Polar stratospheric cloud - Wikipedia
Polar stratospheric clouds or PSCs, also known as nacreous clouds (/ ˈ n eɪ k r i ə s /, from nacre, or mother of pearl, due to its iridescence), are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 meters (49,000–82,000 ft).
Polar Stratospheric Clouds | NASA
Scientists recently discovered that polar stratospheric clouds, long known to play an important role in Antarctic ozone destruction, are occurring with increasing frequency in the Arctic.
Polar Stratospheric Clouds - The Ozone Hole
Polar Stratospheric Clouds. The colorful clouds near the top of this picture are Polar Stratospheric Clouds (PSCs). The PSCs are flying high above the darker cirrus clouds at the bottom of the picture.
Polar Stratospheric Clouds
One explanation for the decrease in the equator to pole temperature difference (EPTD) during equable climates examines the influence of polar stratospheric clouds (PSCs) on longwave radiation leaving the Earth in the high-latitudes and, as a result, on temperatures near the poles. In contrast to ...
Nacreous and Polar Stratospheric Clouds
Nacreous clouds are wave clouds. They are often found downwind of mountain ranges which induce gravity waves in the lower stratosphere. Their sheet-like forms slowly undulate and stretch as the waves evolve. The clouds can also be associated with very high surface winds which may indicate the ...
Ozone's Problem with Polar Stratospheric Clouds
Ozone's Problem with Polar Stratospheric Clouds Using a GIF animation, this page describes in detail the processes by which ozone is destroyed over Antarctica by polar stratospheric clouds during the austral spring.
Polar stratospheric clouds — Australian Antarctic Division
Polar stratospheric clouds (PSCs) play a central role in the formation of the ozone hole in the Antarctic and Arctic. PSCs provide surfaces upon which heterogeneous chemical reactions take place.
