Just popping on as I found an interesting series of photos in between the subject I finished on last time and that I was going start on next time…my trip to Germany a while back. Now, I’ll say in the very early stages, this may or may not interest you so I won’t take offence if I don’t get any feedback! However, I find this kind of thing very interesting and, in a way, beautiful when it comes to the shapes in the clouds. If it is one thing I’d encourage you all to do, it is to look up once in a while, clouds aren’t all flat and grey.
One afternoon, just wandering around the house minding my own business I expect, the day got a little heavy cloud-wise and the first clue that something was swirling around appeared…
Now, without being able to point in directions and add annotations (I haven’t worked that out yet) you can see that a shelf of cloud is developing and is moving in from the upper part of the sky from right to left. In the distance, you can see the yellow colour displayed when there is rain in the air too and even a bit of virga. The thing is, when you looked to the left, the same was happening….
In this image, you can see in the upper part and the lower part there is some compact and elongated mammatus and some distinct curves in the cloud where more is developing. A sure sign that rain is coming! However, seeing one big lump is coming one way and one the other, this is where is got interesting as they met in the middle and created this kind of melee of tumbling clouds at low-level…
This continued on for quite a while and things got very dark and distinct lines of where the air is pulled in and pushed out became apparent in the form of asperatus-like curves and shapes…
Sadly, all things come to an end and the lovely show came to messy finish where everything was jumbled up all over. I was hoping for a rain shower, a clap of thunder or maybe I read things entirely wrong!
Mind you, not being one to give up easily when it comes to clouds (I often wonder what the residents of the houses backing on to the fields where I take my sunset pictures think of me) I saw that following this was a very distinctly shaped cloud which I have looked around for on the webby net. It seems that it ticks all the boxes for part of a flanking line for a storm cloud, so I think I was right! It was a storm close by but not over us..
In the words or Mr Wikipedia “a flanking line is an area of small clouds that mark an area of widespread updrafts in front of strong thunderstorms. These flanking lines generally occur in the vicinity of supercells or large multicell thunderstorms. The bases of the clouds making the flanking line are merged (like in the picture). The forefront area usually has no rain” (this accounts for the fact there was no rain the whole time.
“These feeder clouds will merge with the main cumulonimbus and will regenerate the storm.” That I can’t vouch for but “the feeder clouds are located at the west or southwest of the main cloud” I can vouch for as the large town that pretty much always has these big rain storms is located in that direction.
Just call me John Kettley.
Well, this concludes an overly scientific and speculative diagnosis of weather in my area of Wales. Next time, we embark upon a road trip to Germany! Thanks for dropping by and sticking with me in this post.
Well, hello from Storm Angus ravaged Wales!
Kind of storm ravaged. Okay…not at all, just the tail end. We didn’t get this all half as bad as the south of England, if you wish to, you can read about the main bits in the Daily Telegraph.
Cue the normal film (courtesy of YouTube on this occasion) on the evening news of people who should know an awful lot better canoeing in the street, standing perilously close to waves crashing onto beaches, generally being a teeny bit dull or driving into water that is far too deep.
Honestly, if I knew that Newhaven and Brighton and similar areas were going to get this much coverage in the years after I moved to Wales, I wouldn’t have bothered coming! Only kidding. Still, at least I stayed relatively dry. The wind was perishing cold though, that was what bothered me the most as I don’t have an awful lot of meat on me. This is due to get less after Christmas too as I will be embarking on a proper 12 week training regime to do a further sportive bike ride of 100 km (60 miles) in aid of charity. I was looking at the handy downloadable training timetable and I am struggling to think of routes that fulfil the length of time or distance needed and also go in a loop to assist me in not transporting the bike around the county in a car that is too small for it. I’m sure it’ll be fine.
However, let us not be bothered by my good deeds. You read this for my wit and pictures don’t you? I like to think so, but I could be having a one-way conversation with the vast internet. So let us begin.
Iridescence. Difficult to spell, even more difficult to spot. More difficult to photograph than both of those things. I think I have posted images on here with some “mother of pearl” effects in some winter clouds but these are not to be confused with the proper nacreous or polar stratospheric clouds.
In this instance, you have to look very carefully at the tips of the dead clematis flowerhead I took a picture of a while back…
I never noticed the fact there was some iridescence in this image when I took it to be honest but looking at Mr Wikipedia…thanks be to Wikipedia…it says that the effect is generally created by microstructures that interfere with light, which figures as these flowers are very intricate and the flash fired in this image.
On to a more familiar subject, the sky, but a more unusual effect in the clouds than usual. You may remember a while back that I pointed out some oh-so-catchy Kelvin-Helmholtz instability in clouds at sunset that caused what look like cresting waves? In a nutshell, it’s the interaction of two fluids of varying density such as the wind creating a wave on water (yes, air can indeed be construed as a fluid in science). It seems that the effect can go full circle (pun intended) and create what essentially looks like a corkscrew.
Pretty cool, huh? I have only seen this the once and I can only find a few images on the internet that are similar, so you never know, I may have stumbled on a new cloud type! I will name it “the screw-mulus”. Or I could be over-thinking things….yes, the latter.
Now, moving away from science but to return to it in a little while, some sunset pictures I took just because and in the order of this post heading towards the end of the day in subject matter. Not that many sunset images at all this year, seems we have way too much low cloud now, so there will be fewer and fewer of these images of feathery loveliness…
This next one is an unusual one as there are quite a few “straight” lines in the cloud. I say straight with a little bit of a nudge as they aren’t ruler straight, but in nature, you very rarely find anything too straight, so when you see it, it’s usually due to interaction with something unexpected…in this instance, I suspect the contrail on the right at a similar angle has something to do with it.
