This is a followup to my post of July 16th on weird weather phenomena.

I'd heard the term lenticular clouds before but didn't think to include it at the time - see also here and here - heck, you can just Google up loads of examples.

Not quite a weather phenomenon, perhaps, but mistpoeffers or "the Barisal guns" is (are?) an interesting atmospheric phenomenon.

Seems there's also been some recent developments in the search for the elusive red sprites and blue jets that sometimes occur above thunderstorms; also, although it's not news as such (other than being news to me), it seems that the visible return stroke of lightning strikes is preceeded by emissions of X-rays, gamma rays, and beta particles ("fast-moving electrons"). Who knew?

Finally (at least for now), no roundup of lightning-related phenomena would be complete without at least a passing reference to ball lightning - anecdotal evidence here, scientific speculation on its nature and origins here, and a pair of Kiwi researchers who think they know what causes it here.
