Plain Language Summary: An unprecedented cold wave swept through most parts of East Asia in January 2016, leading to record–breaking low temperatures and widespread snowfall in several regions. Our analysis indicated that this East Asian cold wave was triggered by a low-frequency downstream development process in the Northern Hemisphere from late 2015 to early 2016.
