‘It was very dark; but in the murky sky there were masses of cloud which shone with a lurid light, like monstrous heaps of copper that had been heated in a furnace, and were growing cold.’From The Life and Adventures of Martin Chuzzlewit (1844) by Charles Dickens.A Cumulonimbus storm cloud grinds across the sky with an arcus feature, or shelf cloud, appearing as a dark ridge along the front of its base.
