Camilla Jahns (Member 65,548) must be known by her friends as a cloud expert. One of them called her to step out and look at the sky over Freiburg im Breisgau, Germany and tell them what the clouds were up to. Camilla was thrilled to look up at row upon row of parallel rolls of cloud. Noticing that the rows were low in the sky and aligned perpendicular, rather than parallel, to the wind direction, she correctly classified them as Stratocumulus undulatus. Thank you, Camilla, for your service of cloud identification and sky appreciation.
