Here are some pics. I'll add more captions when I have time.
They are (from top to bottom, left to right):
A tornado which struck Topeka, KS in the 1950s
The tornado which struck downtown Nashville a few years ago
A tornado which struck downtown Miami a few years ago
A tornado somewhere in Oklahoma
Enjoy!
