Polar stratospheric cloud - Wikipedia
Polar stratospheric clouds (PSCs) are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are best observed during civil twilight, when the Sun is between 1 and 6 degrees below the horizon, as well as in winter and in more northerly latitudes. [1] .
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. These high altitude clouds form only at very low temperatures help destroy ozone in two ways.
Polar Stratospheric clouds - Vajiram & Ravi
Recently, weather watchers have captured images of rare Polar stratospheric clouds over Scotland, northern England and the West Midland. These are also known as nacreous clouds or mother of pearl, due to their iridescence.
Ultra-rare 'rainbow clouds' light up the Arctic Circle like auroras in ...
Rare clouds that give off bright, multi-colored light like an aurora were recently spotted at multiple locations in the Arctic. But what causes them?
Polar Stratospheric Clouds: Satellite Observations, Processes, and Role ...
We provide a new vortex-wide climatology of polar stratospheric cloud occurrence and composition based on 21st century satellite data. We review advances in understanding cloud formation, the role of dynamical processes, and heterogeneous chlorine activation
Spectacular 'rainbow clouds' light up northern skies in a rare ...
Nacreous clouds also known as polar stratospheric clouds have been appearing across northern skies. We've rounded up some of the best photos of these rare 'rainbow clouds'.
New Insights into Polar Stratospheric Clouds - Eos
New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
Polar stratospheric clouds - Australian Antarctic Program
Polar stratospheric clouds over Davis PSCs form poleward of about 60°S latitude in the altitude range 15–25 km during the winter and early spring. The clouds are classified into Types I and II according to their particle size and formation temperature.
