Abstract
For the purpose of discussing the seasonal variation of total ozone amount, the authors assume that the observed total amount of ozone consists of two components. One corresponds to the photochemical equilibrium, the other will be related to the effects of atmospheric circulations. In this paper the former will be called Effect A and the latter Effect B.
The obtained results indicate that Effect B is most active in winter and that its activity increases with latitude and moreover that its hemispheric pattern is similar to that of ultra-long waves. It follows that Effect B has correlation with the activity of the transport of ozone. On the other hand, the magnitude of Effect A is of the same order as Effect B. This result suggests that the contribution of the photochemical effect to the annual variation of ozone seems to be greater than the one expected from the dry theory of ozone. Consequently the wet theory is more acceptable than the dry one.
As mentioned above, the total amount of ozone is assumed to be the sum of two components. Therefore the annual variations of total ozone amoount at a latitude vary according to the magnitude of Effect B because that of Effect A is defined as a function of latidude. In other words the larger
