The Antarctic Blozone hole (the Ozone hole - the large loss of ozone) between July and December is created during the the annual transport of atmosphere from the Northern Hemisphere into the Antarctic vortex region. During the Northern Hemisphere spring and summer periods the tropopause increases in height, elevated by increases in temperature anthropogenic gaseous output. When the NH autumn arrives in late July, the tropopause reduces in height providing an acceration and pressure to the troposphere which promotes additional impetus to the southward movement of vast volumes of atmosphere. Regional cooling in the Northern Hemisphere influences which of the primary transport corridors (Atlantic, Indian or Pacific Oceans) is used. Ultimately the excess air arrives in the low pressure zone of the Antarctic polar vortex where it further compresses, increases in temperature and travels up the outside of the vortex to higher altitudes and then descends down the vortex displacing the ozone. Ozone rises at the continent surface. It is this continuous vertical flow of atmosphere between July and December that dilutes/ blows away/ thins out the ozone in the polar stratosphere. The “ozone hole” is therefore a dilution, not the destruction of ozone.

As I am putting forward an alternative explanation to the current (chlorofluorocarbon) theory, I have used the term Blozone hole as this better describes what is actually occurring, and to separate my theory from the previous.


Blozone hole = an area within the troposphere and stratosphere that acts as an atmospheric pressure or transport valve, resulting in the loss or dilution of ozone.

Blozone breach = an area where the atmosphere in the troposphere is forced to escape through the tropopause into the stratosphere and travel through it causing a dilution and thinning of ozone.
