Ozone depletion is worse in Antarctica because of the presence of polar stratospheric clouds, which provide a surface for chemical reactions that break down ozone molecules. Additionally, the extreme cold temperatures in Antarctica contribute to the formation of these clouds, making the ozone depletion more severe in this region.
The highest clouds are polar mesospheric clouds, which, at heights from 76,000 to 85,000 m (altitude) are much higher than other types of clouds, such as cirrus and cumulonimbus. Cumulonimbus can exceptionally reach 23,000 m at the very top of a peaked formation, but these clouds normally form mainly within the 2,000 to 16,000 m range. Cirrus clouds, at a maximum height of about 18,000 m in tropical zones, are also much lower than polar mesosphericclouds.
42. ---- The ozone layer is located in the bottom of the stratosphere, so just above the ozone layer is still stratosphere. See the link below to the entry at Wikipedia for the stratosphere, that shows the various layers above the stratosphere (mesosphere, thermosphere, exosphere)
A low level cloud is a cloud that forms below 6,500 feet (2,000 meters) in the atmosphere. These clouds are typically composed of water droplets and are often associated with precipitation. Examples of low level clouds include stratus clouds, cumulus clouds, and stratocumulus clouds.

Polar Stratospheric clouds or PCS's are clouds present in the poles. These act as the base for ozone depleting reactions.
Polar Stratospheric Clouds are called PSC's. They act a catalysts for ozone depletion.
Polar stratospheric clouds or PSC's are formed at cold regions. These form the base for the various ozone depleting reactions at the poles.
Polar Stratospheric clouds are formed at poles. They act as a base for ozone depletion.
It does impact the ozone depletion. They act as a base for the depletion of ozone.
The ozone depletion is worst at the poles. It is due to the low temperature there. The Polar Stratospheric Clouds are formed at the poles.
The breakdown of ozone layer is promoted by the CFC's. PSC's i.e. Polar Stratospheric Clouds also take part in it.
You'll see clouds in Antarctica that you can only see in polar environments, including noctilucent clouds -- electric-blue-coloured, and polar stratospheric clouds or PSCs, also known as nacreous clouds, These clouds are formed very high -- 50,000 to 80,000 feet -- in the atmosphere, and appear due to a mix of ice crystals and meteoric dust. this means that they are not formed the way that most clouds over earth are formed. These clouds form due to sunlight and not to temperature.
Ozone depletion is worse in Antarctica because of the presence of polar stratospheric clouds, which provide a surface for chemical reactions that break down ozone molecules. Additionally, the extreme cold temperatures in Antarctica contribute to the formation of these clouds, making the ozone depletion more severe in this region.
Ozone depletion is particularly related to the polar regions because of the unique climatic and atmospheric conditions found there. During winter, polar regions experience long periods of darkness and extremely cold temperatures, which create polar stratospheric clouds. These clouds enhance chemical reactions that break down ozone molecules. Additionally, polar vortexes (large-scale cyclonic winds) in the stratosphere confine the depleted ozone, resulting in the formation of the infamous "ozone hole."
There are several 'really colorful' events in the skies over the Antarctic continent, in addition to sunlight, starlight and moonlight. When the sun is up, you can see sun dogs, that Wikipedia describes as: "... the scientific name parhelia (singular parhelion), are an atmospheric phenomenon that creates a pair of bright spots of light on either side on the sun, often co-occurring with a luminous ring or halo." Sun dogs are also visible in less polar, but high-latitude geographies on earth. When there is no sun, Aurora Australis are visible during the dark periods, and from Wikipedia: "The aurora is produced by solar wind particles guided by Earth's field lines to the top of the atmosphere." When there have been no sunrises, once the sun does rise -- once again from Wikipedia, below -- "Polar stratospheric clouds or PSCs, also known as nacreous clouds, are clouds in the winter polar stratosphere at altitudes of 15,000 to 25,000 meters (49,000 to 82,000 ft)."
The thinning of ozone layer is most pronounced at the poles of the earth. It is because of the low temperature of the low temperature there. The ozone depleting reactions are carried on the polar stratospheric clouds i.e. the PSC's. these PCS's require minimum temperature for their formation which is possible only on the poles.
