I'll be darned. I wonder how and/or if this affects lightning?

Surprising Clouds Forming Due to Lead in Air

Since the 1940s, scientists have known that seeding clouds with lead can hasten ice-crystal formation and precipitation, said atmospheric chemist Dan Cziczo of the U.S. Department of Energy's Pacific Northwest National Laboratory.

"But this is the first time we've found that lead in the environment, inadvertently added by human activities like burning coal, is having the same effect," he said.

"What we need are follow-up studies to explore how this might change precipitation patterns," Cziczo noted

I was digging around in this thread today and thought I'd breathe some new life into it with this strange cloud phenomena I found.

These clouds are very cool looking and the fluid dynamics behind them are equally fascinating.

velly nice!! the animation struck a chord as i blogged about a power generation scheme a while back that uses this vortex effect. >> Scientists to tap river currents to create clean energy

Here's a bizarre cloud formation filmed in Moscow. I'm thinking it's really an unusual ring in the blanket of clouds that's either thinner or cloudless allowing light to penetrate.
