mbl.is has the answer. :) Impressive cloud feature.

Huh? That sky looks in the pic and was indeed crystal clear and very clean. (A week in such clean fresh air was very tiring!) No volcanic eruptions within 5000 miles upwind as far as I know. That was a very long range shot of Yesa too as it was many miles away. Looks perfectly clean to me! Even the cleanest air has some dust particles (or else clouds would not form) and over such long distances they are bound to have a scattering effect on the light.
Clouds do not have to be white and fluffy to be clean. They will appear grey if viewed at the right angle even if they are in sunlight. Especially thin lenticulars (thin simply because it is a thin layer of moisture at that location). The building clouds look whiter because they are thicker and have more angle to them. I’ve seen these effects many times from oblique angles in both dirty and super clean air.

Thanks H. :)
The full set of images are now uploaded onto my own website at http://www.flybywire.org.uk/pictures/Jaca2015.html – The Facebook album is a subset of this album (294 pictures in total). More lennies, sunset shots and other goodies from the ground and in the air.
Cheers!

For some reason my posts weren’t appearing. Maybe the forum doesn’t like images in links? (was trying to make the pics clickable linking to the pic on my CAS album.)
A few new pics from my Spanish Gliding expedition:
Soaring above the Spanish Pyrenees on 25th March 2015. Clouds from the French side flowing over the peaks and down the Spanish valleys.
Wave soaring above the Spanish Pyrenees on 26th March 2015. This wave bar took us all the way to the airspace ceiling at 19,500 feet.
Clouds over the Yesa Reservoir in Northern Spain on 27th March 2015. Seen while climbing in wave over Santa Cilia.I have a Facebook album up at https://www.facebook.com/media/set/?set=a.10152736154607797.1073741848.648887796&type=1&l=7cf6bf0797 and eventually far more pics will go on my website. :)

Nice wave bars indeed. I saw similar as I ascended from Zaragoza, Spain en route to London, UK on Sunday 29th March. I didn’t think to try a time lapse out! Maybe next time.

This last week I’ve been busy processing a zillion pics from a gliding expedition last week to the Pyrenees. At its best I was soaring high on mountain wave, passing and climbing above lenticular clouds on my way up to a best height of 19,500 feet. The trip was cloudspotter eye candy with lots of lenticulars of all shapes, rotor clouds, as well as the more humble stratus, cumulus, cirrus, etc. Even the Ryanair flight in and out of there was fun with snow showers over the pyrenees on the way in, and a sky full of lenticulars on the way out before we ascended into cirrostratus and lost sight of it all.
Now if only my (so far dismal) UK gliding season could finally get going then that would be great!
A few pics were added to the Lasham Expeditions blog at http://lashamexpeditions.blogspot.co.uk/ – one of my favourite shots was posted on Week 4 Day 4 (from Thursday 26th March 2015) as we descended from 19,500 feet, still above some exsquisite sculpted lenticular wave bars.
This is the pic, probably in the region of 15,000 feet above sea level, Pyrenees peaks (snow caps hiding behind the lenticular wave bar) and France beyond to the right, Spain (Aragon) and Santa Cilia / Jaca to the left:
I have already removed the blue colour cast from the glider canopy tint since this was posted so on my own site it will look better.-Mike
One of my favourite UK cloud gliding pics from 2009:

Hehe you’re making me drool now. I’m glad there was a glider pilot reference in the first link. They needed some pics from in a glider though. Such as:

I’ve experienced the Fohn first hand, at Deeside Gliding club in Aboyne, Aberdeenshire. One day in October the entire country was grey and damp, except for NE Scotland where the Fohn effect gave us warm and sunny conditions.
Another September when heading North up the A1 the remnants of hurricane Katia hit the UK. West of the Pennines the weather was pretty damp. But in the lee of the Pennines a Fohn effect meant it was glorious warm sunshine, but mighty windy. It was hard to stay in lane on the road! As soon as we turned off and followed Hadrian’s Wall over the pennines we found low cloud and drizzly rain as we stopped at Housesteads Roman Fort.
Another Fohn like effect last September was in Cornwall. With a warm moist Southerly Breeze the South Coast was cloaked in fog all day. When we drove to Padstow on the North Coast that side was clear of the fog in warm sunshine. Perfect for Cornish Ice Cream!

Here’s another superb timelapse. This is specifically for New Zealand’s weather. Of particular note to me are great timelapses of a lenticular cloud at 1:10 and 2:50 and a mesmerising asperatus timelapse at 2:43.
Looks like the lenticulars are focussed on in a short timelapse here:

I clicked on Edit for the very first post in the topic and it looked as if I could change the topic’s title as well as the main text.
The title edit box only appears for the first topic. I think the UI could be better there, like having a specific Edit option for the title itself rather than embedded within the first post edit dialog. But looks simple enough once you know how.
-Mike
Here’s another time lapse. Worth seeing for the shots from the top of a hill with fog below. It looks very much like a turbulent ocean in fast forward.
One or two nice crepuscular ray sequences too.
UPDATE: The same guy also posted this epic ‘Into the Atmosphere’ timelapse and is clouds almost throughout. Some spectacular sunrise/sunsets, fog, cunims and lightning, and more. Wow!
-Mike
As one of the moderators I am able to change the topic title. I can do so if you want. Or just leave this new topic in place and refer to it from the old one which was correct historically?
-Mike
No problem Gavin. Weekend is better for me anyway as it means I don’t have to book time off work. And by the end of September the gliding soaring season should be more or less over too so more able to commit (although last year I had a surprise good soaring flight in early October which started to make up for a duff year). I’m sure it’ll be worth the wait. And will be great to meet you too Gini and everyone else.
