      With my amateur eye I’m guessing these are either Undulatus or Fibratus – am I close? Can anyone confirm?IMG_6892IMG_6891

      Hello Tess  Nice spottings! Fibratus and undulatus are often difficult to distinguish. The difference between the two is that undulatus has its wave pattern perpendicular to the wind, while fibratus has its streaks in the direction of the wind. This is not yet very helpful because we can’t see the direction of the wind, but we still can see the texture of the clouds. And in this case I think we see undulatus, because of the smooth rounded forms the lines have. Fibratus would have a more streaky cirrus-like signature.

      Greetings,

      Hans
