In this paper the grid data of total ozone mapping spectrograph (TOMS) installed on Nimbus 7 satellite (1978 to 1994) was used and the spatial and temporal distribution of total ozone over China was analyzed. The research indicates that the Qinghai Tibet Plateau destroyed the latitudinal distribution of total ozone of China and the low value closed center emerged over Qinghai Tibet Plateau. Long time change trends of seasonal total ozone of Qinghai Tibet Plateau are provided. It shows that the most obvious decrease of total ozone occurs in winter (Jan.), then in summer (Jul.), the relevant slow change occurs in autumn (Oct.) and spring (Apr.).

We investigated the relationship between solar activity, total ozone, and solar ultraviolet B (UV-B) radiation from the perspective of multi-fractality. Fractal properties are observed in the time series of the dynamics of complex systems. To detect the changes in fractality, we performed a multifractal analysis using a wavelet transform. The changes in fractality indicated that solar activity was closely related to the total ozone and that the total ozone had a strong effect on UV-B radiation. For high solar activity, the F10.7 flux and global total ozone exhibited monofractality. The F10.7 flux and total ozone also increased, and a change from multifractality to monofractality was observed. This corresponded to the formation of the order. The strong interactions between the solar flux and ozone occur during the high solar activity. In contrast, UV-B radiation increased and showed multifractality, when fluctuations in UV-B radiation became large. For low solar activity, the F10.7 flux and total ozone exhibited multifractality, and UV-B radiation exhibited monofractality. Hence, the change in fractality of the F10.7 flux and total ozone was the opposite of UV-B radiation. A significant change in fractality for F10.7 flux and SSN, which had a significant fluctuation and a slight change in fractality for UV-B radiation, and total ozone were identified.

By using the observational O3 data of Kunming and Hong Kong during the period of 1997 – 2001, the paper studies the distribution and variation of total ozone in low latitude region of China. The study shows that the characteristics of variation in Kunming and Hong Kong are very similar, and the total ozone in the western areas is larger than in the eastern ones. It is maximum in summer and minimum in winter.

Bused on January 1962-October 1993 mean value series of monthly mean temperature anomalies of 16 Antarctic stations on 10 standard isobanc surfaces from the surface to the 30 hPa,long term trends and periodic features of climate changes from the troposphere to the lower stratosphere over the Antarctic region are investigated by maximum entropy power spectrum analysis,and the relation between climate change of the stratosphere (troposphere) and tolal ozone (southern 500 hPa circulation) is discussed.
