Periodicity records how regularly, or irregularly, a natural phenomenon actually recurs. Wikipedia notes auroras result from "disturbances in the Earth's magnetosphere caused by enhanced speeds of solar wind from coronal holes and coronal mass ejections," events tied to the Sun's own activity cycle rather than a fixed calendar. This dimension separates phenomena that recur on a predictable schedule from those that strike unpredictably.
