Well, you said "for real..."
Wind is the result of air moving from an area of high pressure to an area of low pressure. Different air masses moving around cause weather and change the air pressure in an area. Think of wind as moving down a "slope" - when there is a big difference between the pressures of air masses in an area, the slope is steep, and when there's a small difference, the slope is shallow. Shallow slope = low wind, and a steep slope = a high wind (this "slope" is called the pressure gradient). So if a high pressure air mass is right near a low-pressure one, that gradient is very "steep" so you get high winds.
Hope this helps. It was probably more than you needed to know.
