A recurring theme of mine over the years has been that of a katabatic wind: the gentle stream of air that flows down a mountainside overnight. Indeed, I wrote about it fifty years ago, again this year with 23 cm/s, and with many postings in between.
Barney Gilmore, who has a grand view across the North Arm of the Lake, today sent me a wonderful picture illustrating a katabatic wind. It was taken in the light of dawn and shows smoke (from slash burning) being transported down the mountain slope and out over the Lake by a katabatic wind.
I am really impressed with such compelling illustrations of a physical process as this.
