Do we ever really get a Siberian blast (other than in Daily Excess
headlines)? I know it's used as a description of cold windy
weather, but some people talk as if we actually get Siberian air
over us, rather than heavily modified continental air, which could
have come from anywhere. After all, Siberia is 2500 miles plus
from us!

I think that Gordon Manley said in "Climate and the British Scene" that
it's exceedingly rare for us to get air that started east of the Urals.
