Nacreous Clouds

[Polarlow]

Some pics of Nacreous clouds taken from Dundee this morning, I have already posted them in the Scottish regional thread, but thought I would share them here.

Superb pics! Saw them from Fife as well but later on and the colours were washed out by then.

Hello everyone,

This is my first post in this nice forum. I am a PhD student in University of Manchester. I work on weather radars (specifically in dual-pol radars). However, I've liked weather and atmospheric phenomena since I was a child. That's all for me.

Here I collected a couple of photos from nacreous clouds occured last week over the UK. Photos are not mine as you can see. Enjoy:

My blog has a few photos from Edinburgh and East Lothian and the video from my house, but there was a bit too much sunlight by then. At least I saw them

I take it we all realise the significance of these stratospheric clouds?  

Since their ample appearances over the N.Hemisphere this winter ( and warm temps over the trop in the Arctic?) I should say folk might need to concern themselves over the record Arctic Ozone hole of 2011 being beaten this March as a result of the cold temps , and chemistry, over the polar region???

Update for Dec 2018, very cold air above us in the Stratosphere, but that's only one ingredient https://www.netweather.tv/weather-forecasts/news/9319-what-is-so-special-about-nacreous-clouds--mother-of-pearl-polar-stratospheric-clouds pic Duncan Mc

There was a particularly good display  2 years back after a lively weather system passed through
