Morphology

upwelling = upwell (transparent) = up + well + ing

The physical sense 'liquid moving upward' is a direct interpretation of 'up' + 'well' + '-ing'.

Etymology

Upwelling is formed from up and well, with well meaning 'to spring up' or 'to rise'. So an upwelling is when liquid or gas moves upward toward the surface, like water springing up from the ground.
