How Autumnal Snow Cover in Siberia Really Relates to Cold Winters (Weather Explained #4)
Eurasian snow cover, tropical convection, and stratospheric dynamics form an interlinked system shaping midlatitude winters. This article examines recent research—including Cohen et al. (2021) and Gastineau et al. (2017)—to show when early snow growth strengthens the polar vortex connection and when it fails to. Continue reading
