Cloudprince conceived of this back on the autumnal equinox, and it's still a great idea. I will only suggest that the pix can be of autumns past if you like, so that members south of the equator can post photos, too. I will start with this:

Taken last week, West Midlands.

Oh go on then. Getting the gliders out on a calm misty autumn morning at Deeside Gliding club.



And an autumnal Ballater and Tarland Bowl from above.




OK a lack of clouds in this pic but Balmoral is looking nice and autumnal too. But looking the other way Braemar and the Linn of Dee look lovely. The A93 snaking off to the left towards Glen Shee.




And finally, to show it's no longer summer, I've already seen snow this Autumn. 5th October on Cairngorm at cloudbase:




This is what happens when a storm cloud condenses on an object:

It is amazing to know that trees in England still have many green leaves. Leaves are gone from the trees in the northern United States, at latitudes much more southerly than England. Thanks for the geography lesson, C.M. and Mike.

Hehe Andrew don't let the Scottish hear you calling their part of the UK England. You'd have a war on your hands. All my pics were in Scotland. Down south in London (, England) autumn is slightly earlier despite the warmer climate, because (as the weather men explained recently) it has been rather dry here putting the trees under strain, so they have switched off early to have a rest. Certainly the conkers were early this year. Scotland is a bit later I suppose because a later start and because it is still comfortably warm but it's not been too dry.

The UK is always warmer than other places at this lattitude, because the gulf stream channels warm water from the caribbean to the Northeast Atlantic in a huge conveyer belt. This is why snow is so rare here in the winter these days.

The result is a huge battle ground. We have atleast 4 different airmasses jockeying for position. The warm moist air from the SW (gulf stream), the warm dry air from mainland Europe (which becomes cold dry air in the winter), cold air from Scandinavia (dry) and the more direct north (moist). So no wonder we British folk get such a wide variety of weather conditions and glorious clouds! And why Britain has a reputation for unpredictable weather!

Currently our air has come from West Africa, which is very warm and moist. The result is what we call an 'Indian Summer'. Max temps down south are almost 20C. This time last year, in contrast, it was snowing! Welcome to the UK...
