comment Hail stones in summer?
Very nice description. Standing at the base of Popocatepet "Its a 18,000 ft volcano close to Mexico Ct." you can actually see this happen. You see the humidity rise from one valley the frozen jet-stream coming of the volcano will carry it to the next sunny valley where you get bearing like hail. This kind of hail is very hard ice and comes down fast. We had to describe the phenomena as part of geo-physics class

Without getting to complicated on the shape and dimensions of the room. I have always suspected a fan introduces more heat in to the room than what it helps dissipate. Unless the wall are cool.

@Mitchell: This point does help. basically the fan prevents pockets of hotter air.
