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
