The correlations between the total column ozone abserved by TOMS and the
11-yr sunspot cycle are lowest in the equatorial region, where ozone is
produced, and in the subpolar regions, where the largest amounts are found.
In the annual mean the highest, statistically significant, correlations lie
between the 5° and 30° parallels of latitude in either hemisphere --
between the area of production and the areas of plenty. This position of the
largest correlations suggests that the association between the Sun and the
ozone is not a direct, radiative one, but that it is due to solar induced
changes in the transport of ozone, that is, to changes in the
atmospheric circulation. The highest tropical-subtropical correlations move
with the Sun from summer hemisphere to summer hemisphere.
