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."
