An unusual aspect of this spell is just how good the visibility has remained. Normally with a prolonged period of easterlies the air is very hazy by now, but it still seems very 'clean'.

Does anyone have a backward trajectory of the air over the last couple of days? Yesterday the visibility was excellent.

Penzance Bit more breeze today.

Graham. You may get some idea of the trajectories from this site, though
London will be your nearest location.

I'm a bit late on picking up on this but you can have a lot of fun with
trajectory analysis here

http://ready.arl.noaa.gov/hypub-bin/...untype=archive


It's not all that intuitive to begin with but with a bit of prctice
it's a very useful tool.

Thanks Norman,

I had a quick play without reading any guidance and got a 'program has crashed' message. I'll resort to reading the instructions & go again!

I've finally got around to reading the book - half way through.
