Basis of the atmospheric spreading process

The purpose of this lecture is to show how the spread of impurities or pollution in the air (or more generally, of atmospheric properties) is closely tied to atmospheric flow. This is represented by a great variety of different large movement systems, whose order of magnitude (scale) extends from 104 km down to the mm range. The study of spread processes thus includes the whole of meteorology. A series of examples help to make this clear. (orig.)
