Re: Orange Sun

... Similar experience to others here (West Moors/East Dorset): whilst out shopping around 0930-1030Z, sky becoming increasingly dark/threatening (Beaufort = "u" perhaps?) and by the time we got home 1045Z, my wife was getting seriously worried that 'something' awful was going to happen. N...

Re: Are summers becoming wetter?

That seems to tie in with this graphic on the Met Office site .... England only .... also (not shown) it is reflected in the EWP series since at least 1970:

Re: Snow pellets

... well, I'll pitch in to be shot down(!): I always regard such as a day of /hail/ - *unless* the shower is genuinely accompanied (as in the published definition) by flakes of snow - in which case I record both a day with hail and snow. All the coding for things like NCMs, Beauforts, SYNOPs (old an...

Re: Contrail lobes

... thanks for posting that image: every time I see these 'lobes' I'm captivated by the apparent complexity of exactly how they form. The article you mention gives a creditable mechanism - but I wonder how many looking upwards on a fine day realise just how 'dynamic' is the atmosphere around these f...

Re: Asperatus?

... I wouldn't be calling that cloud (as in original post) as anything other than Sc stratiformis opacus undulatus. Not even mammatus (from that shot - but photos can be notoriously deceptive). Asperatus/Asperatis has a much more "tortured"/intorted look about it . . . see examples here:- ...
