Most atmospheric modification that exists in the United States is occurring accidentally as a result of man's land-use changes. Cities, power plants, and certain agricultural activities modify the weather, often dramatically, on local and regional scales. These unintentional changes are so important and widespread that study of their scale and nature is essential in many design and policy areas. Knowing more about inadvertent weather modification has become a part of wise planning for hydrologic, agricultural, transportation systems, and activities. Furthermore, regional weather changes due to man's use of land may reduce or enhance the effectiveness of efforts to purposefully modify the weather.
