  Cumulus congestus

  Cumulus are detached clouds, generally dense and with sharp outlines. They develop vertically in the form of rising mounds, domes or towers. The sunlit parts are mostly brilliant white, with a relatively dark and nearly horizontal base. Cumulus congestus, as seen in this image, are strongly sprouting Cumulus clouds of moderate to strong vertical extent (at least 2 to 3 km) with the bulging upper part resembling a cauliflower. These clouds may produce precipitation in the form of showers, and in this instance a thunderstorm was reported in the vicinity shortly after the image was taken. Congestus usually develops from the species mediocris. Cirrus can be seen near the top of the image.
