The air is continually motion, yet it’s invisible and hard to recognize until it moves leaves, blows smoke, or cools us on a hot day. You have seen how wind is an extremely powerful force that moves storms and weather systems across the globe and is a major determining factor in the climate of any specific area. Wind also transports heat, moisture and a variety of other things (dust, pollen, insects, birds, etc) from one place to another.
