Rising temperatures affect jet streams' power, location

By Richard Brill

POSTED: 01:30 a.m. HST, May 16, 2014

~~<p>A jet stream is a river of high-speed, high-altitude air thousands of miles long, a few hundred miles wide and a few miles thick flowing between six to nine miles above the earth's surface.</p>
<p>There is a polar jet and a higher-altitude, slower-moving tropical jet in each of the Northern and Southern hemispheres around latitudes 30 degrees and 60 degrees. The winds of the jets travel from west to east near the tropopause, the interface between the troposphere and the stratosphere. Jet streams flow along the boundaries between continent-size air masses that generally coincide with the subtropical highs and the polar front, but a jet can break off into smaller rivers of air that might merge again downstream or fade away completely.</p>

A jet stream is a river of high-speed, high-altitude air thousands of miles long, a few hundred miles wide and a few miles thick flowing between six to nine miles above the earth's surface.

There is a polar jet and a higher-altitude, slower-moving tropical jet in each of the Northern and Southern hemispheres around latitudes 30 degrees and 60 degrees. The winds of the jets travel from west to east near the tropopause, the interface between the troposphere and the stratosphere.
