Brendan, > What you describe here is Sub Refraction as opposed to Super refraction. > Sub refraction (is upward bending) and as per Mariners Handbook: "can occur > when cool air flows over a relatively warmer sea" Which is exactly opposite to the conditions that apparently existed. However, I suspect it could be relevant that we observed from the shore. It was really hot, and the sand on which we stood was warm, then the sea is shallow near the shore... Alex.
