I wonder if some one has a UKMO North Atlantic surface analysis for 12
UTC on 3 Feb 1991, or indeed any surface analyses for 02-03 Feb 1991.
This relates to the exceptional extratropical cyclone known as 'The
Greenhouse Low' which produced extreme winds over Iceland.

Sorry I cannot answer this but do have a question.
Did this low have any affect on the delevopment of the significant
cold and snowy spell that month?
Well the flow over Europe was blocked and the Greenhouse Low was one
of a number that developed at low latitudes and ran polewards on the
western flank of the high. Modern theories of blocking emphasise the
importance of transport (of Isentropic Potential Vorticity) to high
latitudes, reinforcing blocking, so they may well be related in some
sense.
