摘要：
In this research, characteristics of summer runoff variations during monsoon season in the Yangtze River basin and their connections with Asian summer monsoons were detected by using continuous wavelet transform and wavelet coherence analysis methods. The following results were obtained: (i) The periodic character of summer runoff along the mainstream of the Yangtze River basin has distinct differences upstream and downstream of Yichang station. (ii) Summer runoff of the source and upper regions of the Yangtze River basin is mainly influenced by the South Asian summer monsoons. Summer runoff of the midstream and downstream regions of the Yangtze River basin are controlled by the East Asian summer monsoons. (iii) An in-phase relationship between summer runoff and South Asian summer monsoon intensity indices is detected in the source region of the Yangtze River basin, and an anti-phase relationship between summer runoff and East Asian summer monsoon intensity indices dominates in the midstream and downstream regions of the Yangtze River basin.
