The midwinter suppression of the North Pacific storm track associated with the East Asian trough and Pacific blocking

Resolving the conundrum of the mid-winter suppression in the North Pacific

“…Being dry, these simulations rule out a decisive role of diabatic effects; and being zonally symmetric, wave energy cannot be advected away more rapidly from the most baroclinic sector of the storm track. Further, being zonally symmetric, these simulations rule out variations in upstream seeding of the North Pacific storm track by eddies from the Asian continent as an explanation, a potential mechanism that received considerable attention for a while [8,9,[13][14][15][16][17].…”
