The question was raised as we were discussing the effects of wind chill as 
stated in message ID:931057677.En ... An Engineer friend of mine said that 
if the water and air were 33 degrees (F) and a wind was passing over the 
water, the energy required for evaporation would "supercool" (his term) 
the water and cause the top layer to freeze. This was in contrast to our 
understanding at the time, but has caused us to give it some serious 
thought (except for one who refuses to believe anything that isn't in 
print :-))
