What details does Bradbury give to establish the setting of Montag's encounter with Clarisse?

"The air seemed charged with a special calm...."

"...his nose detected a faint perfume, perhaps the skin on the backs of his hands, on his face, felt the temperature rise at this one spot where a person's standing might raise the immediate atmosphere ten degrees for an instant."

"His inner mind, reaching out to turn the corner for him, had heard the faintest whisper. Breathing? Or was the atmosphere compressed merely by someone standing very quietly there, waiting?"

"The autumn leaves blew over the moonlit pavement..."

"The trees overhead made a great sound of letting down their dry rain."

The above quotes detail the setting in which Montag meets Clarisse. The setting is described as one of expectation, like it was destined for Montag to meet Clarrise on that corner at that specific time. Life changing.
