The Arctic Circle clouds, known as polar stratospheric clouds (PSC), only form when the lower stratosphere reaches temperatures below minus 114 degrees Fahrenheit (minus 81 degrees Celsius ...

Type II polar stratospheric clouds (PSCs) are known as one of the most beautiful cloud types in Earth's repertoire, appearing above the Arctic and Antarctic as softly glowing whisps with a ...

Nacreous clouds, or ice polar stratospheric clouds, are a rare type of cloud that forms in very cold conditions and at high altitudes. They are known for their iridescent colors, which are created ...

Weather How large is ice cloud formation in the stratosphere and why doesn't this ice fall? I had a student ask me, and I wanted to find the answer for him.

Nacreous clouds are highly iridescent clouds that form in the stratosphere at extremely low temperatures of around negative 85 degrees Celsius. Scientifically, ...

“This water vapor then travels upward into the stratosphere, and helps to form polar stratospheric clouds,” or PSCs for short.

The multi-colored clouds are known as polar stratospheric clouds (PSCs) and look similar to auroras blazing in the sky. However, these rainbow clouds aren't auroras as you might think.

Stratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, find researchers from UNSW Sydney. November 8 ...

Arctic observers got a rare festive treat when rainbow-colored clouds appeared in the skies. So-called polar stratospheric clouds were seen over Norway, Sweden, Finland, Alaska, and Scotland.

Known as polar stratospheric clouds, rainbow clouds exist at very high altitude (around 70,000 ft) within the Earth's stratosphere. Clouds do not normally form in the stratosphere due to its ...

Known as mother-of-pearl clouds due to their iridescent rainbow sheen, polar stratospheric clouds are a rare atmospheric phenomenon that form under extremely cold temperatures—below minus 108 ...
