A wind starts to blow, but doesn't reach the fighters. Then said wind blows a pile of leaves between them, but dies right in between them. Then it picks up again, blowing their hair.
Alternately: A wind blows during the first fight between The Hero and a member of the Quirky Miniboss Squad, but doesn't for the next member. Then when The Hero meets the Big Bad, a wind starts to blow, but the next time they meet, it doesn't.
Averted: The wind always picks up when metereologically appropriate, not when the story demands it.
Enforced: The author always thought it looked cool to have the wind pick up during a fight.
Lampshaded: "Why does a wind always start blowing whenever Bob and Mr. Satan fight? They aren't even outside, this time!"
Exploited: The hero holds Feather of Truth which the villain has to have within a minute. Before engaging combat, a Dramatic Wind blows which the hero uses to get rid of the feather easily so it flies away.
Defied: The hero wears tight clothing and has short hair so that the light breeze that usually causes dramatic wind effects has no visible effect on him.
Discussed: "Why does a wind always start blowing whenever Bob and Mr. Satan fight? They aren't even outside, this time!" "But it always has to pick up in this type of scene!"
Conversed: "It's the unwritten Rule of Cool: Don't start the fight until the wind has disheveled your hair and clothes enough."
Deconstructed: The gentle breeze blows the hero's long hair in his face, distracting him long enough for the villain to kill him.
Reconstructed: The villain, too, has long hair and so they are evenly matched.
