After a fairly sunny afternoon yesterday ( http://www.sennen-cove.com/26jun14.htm ) with a Max of 20.4C, more heavy showers overnight dropped 10.4mm, some really large drops. Minimum a cooler 10.9C



Currently sunny spells, and a fresher feel than yesterday. F3-4 SW and temperature currently (10:45) near 17.5C. Very good visibility.



The swell is building, it just needs the wind to drop a bit, which it is forecast to do, and conditions could be quite good tomorrow. http://magicseaweed.com/Sennen-Surf-Report/4/

I think showers and /or drizzle are a brief introduction to a new spell especially when we are enjoying a positive phase of the Arctic/NAO.

Do you have any idea what the Richardson Number would be for such a set up? Ri1 or Ri1.

I am have one hell of a job trying to find out what all that Brownian motion dimensionless numbers is all about. I am trying to determin what overall effect such a scale of nonentity the pressure gradient of the MetOffice&Climategate chart shows for the North Atlantic at the moment:
