Sunset Virga. San Joaquin Valley, California. December 11, 2012. © Copyright 2012 G Dan Mitchell – all rights reserved.

Falling virga drifts below sunset clouds of an incoming late-autumn Pacific storm front

First off, the word “virga” refers to streaks or columns of precipitation that fall from clouds but do not make it to the ground. Virga can often create beautiful, delicate, and gossamer atmospheric effects, especially when the light is just right. In this case the condition was back and top-lit by low sunset light flowing upwards toward the base of high clouds from an incoming winter Pacific storm front.

This evening was (yet another) of those on which earlier unpromising conditions exploded with color right at the end of the day. We had spent the morning photographing birds (mostly geese) at a Central Valley wildlife refuge, taken a short lunch break, and then returned to the refuge for late afternoon and evening photography. The geese were wonderful and we made a lot of photographs, but it seemed like the light was going to “die” before sunset as those high clouds began to drift in from the west. That’s OK, as there are ways to photograph in that more subdue light, but I think we may have been mildly disappointed that the clouds appeared to preclude special sunset colors. So we went about our business of photographing birds, not thinking too much about the sky. Speaking for myself, though, at some point I began to notice a bit of color in the clouds behind the birds. I stopped for a moment and looked to the east (where the sunset colors first are seen before the sweep across the sky toward the setting sun) and noticed that some color was developing. In short order, the underside of the clouds began to light up, and right at sunset we were treated to an absolutely brilliant display of intense color to the west. Since I was shooting with a long telephoto I decided to try a few detail shots of small sections of the sky. If you look very carefully, you might be able to spot a jetliner heading into the sunset.
