Variation of Dynamical Processes and Ozone in the Stratosphere and their Role in Climate

本课题组承担国家重点领域科研资助项目“平流层动力过程与臭氧的变化及其对气候的作用”的管理任务，活跃的中层大气科学家分为以下4个课题组；(1)平流层臭氧与大气环流的变化；(2)从次要成分时空变化推断的平流层-对流层耦合；(3)大气环流化学模式的建立与平流层物质输送的研究；(4)本项目大尺度波相关物质输送及其季节和年际变化。为了协调整个小组的研究，及时发表研究成果，并与其他不属于我们研究项目的研究人员进行讨论，我们召开了8次行政会议，一次全体会议，6次公开研讨会。特别是2002年11月12日至15日召开的“平流层变化与气候国际研讨会”。共有96位科学家（其中9个国家的27位）参加了会议，发表了60多篇论文，其中包括21篇受邀论文，讨论非常活跃和有启发性。出版了一本扩展摘要集。除了这些活动，我们还建立了网站，出版了4期通讯来宣传我们的活动。今年我们申请了由文部省资助的“2003年公共研讨会”，并得到了非正式的批准。

This research group has administrative function for the research project "Variations of Dynamical Processes and Ozone in the Stratosphere and Their Role in Climate" under the Grant-in-Aid for Scientific Research on Priority Areas, and active middle atmosphere scientists are organized to form following four groups ; (1) Variations of Stratospheric Ozone and General Circulation of the Atmosphere, (2) Stratosphere-troposphere coupling inferred from the space-time Variation of minor constituents, (3) Development of general circulation model with chemistry and studies on stratospheric material transport, (4) Material transports associated with large-scale waves and their seasonal and interannual variations under this project.Aiming to coordinate researches of whole groups, to publish research results promptly, and to make discussions with other researchers who do not belong to our research project, we held administrative council 8 times, a general meeting, and public symposiums 6 times.In particular, the "International Symposium on Stratospheric Variations and Climate" was held in November 12-15, 2002. A total of 96 scientists (27 were from 9 foreign countries) participated, and more than 60 papers including 21 invited papers were presented, and very active and stimulating discussions were done. An collection of extended abstracts was published.In addition to these activities, set-up of Web site and publication of 4 issues of newsletter were done to publicize our activities. In this year we have applied to "Public Symposium", 2003 that is held under the aid by MEXT, and it is informally approved.
