"Does it rain here? I haven't really seen any weather at all."
"Oh, there's weather, when Tartarus is feeling feisty. It rains. Above ground, and below, though there are no pegasi to control it. And it isn't always as simple as water falling from the sky."
It was with great trepidation that Twilight then asked, "What is it, then?"
"Well, a rain of blood, sometimes. Or a tornado of biting beetles, or a freezing fog or a flood of quicksilver. That kind of thing. I've no clue how it works."
"Huh. I guess we've been lucky not to see any of that."
"Yes," said Celestia.

Literature
In what had once been North America, the survivors struggled to prevail in a new age of plague, radiation sickness, barbarism and madness. There were days of seemingly endless night, eerily lit by fires in the sky. Pyrotoxin smogs blanketed the earth. Fetid strontium swamps created new and terrible life forms. Two-hundred-mile-an-hour winds hurtled across the landscape, and when by some freak chance a storm cloud swept in from the sea, it was acid rain that fell — pure acid that stripped a man to the bones in sixty seconds of shrieking agony.

"Frogs fell from the sky for hours. The next day, flaming stones showered us, killing all they touched. Then it snowed for three weeks. Who knows what's next?"
