Distribution of air pollution and its microclimatological conditioning with Tarnów city as an example

Rozkład zanieczyszczeń powietrza i jego mikroklimatyczne uwarunkowania, na przykładzie miasta Tarnowa

Summary: Tarnów is a medium size industrial centre. The field of pollution immission in the region of Tarnów is controlled mainly by emission from the chemical plant 'Zakłady Azotowe' (Nitrogen Works), and from some smaller plants and transportation emission which are growing in importance. The relative heights within the area of the town in the E-W transect reach ca. 60 m while in the NW-SE transect - 180 m. Anticyclone synoptic situations add up to degradation of the sanitary conditions of the air. However, they can have a positive influence on the distribution of air pollution in the town during the non-heating season. Location of the town at the outlets of the valleys and the occurrence of the urban heat islands, during the periods of air stagnation, leads to the development of nocturnal systems of gravitational winds which can cause a decrease in the concentration of pollution in the centre.

Słowa kluczowe (w języku angielskim): air pollution, sanitary conditions of air, urban climate, microclimate.
