Wave clouds south of the Alps, seen by Meteosat-10 on 14 April.

The High Resolution Visible (HRV) image, 14 April 10:00 UTC, shows the 'backbone' of the wave clouds was quite straight and oblique, in relation to the range of the Alpine crests, a rather unusual feature. Also, the structure was very complex.
Viewed from below, under the central section of the wave clouds, altocumulus lenticularis could be identified, topped by thick cirrus.
We documented a similar event in the same area in 2007. The case study includes a time-lapse video of the clouds from below. High-level mountain wave clouds over the Po Valley
