The wind is usually smooth, with no temperature by its own. It flows and not retains what it drags for long time.
Fire is energy, light and heat as well. But too much, consume.
The wind stirs the fire. Fire warms the wind ... This is symbiotic and has two things to teach:
If the wind blows hard into the fire, it will burn more ... but quickly, it will run out of fuel and after a while there will only be a tiny flame. And with no more stuff to consume, the dying flame is going to disappear,
And if the fire is exceeded with the wind when this just down from the cold of the mountain, the air will become abrasive, unbearable.
So, it's better to have a steady wind and a controlled fire.
