A Pacific-East Asian teleconnection hypothesis is put forth to explain how the El Niño affects the ” upstream” climate in East Asia. The key circulation system that conveys the impact of El Niño to East Asia is the anomalous anticyclone in the western North Pacific (WNP). This anomalous anticyclone is maintained through a positive thermodynamic air-sea feedback in the WNP. The wind fluctuations associated with the monsoon anomaly may further remotely impact the El Niño evolution through exciting consecutive equatorial oceanic Kelvin waves. The rainfall variability over the Meiyu region exhibits a strong biennial signal in the correlation with the equatorial eastern Pacific and Indian Ocean SST. This interannual monsoon-ENSO relationship is subject to an interdecadal variation. For 1951-77 an El Niño-like condition precedes both enhanced Meiyu and southeast China monsoon seasons, whereas for 1978-96 an El Niño warming precedes an enhanced Meiyu but a deficient rainfall season in southeast China. It is hypothesized that this results from the interdecadal change of the basic state. The possible impacts of East Asian winter monsoon on the onset of El Niño is also reviewed and discussed. %@ 978-981-238-769-1
