Completely stationary air is perfectly adequate to stop a bullet - its what stops all bullets normally (unless they hit something).
You could never stop a bullet instantly - so you need to say how quickly you do want to stop it to get an answer.

I think it depends on how dense the air is, obviously the denser the air the lower the wind speed. What ever it is it got to much more that 30 thousands miles an hour as this is the speed of a spaceship as it enters the atmosphere and doesnt stop.
Another question, how far will a bullet travel up before it falls back to the ground

I'm with the answer relating to air density.
Given that a bullet has an aerodynamic shape, and spins, it would need to be faster than the bullet goes when there is no wind.

Wind of sufficient speed to stop a bullet wold blow away buildings and anything else in its path. On earth only a nuclear explosion would create wind speed anywhere near this. Even pistol bullets have muzzle velocity of around 600 mph

It would be on the order of Mach 1. As most muzzle velocities are right around the speed of sound or slightly faster. In any case if you were to fire a bullet into a mach 1 stream of air it wouldn't go very far before it was flung back at the shooter.

The question is rather pointless with a detailed definition of "in its track."
1/2*rho*A*Cd*V^2 is the simplified equation for drag, assuming:
Cd = 0.3
mass = 30 gm
diam: 0.3 in
Vmuz = 800m/s
Vwind = 200 m/s
A bullet under such conditions would decelerated to zero velocity in less than 4 seconds.

The wind never blows that fast on Planet Earth.

That would depend on the velocity of the bullet. (tic)
Not possible to stop bullet with wind.

depending on how fast the bullet is moving the wind would need to exceed that

well on mythbusters ive seen them try to do this i think it was over 200 mph think about it how fast does a bullet move? like 120 mph i think i cant remeber but ur trying to stop it dead on its gonna be alot hope this helps
