Bees generally were centered in the hive.  Obviously exhausting heat  out
the bottom.  We had both GLASS box hives and also used IR imaging of  regular
hives.  We've 3-D animations of temp control.  Hives have a  form of
convection current around the outside frames that occurs even when bees  aren't in
the hive.

What amazed us was that when the bees were present, they managed to  turn
the heat gradient upside down, and exhaust through entrance.  Pushing  heat
out the entrance wasn't a surprise.  Seeing it COOLER at the top  was
unexpected.
