This is a very nice poem. It uses alliteration and onamotpoeia to recreate the feel of a storm. The line and syllable count do not follow any pattern that I can see. I almost wondered if it was supposed to be a shape poem (The poem sort of resembles a cloud), but I don't see any pattern for that.

The note at the end from Scientific American is very interesting and it does give the poem a little more power, although I admit that I am a bit prejudiced against a poem that requires some explanation like that. Actually, the good news is that the poem is powerful without it.
