  Polar stratospheric clouds: nacreous

  Nacreous clouds are seen here from an aircraft climbing through approximately 9 000 m (30 000 ft) over northern Norway.

  These polar stratospheric clouds are composed primarily of ice and are characterized by brilliant iridescent colours and a lenticular shape.

  Nacreous clouds only form in the stratosphere and in the high latitudes of both hemispheres during their respective winter seasons.
