Title: Illuminated night clouds
Post by: Zirfeld on 05 July 2017, 21:50:02
They are beautiful! Only visible end June / early July , if the sun is not far under the horizon. They are far above normal weather. 50...80 kilometers up in the stratosphere. Soft waves at the northern horizon. Normal clouds are under 9 kilometer, except extreme thunderstorms reaching 12...15 kilometers attitude, breaking the troposphere, but illuminated night clouds are far above. The highest clouds on this planet. I like to sit in the garden and simply watch them.

Can`t say I`ve seen them  ??? maybe a continental European thng

just fair weather clouds melting away this evening  following a vivid  sunset.
Enjoyed a barbie supper with the family, followed by a cold Heineken or 2

Unusual, caused by meteor vapour trails apparently. My wife is currently in Germany with her twin sister so I will ask them if they can observe it in Dortmund? 8)

You keep posting pictures of your rusty old wreck but, when something is worth seeing, no pictures.  ;D

Moin together

Illuminated night clouds are in the upper stratosphere. Normally air is very dry there, so clouds can not exist. In Midsummer (Northern Hemisphere June/ July) there a little more water damp in the stratosphere, so sometimes special clouds can develop in up to 80 km high. Because the sun is only a few degrees under the horizon, these stratospheric clouds are illuminated by sunlight.

It is not a continental phenomen, but north in Scandinavia it is not visible, because sun stands to high. Also in southern counrtys like Spain or Italy it is not visible, because the sun is to far below the horizon.

I found a nice picture, taken in Essex, UK

@STEMO

Thank you very much for your song of praise. You know my challenge! Be sure my rusty wreak will come to the wreaking party of your actual car ;D

I once was in Florida and witnessed beautiful cloud to cloud, high level lightning.

Nature indeed can still impress :-* :-* :-*

Hi Lizzie

There is much more, we do not understand. Example: Red sprites. They are lightnings, going straight 100 km above. Hundreds of millions volts are needed for that. No one knows where this voltage came from. 100 km attitude is borderline to space. Outside is nothing.

Really?

Hi!

Yes, man knows nothing yet!!   We think we do, but in reality we have only just touched the surface of scientific knowledge ;)

As for space I believe there is massive levels of electrical energy in that expanse of "nothing" that can be harnessed on day by space transportation vehicles. It is possible other life forms are already using it to zip from dimension to dimension.  ;)
