In order for rapid ozone destruction to happen, clouds (known as PSCs, Stratospheric Clouds, Mother of Pearl, or Nacreous Clouds) have to form in the ozone layer.
Without the clouds, there is little or no ozone destruction. Only during the Antarctic winter does the atmosphere get cold enough for these clouds to form widely through the centre of the ozone layer.
Elsewhere the atmosphere is just too warm and these clouds don't form in the ozone layer.
The northern and southern hemispheres have different 'weather' in the ozone layer, and the net result is that the temperature of the Arctic ozone layer during winter is normally some ten degrees warmer than that of the Antarctic. This means that such clouds are rare, but sometimes the 'weather' is colder than normal and they do form. Under these circumstances significant ozone depletion can take place over the Arctic, but it is usually for a much shorter period of time and covers a smaller area than in the Antarctic.

U people are so gullible ,did u go to school. The holes at the poles if u buy the hoax that it is eaten by the CFC.
The holes occur at the poles at a precis time every year. If the CFC are doing it the CFC molecules haft to get together at The precise time every yr. and make a mad dash for the4 poles. The solar winds are ionized particles and the electrons or bata particles are attracted to the north pole so it is negative. The south pole attracts the alpha particles making the south pole positive. this is tremendous voltages and current. It's yearly appearance is due to the tilt of the earth. The hole in the south pole is more pronounced because the alpha particles are much heaver. This charge across the earth creates the ionized shield around us that protects us from radiation.

As carbon dioxide is released into the atmosphere, it reacts with the ozone molecules and breaks them up in a chain reaction. The hole shows up at the poles because the spin of the earth pulls these gases to the poles where they react to break up ozone.

I am not really sure, but I believe it is because the magnetic field and the other fields that all meet at the poles.
