| 摘 要： | 青藏高原积雪作为亚洲夏季降水异常的一个预测因子已有很长历史。统计分析表明，青藏高原冬春积雪与印度夏季降水反相关，与我国长江中下游夏季降水多为正相关，不同作者对此现象给出了一些可能的解释，如地表反照率效应和积雪一水文效应。但积雪的这种跨季节滞后影响的具体物理过程仍有争议。另一方面，青藏高原冬春积雪资料存在不确定性，这对相关物理机制的理解造成了很大困难。通过回顾和梳理前人在该领域的研究成果，提出了高原积雪影响亚洲季风的未来研究方向。

| Abstract: | The Tibetan Plateau（TP） snow depth（SD） has been considered as a predictor to predict Asian summer precipitation anomaly for a long history. Statistical analysis reveals that winter and spring SD over the TP presents a negative correlation with Indian summer precipitation, while a positive correla- tion can be detected with the summer precipitation in the middle and lower reaches of Yangtze River. Some possible mechanism has been provided to explain these relationships, such as surface albedo effect and snow-hydrological effect. Nevertheless, the involved physical processes regarding the delayed effect of winter and spring SD over the TP upon the Asian summer precipitation is still controversy, which is di- rectly induced by absence of enough and high quality data over the TP. This paper presents a review of existing studies on this topic and proposes some potential key points for future research. |
