The effect of the recent explosive cyclogenesis on Runswick Bay.

Very little, really. The winds were predominantly South Westerly, Runswick Bay faces due North and the cliffs create a wind shadow so the Bay itself was pretty calm.

The effect off Sandsend (Whitby piers in the background) was more pronounced, with the wind tearing the crests off waves:

Explosive cyclogenesis happens when a low pressure area deepens by 24 millibars over a 24 hour period, making the circulating winds more powerful. Meteorologists' shorthand for such a system is a 'bomb', something gleefully seized upon by the media last week. We need some Northerly gales to send in a couple of days of large waves, tear up the seabed, strip away sand and bring down some cliff falls. That's when things get interesting around here.

Well I regard that as a compliment from the photographic master.
