Daily it sweltered in the punishing sun.
Bubbles gargled delicately,

from Seamus Heaney – Death of A Naturalist on Rap Genius

Meaning

Heaney uses plenty of onomatopoeic language—“gargled,” “croaked,” “slap,” “plop”—throughout the poem in order to create a vivid impression of the sounds in this spot.

The personification of the sun (an instance of the pathetic fallacy) creates a vivid image.
