On Weather blog:
I took this photo a few days ago (with my trusty new Olympus SZ-30 MR),
showing a spectacular example of a "sun dog". An example of parhelia,
sun dogs are triggered by sunlight being refracted (bent) off hexagonal
ice crystals about 25,000 feet above the ground. Cirrus clouds act as
billions of microscopic prisms, bending white light into the colors of
the rainbow. Pretty cool.
I agree; I'm particularly impressed that the sun dog was bright enough to be reflected by the water in the lake.

My grandmother taught me that a sun dog means that a change in the weather is coming (usually within 24 hours). I think this might be due to the fact that if there are clouds about, it might be a front, etc.
ReplyDeleteIn any case, it has been a remarkably true rule of thumb.
