On the Theory of Annual Variation and Meridional Distributin of Ozone

[摘要] The mass distribution of atmospherie ozone on the earth was calculated assuming that distributions of ozone on the northern and southern hemispheres are approximately the same only with half a year difference of phase. Results showed that the total mass of ozone is always constant. On the other hand, calculated amount of ozone by our previous theory decreases rapidly with increasing sec z. Therefore, meridional distribution of photochemically formed ozone and that observed are quite different, but the total mass is equal to the latter and it becomes also constant on the whole earth. We considered that initial distributions are decided photochemically and actual distributions are formed secondly by pole-ward transports of ozone in the stratosphere. The speed and direction of the transport and their seasonal variations were estimated by which the annual and meridional variation of ozone could be explained reasonably.
