Back again! Within a month. Well, nearly.
Greetings anyway and thanks for dropping by. It’s a bit of a hotch-potch this post, I went through the pictures I have lodged chronologically and they were all over the place (or rather I was all over the county taking them) but I hope that you find them to your liking. I did think I was going to be able to go on to a water based theme, then this moved to clouds and then to beaches so…woops.
Anyway, how about the weather in Wales then? For those who aren’t fortunate enough to live in this area, it has been humid. Phew. I work in an office that has air conditioning but this is essentially for show, as it broke down in the first year or so of me being there and has never been fixed…we have Japanese tourist buses call in on occasion wondering quite how we retain such ancient cooling systems without spontaneously contracting Legionnaires. However, I’m more of an open window guy but even that hasn’t helped, as wind has been in short supply. However, this are changing, a little fresher and drier to come the weather people say. Mind you, weren’t they the ones who failed to predict the famous 1987 storm?! Anyway, cynicism aside, onwards to the pictures and associated nuggets of information…
Firstly, on the partial water theme and following on from my images of the boats last week, I ventured once again down to Port Lion and was fortunate to see evidence of one of the highest tidal ranges in the UK (upwards of 25 feet in the highest tide). In this instance, just a wet mark was left but, bear in mind that as you continue down the slip, there is usually a considerable stretch of beach to stand on which is underwater, that’s a whole heap of H2O….
Quite what possessed the owner of the house down at the bottom of the lane to think it was a good idea to build there confuses me, but build they did. Of late, the property has been revamped as well and it has a pretty awesome view but what does he say to his insurance company in the event of a disaster? I imagine the conversation would go something like this….
“So, how did the property flood?”…”Erm, it was a particularly sticky tap when I was running a bath upstairs….for a day…with mud in it”…”So, how do you account for the seaweed?”….”I like Japanese food and was hosting a sushi party?”. Hmm.
Moving to less ridiculous things and away from my twisted sense of humour, the next images are from one of my favourite beaches, Newgale. This place is packed during the Summer but, if you are a resident you get to see it at the best times, during Winter and Spring when it is quiet and sunny. As well as being a blue flag beach, which is one of the cleanest going, it is very beautiful in pretty much all weathers off season. Some of you may remember that this beach featured in my blog earlier when I posted some images of the ancient forest that had been uncovered by recent storms. In this incarnation though, I need the sand to give the effect I wanted….
Also, it appears that (unofficially) this beach marks the marks the boundary between English and Welsh-speaking Pembrokeshire, with the next beach north of Newgale being called Pen-y-Cwm. It also made an appearance in a music video (Delerium – Silence)…yes, you can see it here …Pembrokeshire on the tinterweb. Who’d have thought?
It wasn’t going to be long before I moved onto weather was it? Lenticular clouds. What? Yes, quite a rare occurrence around here, but there was a little rash of them not so long ago, only small, but they were there. Let me explain…..as air flows along the ground, it encounters obstructions like water in a flood would. These are every day objects, such as buildings and bridges, as well as natural features, like hills…in my case, the Preseli Hills. All of theses things disrupt the flow of air into eddies. The strength of the eddies depends on the size of the object and the speed of the wind. It results in turbulence, of a sort. Where stable moist air flows over a hill, a series of waves form. If the temperature at the crest of the wave drops to the dew point, moisture in the air may condense to form lenticular clouds. I admit, the ones I saw were not as dramatic as the link….
Here, you can see that the clouds have degraded into the waves I spoke of earlier…probably due to a change in the wind speed or direction. Not quite as pretty, but it demonstrates the principal.
In some circles, these clouds are referred to as UFOs (or “visual cover” for UFOs), particularly the round “flying saucer” type in the link pictures, because these clouds have a characteristic lens appearance and smooth saucer shape. Also, because lenticular clouds generally do not form over low-lying or flat terrain, many people have never seen one and are not aware clouds with that shape can exist. Bright colours are sometimes seen along the edge of lenticular clouds making people think they are other-worldly. However, they can form where a mountain does not exist, usually as the result of shear winds which are, again, not so common.
As an aside, the term flying saucer was created by an early documented sighting of “vehicles” over Mount Rainier by an amateur pilot, Kenneth Arnold. He described flying shapes moving “like a saucer if you skip it across water”. However, I’m sceptical…as per the description above, where are you most likely to see these clouds? Yes. Near mountains. It is quite a regular sight in the area, as per this picture by NASA.
Anyway, I took some further pictures later on of the further degradation and now that the wind had dropped and the moisture had increased, so had the cloud cover and there was a nice blanket of clouds with a slight asperitas feel….
I love the folds and lines in these types of clouds and you can pick up the shapes of the lenticular clouds in places if you look carefully. Nice. I admit, I should probably have smoothed this image of noise as it was dark, but the PC was protesting at this point, so you’ll have to forgive me!
Well, here endeth the prattle. If you have stayed on this long without just scrolling down the pictures, well done! No, thanks for that, all criticism and requests gladly taken but remember, don’t nick the pictures for your wallpaper! Ask me. I am happy to email full resolution copies upon request. All my details are in the blog, I don’t bite and won’t charge unless you ask me to print one, that’s a whole different kettle of fish…
Thanks again, see you all soon for more Pembrokeshire based picture based nuggets!
