2. Climate and air as planning factors
How climatic elements and air pollution are linked

There is a close relationship between individual climatic elements and air pollution, which is illustrated in a simplified way as follows:

Direct influence on emissions

temperature ┬╗ heating activity, air-conditioning wind ┬╗ blows up dust precipitation ┬╗ binds dust on the ground snow, black ice ┬╗ cars drive more carefully, less traffic clear weather ┬╗ more cruising radiation ┬╗ heating activity, air-conditioning

Influence on evacuation and rarefaction

wind ┬╗ determines direction, transportation, speed and rarefaction inversion ┬╗ prevents upward air exchange radiation ┬╗ reduces inversions, intensifies advection and convection

Formation and reduction of air pollutants

radiation ┬╗ formation and conversion of air pollutants (e.g. ozone and other photo-oxidants) rain ┬╗ leaching of dust and corrosive gases snow ┬╗ chemical reactions at the surface fog, hoar frost ┬╗ separated above the fog phase
