Plain Language Summary: The northward shift of the western North Pacific Subtropical High (WNPSH) in July 2018 broke the historical record since 1958. The present work attributes the extreme WNPSH anomaly to the strongest positive tri-pole pattern of sea surface temperature anomaly (SSTA) in the North Atlantic. This SSTA could induce an eastward propagating wave-train over the Eurasian Continent and enhance the atmospheric diabatic heating over the eastern Tibetan Plateau to cause the extreme northward shift of the WNPSH, finally leading to the extreme heat waves and casualties across Northeast Asia (NEA), especially over the southern Japan.
