Polar stratospheric cloud - Wikipedia
A polar stratospheric cloud (PSC) is a cloud that forms in the winter polar stratosphere at altitudes from 15,000 to 25,000 m (49,000 to 82,000 ft). They are best observed during civil twilight , when the Sun is between 1° and 6° below the horizon , as well as in winter and in more northerly latitudes. [ 1 ]
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: All you need to know
Polar stratospheric clouds (PSCs) form during winter months in the Polar Stratosphere region at altitudes ranging from 15000-25000 meters. PSC appear as beads or patches of pearl fused into the bright sky mostly before sunset.
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.
Polar Stratospheric Cloud - NASA
An image of a polar stratospheric cloud has been chosen for our front page because many atmospheric chemistry research projects at JPL are focused on understanding the properties of these clouds and the consequences of their existence.
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: 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
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.
