Why is the hole in ozone above Antarctica where no one lives. Why is it not above some polluted area?

Question

Human interference has created the hole then, why is the hole so far away from humans?

Answer 1

Reactions that take place on polar stratospheric clouds (PSCs) play an important role in enhancing ozone depletion[3]. PSCs form more readily in the extreme cold of Antarctic stratosphere. This is why ozone holes first formed, and are deeper, over Antarctica

Answer 2

We live in a layer of atmosphere called Troposphere. This is what we breathe and where weather happens and stuff. Above that is the stratosphere where the ozone layer is. These two layers are pretty distinct, and are seperated by an isothermal layer so they don't get all mixed up - they remain seperate because of their temperatures and radiation from the sun.

in Antarctica sometimes they have winters where there is no sunlight, and in this situation lots of gases can rise from the troposphere to the stratosphere, including pollutants, so the ozone hole is made.

Answer 3

The ozone layer is created by the solar winds reacting with the magnetic fields. The deplition of the ozone (size of the hole) changes on a daily basis. I have not heard a good explaination for this. Laboratory studies do show that cfc's will react with ozone and break it down to regular oxygen.

Answer 4

The ozone layer is way up in the atmosphere (10 to 50 km; 6 to 30 miles) and anything getting up there by winds has plenty of time to get pushed around.

The winds of the upper layers of the atmosphere tend to push the ozone-destroying compounds to the poles, and push the ozone away. It's natural for there to be less ozone near the poles during certain portions of the year; this effect has been heightened

Answer 5

It takes decades for CFC's to build up in the atmosphere to have a significant effect. The air gets mixed up all over the world in that time so the CFC concentration is pretty much uniform. Ozone depletion due to CFC's, however, is accelerated over Antarctica because O3 depletion is catalyzed on the surface of high altitude ice crystals, which form in the ozone layer there. That makes it like the proverbial canary in the coal mine.
