Synoptic climatology associated with extreme snowfall events in Sapporo city of northern Japan
Abstract Synoptic‐scale atmospheric circulations are crucial for extreme snowfall events. On the basis of topmost 100 snowfall intensity days in Sapporo, Hokkaido, Japan over winter seasons from 1992 to 2011, this study uses principal component analysis and K‐means clustering to characterize synopti...
