If refrigerant reacts with/eats away at the ozone layer, why is there such a big hole in the ozone layer above Antarctica?

[โ€“] [email protected] 7 points 1 month ago

Gases we emit into the atmosphere are well mixed over the whole globe in a relatively short time span over a few years or faster. So these refrigerants are in the same concentration over Antarctica as over inhabitated land. However, the ozone depletion effect of the gases is dependent on a lot of factors. One of them are stratospheric clouds, which seem to be one reason for the hole above Antarctica.
