Rarely, as the long polar night draws to a close, the sun will suddenly burst above the horizon weeks ahead of schedule. This is the Novaya Zemiya Effect, and it is basically a polar mirage. Even when the sun is still 5° below the horizon, its light can become trapped between thermoclines and be transmitted over the usual horizon. The atmospheric ducts act much like flat light pipes. In the Novalya Zemlya Effect the sun's image is grossly distorted, quite different from the high quality mirages sometimes seen over hundreds of miles in the polar latitudes.

A Coriolus effect has to be better than a Coriolanus effect. Or at least less tragic.
