| Title: | The Jet Stream and Rossby Waves. |
| Caption: | This animation shows the polar jet stream and the course of the westerlies. It demonstrates the formation and movement of Rossby waves and how the polar jet stream separates cold arctic/continental air from warmer air farther south. The animation ends with the pinching off of a low-pressure cold air mass over Canada. |
