Okay, maybe not fire, but something just as cool…
This is a massive discharge of electricity from the top of a cumulonimbus cloud. Notice the blue color? That’s indicative of low humidity in the area. Lower humidity = lower voltage required for a discharge = greater distance lighting can travel. You can see how this makes for an potentially dangerous situation. And also potentially beautiful.
There’s a whole slew of pictures like this with extensive science-y type information here.
But even more impressive than that is this picture taken in Switzerland after a rain storm in sub-zero temperatures.
Simply amazing. I’d love to know what kind of tree that is. If a storm like that happened in the southern U.S., it would flatten every tree in the region.
I found this on the same website as above, lifeinthefastlane.ca. It’s a really cool site and you should peruse it for a while.
