Going to get some at home for sure with that polar low running down the

It's that sort of feature that can give a very strong wind here, often a good deal more than the a glance at the isobars suggests, due to the Lands' End peninsula squeezing the flow and also a funnelling effect down the NNW-SSE orientated valleys (a feature resulting from a tilting of the approx 300' raised beach) For those that know the area Chapel Carn Brea was an island, now surrounded by the 30' plateau. (Well 250' towards the south 350' along the north coast.)

Sorry, drifting back into my geomorphology days.

Do you mean a 300' plateau? When would that have been formed, the Eemian?
