Abstract:
In this paper, main results concerning ozone over the Tibetan Plateau in last decade were reviewed. Some important advances are summarized as follow: (1) A fact is found that there exists a low center of total column ozone over the Tibetan Plateau in summer; (2) The analysis and diagnosis of observation data show that the Tibetan Plateau is one key channel by which pollutants from the surroundings of the Tibetan Plateau can be transported into low stratosphere; (3) The Tibetan Plateau is one of three regions of the rapidest decrease of total ozone at the same latitude; (4) The analysis of the atmospheric circulation and modeled results indicate that the formation of low center of total column ozone over the Tibetan Plateau is primarily ascribled to the special circulation of the Tibetan Plateau and its surroundings. In the formation process, dynamic process plays main role, and chemical process is the secondary. Moreover, the chem ical process part ly of fsets the dynamic role. (5) The trend of total column ozone over the Tibetan Plateau is predicted by model.
