Unravelling the Mysteries of Lightning

Cloud enthusiast, Mark Hyde, recently contacted us about the Atmosphere-Space Interactions Monitor (ASIM) which is a state-of-the-art, unique collection of optical cameras, fast light meters and X- and Gamma-ray detectors, that will for the first time, will allow researchers to observe lightning in the Earth’s atmosphere with unprecedented detail from space.

The monitor will study the inner workings of lightning allowing us to have more understanding of the impact of lightning on the atmosphere.

There is an in-depth and fascinating article about this on the University of Bath website.

Science Explains “Rough and Chaotic” Cloud Feature

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.

Munch inspired by ‘screaming clouds’

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.

A Reassessment of the Solar Geometry of Constable’s Salisbury Rainbow

Professor John Thornes (member 26) is an expert on the depiction of weather in art. 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.
