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!!
I return. Been a bit busy of late and with the weather getting better by the day, they has been quite a lot of riding of my new bike to be done. Also, when I had it serviced recently I opted to fit gel inner-tubes to protect against punctures, so I am now more confident riding the paths around here that seem to be strewn with thorns for some reason.
Also, my work colleagues have decided that being single is a source of lunch hour amusement for them and have put me on a site called Plenty of Fish…probably to take the mickey even further, but it’s quite time-consuming! I was also persuaded to attend a singles night locally the other day; little did I know that I would be the only person there. No, not the only man, the only person. I even got let down by people who promised to come with me! The barmaid was very apologetic, but it was super embarrassing…
Anyway, what a difference an hour makes in South West Wales weather? When I got up the wind was blowing and the rain was horizontal but now, I’m squinting against the sun as I type! Mind you, there has been a lot more of interest in “space weather” of late as you may have seen on the news lately? If not, there was a “supermoon” (which saw some amazingly low tides around the beaches near here), the partial eclipse and a sighting of the Northern Lights over Pembrokeshire. Should you want to see the local cover, please refer to the local paper…
Read about the eclipse over Pembrokeshire here
See some pretty awesome (although not as you see them in Norway, unfortunately) Aurora pictures here
Anyway, I shall start popping my own pictures on now! As I said, this is a bit of a random collection of mainly weather, as it appears that my travels were somewhat curtailed and these were more local wanderings. Firstly, a spider that caught my eye in the garden, wrapping up his next big meal it appears..
That is a pretty funky spider tattoo down his back, isn’t it?! I fully admit that I am no fan of spiders, but will concede that they are amazing little creatures. I am quite thankful that I live in a country that just has small ones though, not like the tropics. Eeek!
Moving on to the skies, as I quite often do, a nice dusk that I took a few pictures of. I have included these as I noticed on review of the images that there was a little aberration in the latter picture…not sure whether I noticed this at the time though…
In the latter image below, just above and to the left of the trees, you will notice a line of Kelvin Helmholtz instability. Now, I don’t know whether this is some optical illusion or something as the earlier pictures shows some “waves” in the high cloud. I can’t say for sure, but I’d like to think I caught the creation of the waves over time 🙂
Next, a common occurrence over Pembrokeshire, some mild asperatus. This is the only place I have ever seen the regular appearance of this cloud, that is similar in age to me. In that, I mean that it wasn’t really officially recognised as a type of cloud until 30 or so years ago; I’m sure it has been around for donkeys years. In the textbooks and such, this is a precursor to rain or is on the rear edge of a front that was just carrying rain (this I can testify to). So, if you see clouds like this, get a coat….
As the sky got a bit dimmer, there was a nice watery orange sunset so I snapped a quick image of that with a little of the asperatus in…
A few days later, things had turned a bit squally again. This again seems to be a theme here, there are times where we have weeks of squally heavy showers and because of the position of the house and the hills in the distance, we get a pretty good grandstand view. In the first instance there was this little cell struggling to make itself into an anvil shape over the estuary to our north, bless it…
Alas, wind blew this little cell apart and it died away to be replaced by three of four layers of “scud” which were whipping along in the wind at quite amazing speeds. I took a picture of these as they passed, as the colours and contrasts of the different levels were pretty cool, I thought…
For every cell that falls apart there are a few that succeed in dropping their rain. This one and the following picture are from a day where things were a little less “lumpy” so they are much more streamlined and pleasing to the eye, even though in looking at them you would have got wet! From this angle, you can see what I mean in me getting a good view as the weather moves from left to right (from the Irish Sea inland)…
And to finish, a rainbow! Everyone loves a rainbow. No particular structure to this one as this was a fleeting one that passed by in the clouds as the rain flew around in the air. Again, this is something which happens quite a lot in the Spring around here, very pretty…
Well, there we have it, I hope that the fact that the sun is (trying to come) out and the flowers are blooming has cheered you up and these picture may have raised a grin too. Don’t forget the clocks go forward this weekend too!
Next week, I see that I was out and about when there was fantastic display of cirrus “mares tails”, basically windblown cirrus clouds very high up in the atmosphere that also seem to show themselves in advance of heavy weather which I also manage to capture, so I shall be posting those images. I have others from my wanders that week too so if you are good, I might post some more moving water…
Well, that’s the lot for this post, cheers for dropping in and taking a peek, see you soon. I will also update you on any decent single life news in the next entry 🙂
Apologies for the break here, the main reason has been that the weather has been pretty good of late so I have usually be out on my bike or wandering getting new material for the blog to file in my archive for later use. The weather has broken after an extended period of good warm sun….typically as the British we moaned as it was too hot about a day into it. Now it’s raining, people are moaning about that. Sigh.
Talking of the photography archive, I have decided that upon a scoot through, I would post some images from the summer storms and rain we had last year as there are a few phenomena to make you aware of.
One day there will be a pub quiz asking about this stuff and you’ll be glad, trust me.
