石笋记录年际、年代际极端天气/气候事件研究进展

近年来随着极端天气/气候事件的频发，应对极端天气/气候事件的要求极其紧迫。目前气象资料对极端天气/气候事件的研究相对较短，由此作者提出利用石笋记录重建历史年际、年代际极端天气/气候事件的构想。通过对目前已有的石笋极端天气/气候事件研究实例分析总结，认为洞穴石笋沉积速率相对较快，石笋中标志性结构构造特征的存在，有利于石笋记录到极端天气/气候事件。同时就目前的研究现状，作者提出建立准确年代标尺、选择生长速率相对较快和存在标志性结构构造特征、能记录到极端气候的石笋，以及提高采样分辨率和与其他记录相互验证等作为石笋极端气候研究的工作要求，同时就文石笋研究极端天气/气候事件提出文石笋可能更加容易记录到极端天气/气候事件的个人新认识。 

Research progress on the interannual-interdecadal extreme weather event recorded by stalagmites

Along with the frequent occurrence of extreme weather events in the recent years, it is very urgent to deal with the events. The meteorological records are only several tens to hundred years, it is hard for us to research the extreme weather events clearly, so the authors point out using the stalagmite to reconstruct interannual-interdecadal extreme weather events. We hope other researchers can pay attention to it. Examples of reconstructing the extreme weather events with stalagmites are analyzed and summarized in the paper, which proving that it is in favor of recording the extreme weather events for stalagmite because of the faster growth of cave stalagmite and the existence of symbolic structure and texture in the stalagmite. According to the progress of extreme weather event research, the authors propose to construct precise age ruler, search for stalagmite with relatively fast growth rate and special structure, improve the sampling resolution, use other records to confirm the extreme weather events which will helpful for confirming the extreme events recorded by stalagmites. And the authors also point out aragonite stalagmites may be good materials for extreme weather event record.
