Apologies if this has been discussed before, the search didn't turn up anything. If you enlarge the picture below, especially in the large version, one notices lines the width of all the cabin doors above the doors. Can someone explain what these are/why they're there...?

Draingutters, yes, kinda like all cars and trucks used to have (before they went "aero", of course). You will notice that they are mostly all installed at an angle when viewed from the side to directionally channel water to front or rear, depending on door location, and not interfere with airflow...jack
The front ones (at least on the 737s and some other Boeings) is at more of an angle to compensate for the nose curvature, which you can see in the photo above. The one over the aft service door is closer to being level with the aircraft...
