Aeromancy is also known as Nephelomancy. It is the art of foretelling future events by the observation of air movement. Aeromancy goes beyond weather forecasting to such things as wind currents, cloud shape and formation, comets and falling stars, spectral formations, and other phenomena which are not normally seen or visible in the heavens.
Some of the different forms of Aeromancy include Eromancy, Austromancy, Chaomancy, Roadomancy and Ceraunoscopy.
