Unfortunately in our part of mid-Devon we are surrounded by hills, and for most of the year are deprived of watching the ‘true’ sunset or sunrise, but in Winter we are a little less restricted both towards the southeast and southwest, as it was this evening. It looks like we might be in for an early frost if the cloud doesn’t roll in later during the night.
I’ve mentioned in several of the postings I’ve made this morning about how yellowish the clouds have been ever since dawn here in Devon. Well my neighbour has just knocked at the door to say just how reddish the sun was as he drove back from Cullompton just now. So I broke off from blogging and managed to capture a couple of pictures of it as it was just starting to poke through the thinning sheet of CS. I did pooh pooh the notion that it was Saharan dust that was causing it, but now I’m not so sure. I apparently missed the sun when it was at its […]
Medium layer cloud is still much in evidence across the southwest this morning, possibly the remnants of yesterdays weakening cold front that marks the boundary between air with dew points of 9°C in Devon to 17°C in the north of France (fig 1). There is some rather fine altocumulus (fig 2), and despite the surface flow being east of north, I reckon the flow at 17,000 feet (LCBR at Exeter airport at 09 UTC) is from around 248° at 27 knots, if my rather crude estimates are anything to go by.
[foogallery id=”7685″] Funny, it already seems a long time ago now…
At first I thought that this was low AC when I first saw it, which shows you what a poor observer of cloud I was in my day, but the LCBR at Exeter airport reckons the base is 5,000 feet, and I’m not going to argue with that. Feel free to tag on some extra supplementary varieties to the description such as undulatus, perlucidus (gaps between), or stratiformis.
I noticed this very interesting photograph of a solar halo in cirrostratus with a condensation trail running through it on the Astronomy Picture of the Day website.
Suddenly people are reading that a new type of cloud asperitas has arrived on the scene, I even wrote a bit about it this week. Some people have now also started to think (if this article in the Guardian is anything to go by) that global warming has now produced many more exotic cloud types that have never been classified. I suppose as a cloud lover this should be good news to me, it’s making people more aware of clouds, in fact it’s popularising clouds, but to an old curmudgeon like me that’s not good news. It seems that popularising things that were once ‘nerdy’ or ‘geeky’ things to do just […]
