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 is creating a lot of violent effects at this point of the poem—probably knocking off some branches and maybe felling some old trees—but it's not really that destructive. It's more that it's presenting the threat of violence.
Quote #2
[…] and wind wielded
Blade-light, luminous black and emerald,
Flexing like the lens of a mad eye. (6-8)
The wind wields "blade-light," but what does it really use it for? It's not actually going to annihilate the world or kill any humans (apparently). Again, it's just representing a threat. It could be a deadly if it wanted to be, and it moves like a mad eye because it isn't exactly rational.
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)
The wind couldn't really blow the world away, but this exaggeration helps dramatize its power.
