Well, actually it's just the reverse.  The soft top is curved (looking at it 
from the side..) like a wing.  The air moveing over the top is accelerated, 
which causes a drop in pressure in the area above the top.  This does make the 
pressure under the top greater, but not from air blowing in, it's just the 
principle some guy named Bournolli ( sp) came up with.
