The Polar Vortex
In the Arctic, during the polar night, the atmosphere at altitude around 24 km remains confined and will form during the winter a very large vortex, called the polar vortex, almost as large as the polar cap. During the lesson you will find more about polar vortex phenomena. You will get familiar with such terms as stratoshere, ozone hole and ozone layer. We will publish Polarpedia terms for this lesson soon.
