Re: Rain Sheets, why?

[roger haar <haar@soliton.physics.arizona.edu>]

Hi,

	One additional piece of the puzzle is that since large drops fall 
fast that small drops (different terminal velocities), large drops sweep 
out an volume below them an grow as they accumulate small drops.  

	I am told that very small drops tend to repell ( maybe many of 
them are charged)

Thanks
