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]
Polar Stratospheric Clouds Explained: 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. PSCs appear as beads or patches of pearl fused into the bright sky, mostly before sunset.
Polar Stratospheric Clouds - Atmospheric Optics
This article explores the captivating phenomenon of Polar Stratospheric Clouds, examining their characteristics, formation, and role in the atmosphere, while also discussing the link between climate change and these beautiful clouds.
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 - Harvard University
PSCs are clouds that form when water vapor enters the stratosphere and when temperatures are cold enough for water vapor to condense there. During the winter, the high latitudes receive very little to no solar radiation, so temperatures drop significantly during this period, known as polar night.
Polar stratospheric clouds - Australian Antarctic Program
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.
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 (PSCs) | Research Starters - EBSCO
Polar stratospheric clouds (PSCs), also known as nacreous clouds, are unique atmospheric phenomena that form in the lower stratosphere at altitudes between 15 and 25 kilometers, particularly in high-latitude regions during winter.