First off, is the first clear occurrence I have seen of a pileus cloud. Usually spotted over mountains and such, this was over a very tall cumulus cloud as the showers sprung up around me. This is also called a “scarf cloud or a “cap cloud” by those who can’t handle a small latin word :p
Mr Wikipedia states that “a pileus found atop a cumulus cloud often foreshadows transformation into a cumulonimbus cloud, as it indicates a strong updraft within the cloud; Pilei clouds indicate that the parent cloud is growing rapidly, has plenty of moisture, and is highly unstable” so I am not making the storms up or over dramatising the weather in these posts. Weather don’t lie!
The next couple of images show virga. Arguably, this is linked to the previous phenomena, as these little cells that collapse and evaporate are trying to be big clouds. Bless their hearts! Basically, it is “an observable shaft of precipitation that evaporates before it hits the ground”.
In connection to my previous comment about the small clouds trying to eat their greens and become big boy clouds, I am right as the science bit says “Virga also has a role in seeding storms whereby small particles from one cloud are blown into neighbouring supersaturated air and act as nucleation particles for the next thunderhead cloud to begin forming”…so I wasn’t making it up. However, sadly on this occasion, none of that happened 😦
This is where my science head runs out. A rainbow in the middle of a cloud?! Crazy stuff! I think in all honesty it is more virga but the sun was very low and at just the right angle to catch the light through the water droplets here. It was very short-lived but pretty.
Once all this had cleared came the edge of a front or “whales mouth”. Don’t ask me why it’s called that but again, the colours were pretty striking so a boring cloud was made a little less boring with a little red on it. However, whilst this was happening, behind me the sky was completely different!
Confused? I was, as this sky and the two or three clouds that made it up were worlds apart from the type I had just been looking at. Remember, as per the usual posts I make on here, this is all in (roughly) the same place on the same day. How things change!
I’m sorry for all the cloud pictures. I should really branch out into other areas, but I looove weather. Alas there are a few more files of this ilk (sky phenomena) to come but then I am going to educate all of you on Belgium as I will be entering the folder containing last years holiday snaps. Don’t sneer, Belgium may be deemed boring and they do put mayonnaise on their chips (which is just weird) but the place is oozing culture and history, you’ll see!
Thanks for dropping in and I appreciate the comments sent to me of late. Please keep them coming. All the best until next time.
I’m back again for another instalment of my usually skyward-gazing photographs from the skies over a quiet area of Pembrokeshire.
Before I forget, as I will probably, I will mention that I am once again entering the WeatherNet weather photography competition this year. I won a prize last year of, I think, £20 which is no kings ransom I admit, but it was nice to get some input. Mind you, I didn’t think the image I sent was particularly deserving but there we are. This year, I have sent some very nice ones and, whilst I’m no storm chasing pro, I think there’s some pretty awesome cloudscapes. I posted some on here a while back actually….in February this year; take a look. I seem to recall I entitled it the best storm cloud ever. How imaginative.
Anyway, back to the current pictures. The first couple I am not too sure about but I think there was some mild disturbance in the clouds called Kelvin-Helmholtz instability. Now, I never did get science at school so let me introduce Mr Wik E. Pedia with his explanation (all credit to the well-known online encyclopedia);
The Kelvin–Helmholtz instability can occur when there is velocity shear in a single continuous fluid, or where there is a velocity difference across the interface between two fluids. An example is wind blowing over water, the instability manifests in waves on the water surface. More generally, clouds, the ocean, Saturn’s bands, Jupiter’s Red Spot and the Sun’s corona show this instability.
Still confused? Me too. Basically, in this instance, it is waves and undulations in the clouds…
This picture may show things a little more clearly. When people say that air should be treated as a liquid, this is where it all makes a bit more sense!
The next phenomena was a little more “normal” per se but quite nice nonetheless. Just a normal squall mixed with some blue sky and cirrus that I regularly watch and take pictures of to begin with, but I noticed that as I was watching, there was a distinct little “cell” (don’t know if I should refer to it as that to be honest, but for the purposes of the blog I will) off to the left of the frame…
Surprisingly, you could actually see this “cell” moving in a spiral manner. It was admittedly happening veeeeeeeeeeery slowly, but you can actually see in this frame that it looked a little like foamy water in a bath plug. Not quite rotating but nearly….
Pretty much bang overhead now and there is a distinct oval/circle formation here with lumpy cloud in the middle which was probably very mild mammatus, having seen this kind of thing on a larger scale on YouTube…
No rain came down from this over us, but I like to think it may have broken somewhere further away. Once it had moved off the light got better and most of the details were lost for the purpose of photography, which was a shame.
Back to my easy wins then! I love a good sunset and I have caught a good few nice ones of late, as well as some arcs and sundogs that will feature shortly. This one is just down the road in Sardis. Truth be told, I was in the wrong place to catch it properly so I had to make do with the less that ideal foreground. Mind you, I don’t think it’s all that bad…
A few days later, the air was still pretty clear and there were hardly any contrails around, so there was a rare full frame cirrus cloud that I took a snap of. Remember, this is how it appeared at the time, none of your digital manipulation here!
Well, I hope that you found this a good distraction for a few minutes…I enjoyed taking the pictures anyway. I will keep you informed regards the competition but the closing date is late September so you will see another few posts before then.
That reminds me, I really must send the remainder of my shots! See you all soon, thanks for dropping in.
