Can anyone with access to the original literature shed light on the
period(s) over which Alexander Buchan based his analysis?

Gordon Manley, in "Climate and the British Scene", mentions a book by EL
Hawke called "Buchan's Days", published in 1937 by Lovat Dickson. If you
can trace a copy, it would probably answer your question.
