Van Gogh Clouds in Finland

Kelvin-Helmholtz Clouds aka “van Gogh clouds”
Taken by Matti Helin on October 29, 2018 in Finland

Helin snapped this picture of “van Gogh clouds”

These clouds, also known as “billow clouds,” are produced by the Kelvin-Helmholtz instability when horizontal layers of air brush by one another at different velocities. It is widely believed that these waves in the sky inspired the swirls in van Gogh’s masterpiece The Starry Night.

In this case, the clouds were traced by the motion of air and painted by the colors of the Arctic sunset. Helin’s video of the phenomenon sets the canvas in motion. Watch it on Youtube. https://www.youtube.com/watch?v=Erd-GVL91Ko

Rain and Fumaroles Over Soufrière Hills Volcano

Photo location: Montserrat, West Indies

(eastern Caribbean island of Montserrat). Taken with an Ipad from the deck of our live-aboard ketch, Roxy.

Photo taken 14 March 2017

Rain and fumaroles over Soufrière Hills Volcano, 4800 feet. The recent eruption in 2005 made quite a shambles of the south end or Montserrat. The hot summit still vents steaming sulfurous clouds that mix with the constant rain cloud formed over this peak. This photo was shot within the exclusion zone as we cruised past. The pyroclastic ash flow also vents steam.
