While walking with my wife in our suburban neighborhood, we spied this cloud iridescence or irisation.
Though not uncommon, this irisation occurred in a cirrocumulas cloud. Irisations usually occur close to the sun, which you can see in the photo. It was at the leading edge of the atmospheric river system that pummeled southern California.
I checked the radar when we returned home and found that the rain clouds ran from Virginia’s Shenandoah Valley to Dallas, Texas.
But where does the word “irisation” originate? You can thank Iris, the Greek goddess of rainbows and the messenger of Zeus and Hera to us earthlings. Since I obviously received this colorful communication, I wanted to pass it on to you.
