What is the name of the pattern of constructive and destructive interference that causes successive breaking waves to grow and shrink over several minutes?

Explanation:
The main idea is beating, where two wave trains with nearly the same frequency interfere to create a changing envelope of wave height. When crests meet crests, waves grow larger (constructive interference); when crests meet troughs, waves shrink (destructive interference). This modulation happens over minutes, making the successive breaking waves onshore grow and then fade. In marine science, this onshore, visible pattern of changing surf is described simply as the surf. So this term best fits the observed phenomenon of alternating larger and smaller breaking waves due to interference. The other terms are either too specific or too generic for describing the onshore pattern you see.
