What am I seeing?

It's a very rainy evening as our plane goes into the landing phase over Barcelona; my window seat is just over the front edge of the wing, and we're below the clouds. As I look outside, alongside the plane, lit by the steady wing lights, there are perfectly horizontal, continuous strings - of slightly variable thickness - of rain. (At the wing tip, the flashing white beacon singles out perfectly horizontal, short stringlets of rain.) I know that rain doesn't fall sideways, so: what, exactly, am I seeing?
