Strange Video of Dancing Cloud Explained By Electric Discharge 91

The Bad Astronomer writes "A few months ago I was sent a really weird video showing a cloud snapping around suddenly, far faster than wind could explain. I asked a meteorologist about it, who told me it was due to ice crystals re-aligning when the cloud's electric field discharged. It's pretty amazing to watch, and a great example of how many cool things happen right in front of us that we never notice."

    I watch thunderstorms very closely. 2 summers ago I saw a thunderstorm over my hometown of Baltimore and saw exactly this kind of behavior. It was like the entire side of the cloud tower suddenly bent and twisted around. It looked impossibly huge and fast moving at the time, like a huge piece of sheet metal snapping around suddenly. It definitely smacked of some kind of electrical related effect. Very cool to see this confirmed.

Neutrinos have bad breadth.
