Earth & Space Science News recently published an article about the asperitas cloud formation, the newest entry in the International Cloud Atlas. It includes commentary from Giles Harrison, an atmospheric physicist at the University of Reading, UK and Gavin Pretor-Pinney, founder of CAS, who together investigated the science behind asperitas. The team suggests that the new feature owes its appearance to oscillating streams of moving air contained with it and goes on to explain why asperitas forms.
It’s a very informative piece and you can read it in full here.

Noctilucent clouds are extremely high ice-crystal clouds that form up in the mesosphere, at altitudes of around 50 miles / 80 km. Their Latin name roughly translates as ‘night shining’. This is because these ghostly rippling clouds only become visible when the Sun is below the horizon for the observer, so that the sky is dark by the sunlight still catches their gossamer forms. Most commonly viewed between 50° and 70° north and south of the equator, noctilucent clouds are made of ice crystals and can only be observed in either hemispheres during the summer months, which is when the mesosphere is at its coldest. ForNorthern-Hemisphere cloudspotters, therefore, the noctilucent cloud has just begun. Keep an eye out towards the northern horizon in the few hours before sunrise and after sunset for the best chance of spotting these mysterious and ghostly formations. Here is a taster video beautifully filmed over Denmark by Adrien Mauduit of what noctilucent cloud spotters at high enough latitudes might be lucky enough to observe.

Matthew MacKenzie, member 42913, spotted this article on the BBC News website.
In 1892 Edvard Munch painted The Scream and in the background the sky in full of colourful wavy lines. Scientists from Norway have theorised that these are probably Mother of Pearl or Nacreous clouds. These clouds are usually spotted two hours after sunset or just before sunrise and are extremely bright with vivid, shifting iridescent colours.

He has recently had an essay published in Tate Magazine in which he solves a puzzle about the rainbow depicted by the English landscape artist, John Constable, in his painting Salisbury Cathedral from the Meadows. Professor Thornes’s work is a great demonstration of how science can inform art and vice-versa.
