Quote #1
The woods crashing through darkness, the booming hills,
Winds stampeding the fields under the window
Floundering black astride and blinding wet (2-4)
The wind's power is compared to a stampeding herds' power because it isn't necessarily aware of what it's doing. It doesn't intend to destroy anything, it's just a side-effect of its nature.
Quote #2
then under an orange sky
The hills had new places, and wind wielded
Blade-light, luminous black and emerald,
Flexing like the lens of a mad eye. (5-8)
The wind seems to be lording its power over the world at this point, using the "blade light" as a symbol of its lordship.
Quote #3
Once I looked up—
Through the brunt wind that dented the balls of my eyes
The tent of the hills drummed and strained its guyrope,
The fields quivering, the skyline a grimace,
At any second to bang and vanish with a flap; (10-14)
This exaggerates the wind's power for effect, yet again. It couldn't actually blow the world away, but the fact that it seems like it could is telling.
