What is a Jet Stream? Live Science

WebbThe polar jet stream is located near the polar front about 10 km up, near 50° to 60° latitude. The difference in height of these jets is due to their location at the tropopause, and the fact that the tropopause is found higher in tropical regions than in polar regions due to average layer temperature differences of the troposphere underneath. WebbThe effects of Arctic warming and sea ice loss on the polar jet stream aren’t fully understood, but it’s possible that more frequent visits of polar air to mid-latitudes could occur as a result of these changes. Mid-latitude extreme cold events will continue to happen because of natural variability in the climate system. rbm ministries incWebbför 2 dagar sedan · 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.
