Where I live in Southern California, we often have skies so boring that most people don't look up much. Partly it's smog, and everybody knows about that. Sometimes it's smoke from brushfires, which everybody also probably knows about. At other times, we have clear skies but cloudless, and again, why look up?
On the other hand, over the last several years, I've noticed something strange. Southern California skies are starting to become more interesting. Take the shot above. I took that with my G1 cell phone at about 7:50 a.m. in January, 2009. It is not a typical sky around here!
What's happening? What's the connection?
