2020年亚洲许多地区经历了或正在经历不同寻常的雨季：5月，印度东北和孟加拉发生强降雨；6月开始，中国华南、西南和江淮流域等地区发生暴雨，引发洪涝灾害；7月初，日本熊本地区暴雨导致洪水和泥石流；7月13日，韩国南部地区的日降雨量超过一个月的降水量。 

　　如此大范围的强降雨和洪涝让人们不禁回想起1998年的中国长江流域特大洪水。目前来看，今夏长江流域的降雨和洪涝堪比1998年。二十多年过去了，无论是对极端降水事件的科学认识，还是对各种尺度天气系统的预报技巧都有了显著提高。 

　　为了讨论、总结这些进展在今夏暴雨的预报和防灾减灾工作中的作用及对未来工作的启示，大气所主办英文期刊Advances in Atmospheric Sciences（AAS）主编邀请AAS的中、日、英、美编委组织“2020之夏：亚洲的强降雨—机制、可预报性与影响”专刊，期待相关领域专家学者投稿！

　　Summer 2020: record rainfall in Asia – mechanisms, predictability and impacts   

　　Call for papers   

　　First Circular 

　　Editors: 

　　Robin Clark, Met Office, Exeter, UK 

　　Xiquan Dong, University of Arizona, USA 

　　Jianhua Sun, Institute of Atmospheric Physics, Chinese Academy of Sciences 

　　Tetsuya Takemi, Kyoto University, Kyoto, Japan 

　　Huiling Yuan, Nanjing University, China  

　　Rationale: 

　　This year’s wet season rainfall throughout vast areas of Asia has been extraordinary. 　  

　　After an exceptionally wet May in North East India and Bangladesh (which had double its usual May rainfall), excessive rainfall hit at least 10 provinces in central and southern China in June and July, causing extensive flooding impacts in many rural and city locations. Long standing rainfall, lake and river level records were broken in central and southern China. Flooding and landslides have also affected Japan with parts of Kumamoto province even recording 1000mm in just 3 days in early July. Southern regions of South Korea also received a month’s worth of rainfall in a single day on July 13th. 　　  

　　Current indications suggest that interactions between the simultaneous development of quasi-stationary precipitation systems along a very broad, extremely slow-moving front have played a role. 　　  

　　The amount and impacts of this summer’s rainfall are promising to exceed those of summer 1998, a major flood year in recent history. Since 1998 however, scientific understanding of such events and predictability on all timescales have improved substantially. This special issue, therefore, is a superb opportunity to show how these advances can be applied to events which have affected millions of people in the regions impacted. 　  

　　Scope: 　  

　　Submissions, covering all aspects of the events of this summer are invited. 　  

　　In particular, contributions regarding the dynamic mechanisms causing the Meiyu/Baiu rainfall, its predictability and the uncertainties of short-term climate predictions are of special interest. This includes predictability on short, medium and seasonal range timescales. 　  

　　Furthermore, given that these types of events already occur in East Asia, and that climate change could enhance such events, we also encourage submissions about how the events of this summer could change in a future, warming world, to inform early plans for adaptation and mitigation of future occurrences of this type of summer. 　  

　　Important dates: 　  

　　Manuscript submission open: August 1, 2020   

　　Manuscript submission deadline: March 1, 2021.   

　　Papers will be published online upon acceptance
