I know it because the Bible talks about it in a literal sense.

Wind can move so softly that it can hardly be felt.
Sometimes air moves slowly and the wind is barely noticeable.
Wind can be simply as air in motion in any direction. In most cases the horizontal component of the wind flow greatly exceeds the flow that occurs vertically.
Wind is moving air, a big layer of air in the atmosphere surrounds the Earth. Air within this layer moves from place to place when it warms up or cools down.
When the weather is clear we may experience a gentle breeze, when the wind is still very light but we can feel it on our faces and in our hair, and we may hear leaves rustling. At other times, the air can move very quickly and become a gale or hurricane, blowing down trees and damaging cars and buildings.
Wind develops as a result of spatial differences in atmospheric pressure. Generally these differences occur because of uneven absorption of solar radiation at the Earth's surface. Wind speed tends to be at its greatest during the daytime when the greatest spatial extremes in atmospheric and pressure exist. Wind Speed and Wind direction are the 2 characteristics of winds.
Wind facts:
Wind legend - the Ancient Greeks used to think that wind was the Earth breathing in and out. We now know that it is just air on the move.
Wind power - windmills usually face into the prevailing wind - ie: the direction the wind blows in most often.
Wind strength - the world's windiest place is Antarctica, where winds blow at more than 100 km/hr for 5 months of the year.

You can't ever prove *any* theory to be true, that is a logical impossibility. All you can do is show that a theory agrees with all empirical data, and that predictions made using the theory are in fact observed in the real world. Even if a theory has never been shown to be false, it is still never *proven* to be true.
You know there is a force that moves clouds around in the sky, swirls leaves around, generates waves on water surfaces, and keeps kites aloft. The theory is that these effects are caused by the motion of air molecules, and that the friction, or drag, between the air and solid or liquid surfaces is the way that energy from the wind is transferred to other objects (there are also theories for how this happens at a molecular level). There are also theories as to how these winds are generated in the atmosphere due to pressure gradients, temperature gradients, moisture transfer, the rotation of the earth etc.
All of the available empirical evidence suggests that the fundamental theory (wind is air molecules moving around, dragging things along with them) is correct, but it can never be proven. There could be forces we are unable to measure or see with our current sensors, tiny winged air elves with brooms perhaps, that are really what moves clouds around and generate waves on the ocean. So while it is extremely unlikely the theory of "wind" as described above (the air moving, not the air elf one) is untrue, you can't ever prove it definitively.

If something has 4 legs, and it barks like a dog - then it is a dog.
In a very fundamental manner - the existence of things is synonymous with their effects.
You appear to differentiate taste or view from other effects.
Taste is the effect of stuff on our taste buds.
View is the effect of stuff on our light receptors.
Every observation regarding ANY phenomenon or object can be experienced ONLY through its effects - directly or indirectly - on our senses.
In this sense: either you can prove nothing, or you can prove the existence of wind just as you can prove the existence of the computer you are using to read this.

In science, you disprove prove things through experiments, you do not prove them. You can demonstrate that wind is real without looking at effects of wind through an experiment that tracks the movements of gases in the atmosphere by observing the movement of chemical odors or a chemical tracer. The null hypothesis is that if no wind exists, odors would disperse only through diffusion. Diffusion would be relatively slow, at rates predictable by temperature and pressure (Boyles law), and occur randomly in all directions.
If you released a gas with a traceable odor in windy conditions, you would disprove the absence of wind by observing that the rate of dispersal exceeded the rate that would occur through diffusion, and that the dispersal did not occur in a random direction, but instead traveled in a particular direction.

sure you can. wind is really air moving, right? so the proof of air moving isn't that hard. you could put radiotracers in the air, you could use fog to make the air visible, you could use heat sensors to watch a front of hot air moving.
But aside from that, the proof is in prediction. I can make wind with a fan, and I can predict exactly how it's going to behave. In science, that's as close as you get to proof: to prove a theory, you make predictions and test them. If they all hold true, your theory is sound. if there's even one failure, the theory is wrong.

For arguments sake, everything is known through the senses, so your probably agitated by the fact you can't see it. But a blind person can't see you but would never doubt that you exist. If it's not nothing, it's something. and that is not how nothing acts.
