Possible outbreak of polar stratospheric clouds underway around the Arctic Circle


A possible outbreak of polar stratospheric clouds (PSCs) is underway around the Arctic Circle, SpaceWeather.com reports.

Ivar Marthinusen sends this picture of the phenomenon taken on December 22, 2014 from Skedsmokorset, Norway:

"Right after sunset, these clouds were so bright they were uncomfortable to look at directly."

PSCs, also known as nacreous clouds from nacre, or mother of pearl, due to its iridescence, are clouds in the winter polar stratosphere associated with the formation of ozone holes. They float much higher than ordinary clouds, from 15 – 25 km as opposed to 5 – 10 km, and produce unforgettable colors during the hours around sunset.

Although their precise chemistry and details are not fully understood they are the medium on which reservoir chlorine compounds are converted into ozone-destroying chlorine radicals.

PSCs form at temperatures of around minus 85ºC, colder than average lower stratosphere temperatures, and are comprised of ice particles ~10µm across. The clouds must be composed of similar sized crystals to produce the characteristic bright iridescent colors by diffraction and interference.

Here's another picture of the same phenomenon. The PSCs are flying high above the darker cirrus clouds at the bottom of the picture.

  1. geoengineering has no effect on our climate. If anything the aluminum goesin our soils and effects us that way..Look up how to much aluminum effect the humon body. Look back at the 1600’s and 1800’s and why the earth cooled back then, was it caused from geoenginneering?

  2. I agree with middleway. I have witnessed these countless times embedded in geoengineered aersoled clouds yet never before this program which is the most obvious and heinous I have ever seen, yet the sheeple sleep on. many are waking up, albeit too slowly. the lies keep coming though. all the mainstream media is controlling the minds of people. this includes magazines, newspapers, radio and most especially the tell lie vision. https://www.youtube.com/watch?v=T3TFBJPAJ_w

  3. I took some video footage of these type of clouds about a week ago while driving home, and we live about 12deg south of the equator in tropical northern Aust. Been a strange wet season so far too, rain falls down to approx 20% of a normal year.
