Morphology
The noun phrase is transparently compositional: 'periodic' means recurring at regular intervals and 'event' means an occurrence, so the combined meaning 'an occurrence that recurs regularly' follows directly. This simple adjective+noun pattern is cross-linguistically common and therefore immediately inferable by a B1 learner who knows both constituents.
Etymology
Periodic event gives a simple picture: imagine a bell that rings at the same time every day or a festival that comes back on the calendar each year. The word periodic means it repeats on a set schedule and event is something that happens, so the phrase means 'an event that happens again at regular times'.
