I called the local LPR (Liberal Public Radio) station when they had a   
   meteorologist guest, and asked about the song. Nobody on the show that day   
   knew the song, which did not help with communication, but he said it sounded   
   like a line squall, and that    
   seems reasonable to me. As the sun goes down the air could cool from the top,   
   and in a large flat area in a "sultry Summer calm" the cooler, more dense air   
   might not break through for quite a while, so then when it does get started   
   there would be a lot    
   of energy available. On a dark night I suppose there would be nothing to warn   
   anyone until the wind hit the ship, and  then what they would see is that the   
   ##!%&# weather went from calm to 100 knots.
