Erl Happ explains: To understand how climate evolves we have to comprehend the ‘ozonosphere’.

NOT A LOT OF PEOPLE KNOW THAT

In the 1920’s the inventor of the Dobson Spectrometer designed to measure ozone in the atmosphere, Gordon Dobson, quickly discovered that total column ozone maps surface pressure. Low pressure cells generated in high latitudes have fewer molecules in the atmospheric column because the upper portion is ozone rich, ozone absorbs infrared radiation from the Earth and the upper air is therefore more rarefied. The reduction in density aloft fully, and in fact over-compensates, for the coldness and density of the air at the surface. By contrast High pressure cells are dense above and relatively less dense below because they originate in the warmer ozone poor mid latitudes.

The ozone content of the air varies on all time scales.

Because the distribution of ozone is a secondary determinant of atmospheric pressure (along with the absorption of radiant energy from the sun as the primary determinant) its distribution is allied to wind…

  1. The emphasis on ozone is similar to mine but differs in certain respects.

    Only time and observations will indicate which approach is the more accurate.

    Ozone holes are localized and seasonal events and they do not constitute evidence of ozone depletion on a global scale as claimed by the UNEP in the Montreal Protocol. Please see
