Well, yeah, lotsa water va****...
Seems pretty counterintuitive that a significant amount of it could
remain aloft (and therefore, a problem) for more than a short time,
though. I'd expect that, local to the drop point, the air would go
pretty close to supersaturated, and the vast majority of the water would
almost immediately rain out without carrying very far (comparatively
speaking) from the point of impact. Especially if local sun-blocking
effects from the cloud created were to cause a temperature drop in the
area - Even quicker condensation and rain-out would be my expectation
then.
Wouldn't mind taking a look at that article you mention - is it online
anywhere handy? 1966 was a bit before my subscription got started,
doncha know :) (I didn't "discover" Analog until about 1979 or so, and
then only managed to find a copy s****adically between then and 1982,
when I finally got around to subscribing for a couple years)
