  Cumulus congestus and haze

  The image shows a good example of Cumulus congestus clouds with sharp outlines, dark bases and bright sunlit tops. The most developed cloud over Mt. Vesuvius, in the centre, is of great vertical extent, the upper part having strong sproutings with a cauliflower appearance. The clouds developed quickly on hillslopes in the region, in a light but unstable northerly airflow. A layer of haze can be seen on the left-hand side of the image.

  At 0000 UTC, central Italy lay in an unstable light northerly flow, with a small anticyclone of 1 013 hPa centred near Naples. The anticyclone helped to suppressed convection for several hours after dawn, after which the Cumulus clouds grew rapidly.
