A layer of altocumulus above what appears to be low-lying stratus clouds formed via homogenitus, as a result of the nearby power plant and a variety of particles that act as condensation nuclei. This view overlooking Uskmouth Power Station, South Wales, is from Portishead, Somerset, England.

This picture of cirrus cloud looks almost like dense white smoke floating delicately in the sky and quickly being drawn together by the turbulent air currents up there. From Rebecca Hill, Canberra, Australia
