"certain atmospheric conditions (like calm and cold nights) could cause the air to stratify into layers that would diffract the microwave, effectively "bending" the signal"
You can see that some times to. We could see a long way from our old house. Pilot Knob was about 9 miles away and we could see much of the land in between.
One day I noticed that things near the horizon were stretched vertically. It was really surprising as I'd never seen anything like it before.
