Abstract

This work is based on the results obtained in the authors' previous work [2], where it was demonstrated that the behavior of the CO2 concentration series in the neighborhood of their extreme values is a steady statistical characteristic of the biotic component. A much larger database is used to study similar statistics to which at a given observation station corresponds the month of maximum (minimum) CO2 concentration in certain years. It is shown that these statistics allow us to single out and to estimate the field specificity of the CO2 concentration in the Northern and Southern hemispheres against the background of effective interhemispheric mixing. In the Northern Hemisphere the month when the minimum mean monthly CO2 concentration is reached is a rather stable characteristic, while for the Southern Hemisphere such stability is not observed; the month when the maximum mean monthly CO2 concentration is reached is not a statistically stable characteristic. This instability is more often observed at high latitudes of both hemispheres.
