Randomized trial investigates ENSO's effect on East Asian winter monsoon, highlighting PDO phase implications.
Key Points
This research aims to explore how the Pacific Decadal Oscillation modulates the influence of the El Niño-Southern Oscillation on the East Asian winter monsoon.
Analysis of interdecadal modulation of PDO and its relationship with ENSO and EAWM.
Investigated temperature changes over East Asia during different phases of the PDO.
Examined teleconnections and midlatitude responses associated with ENSO.
No robust relationship was observed between ENSO and EAWM in the high phase of PDO.
Significant low-level temperature changes occurred in East Asia during the low phase of PDO due to ENSO effects.
The findings emphasize the importance of PDO phase in predicting wintertime climate in East Asia.
