph). Here, the fastest winds are coloured red; slower winds are blue. Clouds along a jet stream over Canada. Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of the Earth, Venus, Jupiter, Saturn, Uranus, and Neptune.

   How high is a jet stream?

   • In terms of altitude, jet streams usually occur between 23,000 and 39,000 feet (7,000 to 12,000 meters) above the Earth’s surface. Each jet streams stretches for thousands of miles, but is only about 3 miles thick and a few hundred miles wide. Jet streams are strongest in the winter because temperature contrasts are greater.

   How does a jet stream affect a storm?

   • 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. Storms tend to follow the edge of the jet stream, where the difference between cool and warm air creates the turbulent conditions for storms.

   Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of the Earth, Venus, Jupiter, Saturn, Uranus, and Neptune. 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 ...

   6 days ago · On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster. Speeds this high usually happen in polar jet streams in the winter time.
