1 It is a matter of proportions (not directly velocity) called the flammability limits.
2 In order to have a fire you need a fuel and an oxidizer (and energy to start it) but, critically, you need a chain reaction. Imagine that a spark ignites the mixture of butane (fuel) and oxygen in your lighter. If it goes on after the spark it is because the energy released by the reaction of the first molecules that used the initial energy from the spark is now used by another molecules. But, to keep the fire going you need fuel and oxygen ones in the neighbourhood of reacting molecules that can make use of the energy released.
3 In the case there are too many oxygen molecules and few fuel ones, the chain reaction will be extinguished and so will be the fire. Below a threshold called the lower flammability limit (LFL), there can be no fire.
4 The LFL depends on the substance (fuel) and the temperature.
5 You can see now that blowing a candle or a small bonfire has different effects because you are supplying the same extra oxygen to different amounts of fuel. In the case of the candle this extra oxygen will make the mixture go below the LFL, and the flame will be extinguished.

Answer:
Explanation:
the wind blows out weak fires . but it makes the strong fires roar and flourish . it blows out the lamp . but a big fire becomes bigger when the wind blows
