本研究旨在探讨厄尔尼诺-南方涛动(ENSO)对中国南部冬季风与夏季风之间可能联系的影响。在北半球冬季，东亚冬季风(EAWM)的强弱北风异常席卷大陆至沿海地区，可能有利于ENSO事件的发生。在北方夏季，中国南部降水偏少(偏多)，极端气温偏多(偏少)，可能处于暖(冷)ENSO事件的成熟期。研究还发现，在接下来的一年里，更频繁的寒潮之后可能会出现更少的极端气温。这可能与西太平洋副热带高压在经历强(弱)EAWM年后，通过ENSO事件的改变而北(南)移，可能导致中国夏季风早(晚)爆发，并导致来年夏季风强(弱)。
The objective of this research is to explore the impacts of El Niño-Southern Oscillation (ENSO) on a possible connection between winter monsoon and summer monsoon over South China. In boreal winter, the strong or weak northerly anomalies due to the East Asian winter monsoon (EAWM), sweep across the continent to the costal regions, which might be favorable for the occurrence of an ENSO event. In boreal summer, South China tends to experience less (more) rainfall and more (less) temperature extremes which might be in the mature phase of a warm (cold) ENSO event. It is also found that more frequent cold surges might be followed by less temperature extremes in the coming year. The possible connection might be that the western Pacific subtropical high after a strong (weak) EAWM year would move northward (southward) through the modification of a ENSO event; this northward (southward) western Pacific subtropical high might result in earlier (later) south China summer monsoon onset and lead to a strong (weak) summer monsoon in the coming year.
