After completing #2012 "Arrowhead Sunrise Sea Smoke and Altocumulus", I turned my easel a bit more to the southeast. The sun was just clearing the distant forest. The Arctic sea smoke was still boiling off the warm waters of Arrowhead Lake. The wolves were still giving the occasional howl as well. A few people were starting to stroll along the beach. It was time for me to pack up and head to Bonnechere Provincial Park.
This really is not an abstract painting. The nature of Arctic sea smoke is one of turbulent thermals rising convectively off the warm waters of the lake. Some spiralling columns developed and this maybe got 20 metres tall. The inrush of air to replace the rising thermal and a slight wind shift is all that you need for these rotating vortices. The vortex tube can be stretched vertically with the more vigourous updrafts. Like a figure skater pulling in their extremities these stretched portions of the tubes rotate faster in order to conserve angular momentum. Sea smoke is also called frost smoke or even steam fog. The backlit fog was strongly illuminated by the rising sun. The thicker portions of the fog were dark while the more wispy and tenuous tendrils were on fire. The scene changed by the second but I was happy to capture the impression of it all.
