Clouds of Colour

Summer has finally arrived. After a day of cloudless, sunny skies some high level cirrus clouds moved in, the precursor to a brief front bringing moisture but no rain.

Cirrus clouds are wispy streaks of ice crystals above 8000 metres (26,000 feet). "Fall streaks" form when ice crystals fall through changing high level winds. The forming streaks can be straight, shaped like a comma or all mixed up together.

Just before sunset, the cirrus clouds captured rays of sunlight to form a small sun dog. The ice crystals in the clouds can form colourful patches 22 degrees to the left or right of and parallel with the sun, something like a mini-rainbow. What a nice way to end a nice summer the day on Powell Lake in Coastal BC. -- Margy


  1. Great captures Margy, especially your cirus or "mares tails" as I knew them as a kid! Hope the hiccup in the weather is temporary!
    Have a wonderful weekend.

  2. that's serious cloud work there. Love your stories of nature on the blog!

  3. I like your photos of clouds; it looks like God took a paint brush and lightly touched the sky with the cirrus clouds in that first photo.

  4. Thanks for all the comments. I love looking up at the sky and finding beautiful clouds. - Margy

  5. I sure love your big skies. I miss our lake!
