Song of the Buoyant Spirits (Rev. #3)

[RiverNotch]

I think this is better. Title's much smoother now, I think, though it implies a level of subjectivity that is missing from the poem. That is, at first glance, I thought this was a song sang by those buoyant spirits, not by what seems to be a passive observer.
Rev. #3: Song of the Buoyant Spirits

Crying with joy,
buoyant spirits thrive; laughter rings out, Not sure about "thrive", especially with the rough placing of these buoyant spirits. Are they spirits of sky, or of rain? I first imagined they were spirits hogging the flood like, well, boats floating on water, with that epithet, but this might be just me. Still, "thrive" implies some level of continuance that isn't as seen here.
loud exclamations of freedom and victory Yes, roars implies loud, but "loud exclamations" sounds like a bit of a mouthful, which is worse. Better to split this from the earlier, possibly with an exclamation point.*
reverberate from sky to ground.
Crowned in cumulonimbus, the mosaic of earth is cleansed, Break "is cleansed", maybe? And cleansed, rinsed, and bathed may be too synonymous to really work here, without any real progression in strength.
rinsed, bathed,
swathed by the clouds. If it's already crowned in clouds, then this to the earth is redundant. "Round and revolving" was better, though not by much. And my mind keeps screaming "swaddled in cloud" is better, but that's mostly just me.*
Oust, for a day, the parching sun!
Thunderstorms are gifts, you see:
rejuvenation for all canopied by the sky. Much better ending.

* - That is,

"....laughter rings out!
Loud exclamations...."

and

"....the mosaic of earth
is cleansed, rinsed, bathed,
swaddled in cloud."
