After the wind drops

That's interesting.

I've taken a look at tomorrow's chart. East anglia has a line of strong thermals at the coast. I guess this must be the cooler sea air being forced aloft as it meets the warm land mass?

The times given are 1230 (midday). Is there any indication of how the thermals drop during the day - specifically the last 3 hours?

Ah - Just noticed the time bar on the right. Very useful. All goes a nice shade of blue during the last 3 hours.

you v'e got the right idea, but it's the other way around, it it the the warmer land air that gets pushed up as the colder sea air wedges under it
