  Altocumulus stratiformis opacus undulatus

  The sky appears covered with a layer of Altocumulus, indicating the species stratiformis. The greater part of this layer is thick enough to mask the Sun completely (variety opacus). Cloud elements, clearly visible at the top of the photo, have merged into broadly parallel lines that are transverse to the observed wind in the layer (variety undulatus).

  This cloud should not be confused for Altostratus, which is characterized by its uniform and mostly featureless appearance.

  A weak cold front passed across the Czech Republic and an occluded front was moving eastward through the area.

  Altocumulus stratiformis opacus

  The grazing illumination makes the relief of the sheet of Altocumulus opacus, which covers the right half of the photograph, particularly evident near the horizon, where ripples and waves at 1, 2 can be seen. At a lower level, at 3, a patch of Stratocumulus is observed, apparently formed out of the convective clouds which developed during day-time but subsided during the evening. A quasi-stationary front, with an Altostratus-Nimbostratus system, oriented NNW-SSE, was lying over Sweden. The station was situated exactly at the western margin of the withdrawing cloud system, which at the place of observation had degenerated into Altocumulus.