Back to science! Rays. In particular, crepuscular rays. I have posted many images on here of these rays but now I present to you a rarer image of….anti-crepuscular rays. It is pretty much the same thing but you see these opposite the sun, not around it, behind a cloud or such like. The rays are caused by the interaction of the light with an object out of your line of sight due to the curvature of the Earth, so as the sun dipped just below the horizon here, a little cloud got in the way, casting this shadow…
Apologies for the dark image, I had to fiddle the contrast to enhance the rays somewhat. However, talking of dark brings me nicely to my last image for this post, a nightscape. I don’t often do these, as it’s not an area I have a great deal of skill in, but I try. I took this of the refinery and fuel storage areas around Pembroke (on the left) and Milford Haven (on the right) from Pembroke Dock.
I even managed to catch a little starlight in the image which was not my intention, but it adds a little depth to the inky black bits. I might try this further in the future, but I find them a little boring being so dark and having a not so well suited camera for this kind of stuff. We shall see.
Well, there you have it for another post. Before I go, just a couple of things…I need one more follower to reach 50 so if you have a friend or relative who can stand my infrequent babble, tell them to pop to my site on a PC and click the “Follow Me” link at the bottom right. Thanks!
Also, I have changed a few bits on the site such as the background banner and post text. Hard to read, too small, too large? Constructive criticism is very much welcomed!
Cheers in advance and see you soon.
Thanks for dropping by on the email you get sent to a spend a couple of minutes hearing me drone on.
Well, it’s been a busy and interesting couple of months for me. To be honest, the less said the better, but in the middle of it all was a three week holiday, so I will use that as my very valid excuse for not posting. I went to the south-western tip of Ireland again…some of you may remember I posted a video of the time I went whale watching in the same area. No? Shame on you! If you wish to have a look, either search my name on YouTube or go to Humpback Whale Awesomeness in my previous posts.
For those who wish to go to the area, I can highly recommend it and will be posting pictures of that area in the near future, as I now have time on my hands to do more regular posts. The first time was gorgeous weather, this time it was less so, but still very enjoyable and there are some lovely vistas to post.
However, I stray from the post I am doing. Now that Autumn is upon us, I though I would keep a few of the Summer pictures coming for a short time to keep us all from seeing too much brown and wet images by looking out the window! In the first instance, just along the way, it pays to look out of the window for those photogenic weather shots as along popped a little back-lit shower…
I’m quite proud of this. I would put it in the folder marked “might consider getting printed when I have a place to nail it to in the future”. Catchy, huh? Alas, the folder is quite full, so I will need to purchase a stately home! I thought I’d add a slightly after picture too, to point out the lovely glaciation (virga) effect as the little cell collapsed…
You remember me talking about glaciation? The jellyfish clouds are the most common form of this but in this case, I think what happened is that the top of the cloud suddenly outgrew what could be supported and became a little icy, then just fell down slowly, creating the shower you see above.
Next, a lovely sunny picture to inject a little landscape love! This is one of my favourite views on the Preseli Hills. I know most people climb the road or hike the hills and look south, but I much prefer the view to the north…well, the north-east. Essentially, in the distance from this view-point, you can see all the way to the end of the National Park and you are looking along the line of hills towards Crymch. This side is noticeably more rugged than the south, which is why I like it.
Also, don’t forget, there is a lot of history here and that adds to the attraction. Pollen analysis suggests that the hills were once forested but the forests had been cleared by the late Bronze age; the hills are dotted with super-aged remains, including evidence of very early settlement…you know, grunting and flint type stuff. It has been mooted that bluestone from the hills is similar or the same as that used to build the inner circle of Stonehenge. Lots of people with beards and letters after their names have argued but seem to have settled on the fact that the stones have come from multiple sources on the northern parts of the hills…the exact way the photo looks.
Further south now, a few colourful pictures from the southern extent of the Park, thankfully not showing the overrated beaches and towns, but the much ignored Blackpool Mill. Again, I have mentioned this before but I like this picture showing the old mill tucked away in the forest…
Moving in a little closer here, a tiny member of the thistle family in full flower, covered in pollen and waiting for a bee come along and do a swap and continue the line. No proper thistles here and I’m afraid I can’t put my finger on the exact name of this one.
From bees to wasps. Now, no hatred for the poor wasp. I know they buzz your food and beer on the 3 or 4 days you are able to eat “al fresco” in the UK and that is a pain, but they’re only trying to eat. Anyway, I’m going to big these little blighters up. I mean, check this bad boy out, that’s quite an undertaking for a tiny insect….
But wasps have a useful purpose. Wasps are predators who hunt and eat almost every pest that harms crops including grasshoppers, aphids and flies. Also, don’t forget, the nest is made of what is basically a wasp super wallpaper…they chew bark or wood up, mix it with saliva and spit it out in a thin rough paper to a high degree of accuracy which is brilliantly efficient at both retaining heat at night or to grow larvae and to cool residents on a hot day. So, even if you hate them, give a little respectful fist bump to a wasp, rather than smacking it with a copy of the Daily Mail….additionally if you do that, it just attracts more as a dead wasp releases pheromones attracting the masses!
In this case, I returned a few days later to see the nest destroyed…I hope the person who did this got a most uncomfortable sting.
To finish, as is usually my favourite thing, a dusk scene. Again, not very far away but hopefully attractive in the way there are lights, darks and silhouettes in the same image…
Well, thanks again for popping by. No promises on the date of the next blog which will be moving on to a trip to Germany, but I am hoping for sooner rather than later and I may even consider a slight revamp of the set up if I have the option. Groundbreaking stuff! However, I might need to speak with the PC first as it’s beginning to creak a little. Should be fine though. Famous last words…..
Ta-ra for now!!
