The deformation zone on the western horizon of Georgian Bay was on fire with the September sunset. The long and straight arc of cirrus in the sky could only result from the leading edge of the moisture with the warm conveyor belt of the approaching low pressure area. Wisps of cirrus that were precursors of the main area of moisture were strung out parallel to the deformation zone. The atmosphere is stable at the height of the tropopause and these pieces of cirrus were undulating in gravity waves like those on a lake. Although the storm was clearly advancing on Canine Cove, there was a component of the wind from the south creating those waves in the atmosphere. The sunset sky might look chaotic but the message it told was very clear in the plain language of the clouds. There was another autumn storm on the way. It was a fun sky to witness and to paint.
Every painting needs a rhythm. The waves in the cirrus streaks provided the tempo... and the beat goes on.
For a description of how deformation zones form... I blog about the science as well as the art... "
A Closer Look at Lines in the Sky". Art and science are really the same as they examine the natural world around us.
