yeah i thought it had to do with the 'ground atmosphere' as well.. cause i read somewhere thats why seeing was worst lower to the horizon.. as to the gentle breeze.. makes sense.. if you thing of things that cause bad seeing as a 'fog' type thing... it's harder for fog to 'form' and settle when there's a breeze.
it's also why they have smog alerts in the cities if there is going to be no wind and all the pollution and stuff just sits and collects.
