The low-lying damp ground can produce a visual effect known as a Fata Morgana when the Tor appears to rise out of the mist. This optical phenomenon occurs because rays of light are strongly bent when they pass through air layers of different temperatures in a steep thermal inversion where an atmospheric duct has formed. The Italian term Fata Morgana is derived from the name of Morgan le Fay, a powerful sorceress in Arthurian legend.
