Illustration showing a stable southern polar jet stream (green line). Jet streams are fast flowing high-altitude narrow air currents that circle the Earth. They can have a major influence on the weather. When stable, they keep cold air (blue) in, and hot air (red) out of, the polar regions. For a labelled version of this image see C057/3787. | |
