Morphology
The head noun 'swell' already denotes a long, smooth sea wave, so learners who know that word will grasp the basic idea of a wave; the modifier 'ground' suggests something to do with the earth or depth/origin below the surface, giving a partial cue. However, the specific sense that this is a broad, deep swell caused by distant storms or seismic activity is not directly predictable from 'ground' alone and likely requires prior exposure, so the expression is only partially transparent.
Etymology
Ground swell may come from sailors who felt a long, deep swell that seemed to rise from the ground under their ship and move the whole boat. So, the name helps you picture 'a broad, deep wave' that can travel far and rock ships or surfers.
