Cold Waves in Europe and Asia
qThe most extreme area of
all is northern Asia (Siberia).
qWhere the formation of
cold surface air is enhanced by (1) the large distance to the nearest unfrozen ocean, isolating
the area from warmth and
moisture, and (2) the presence of mountains to the east and south, serving as barriers to trap and
further isolate the cold surface
air once it has formed.
