Wind is: 1. air in natural motion, as that movng horizontally at any velocity along the earth's surface, caused by temperature differentials in air. 2. a gale, storm; hurricane. 3. any steam of air, as that produced by a bellows or fan.
I looked up the meaning from: Random House Webster's College Dictionary.
I hope this is what you were looking for.

Wind is actually an indirect type of solar energy. Wind is due to the fact that different surfaces on Earth absorb solar energy at different rates. For example, soil, water, air all absorb varying amounts of solar energy. The hot air above the Earth's surface rises and this reduces air pressure near the surface.  It is replaced by colder, more dense air that sinks below it. This creates a movement of air which is known as wind. Winds move from high to low pressure. This movement of air has kinetic energy and this energy, when captured and harnessed can be transformed into electrical energy or mechanical energy. This has been done for years with windmills.
