That Dinkum ThinkumFeb 20
I have a question for all the geeks out there: What kind of weather phenomenon creates this pattern on my window? It happens always when it’s below freezing and dry. It only happens on this window, which has no side wall to protect it from... what exactly?

@bigz I suspect it's an effect of the double glazing: It sags slightly towards the middle, so the insulating layer between the panes is a bit thinner, allowing heat from the inside to melt ice on the glass more easily. The heat from the frame then acts towards the edges. This combination creates the ring effect.

@zeitz @bigz Also thought about hat. I wouldn't expect thickness effects causing these differences.
