Polar stratospheric clouds over Western Norway. The stratosphere is very dry; unlike the troposphere, it rarely allows clouds to form.In the extreme cold of the polar winter, however, stratospheric clouds of different types may form, which are classified according to their physical state (super-cooled liquid or ice) and chemical composition.
