Plain Language Summary: In July and August (JA) 2018, the monsoon trough in the western North Pacific (WNP) was unusually strong, the anticyclonic ridge was anomalously northward-shifted, and enhanced and northward-shifted tropical cyclone activity was observed. This study proposed that the local effect of both the tropical and extratropical WNP SST anomaly as the major driver and the remote effect of the North Atlantic SST anomaly as a minor contributor jointly induced the anomalous circulation and climate extremes in the WNP during JA 2018.
