Climate in cities

More

City modifies the local climate due to the density and character of the built-up. Materials used to construct the buildings, streets etc. also play important role. All those factors change radiation, heat and water balances of a city. Urban bioclimate is the subject of research for bioclimatologists; they study how urban climate effects living organisms, mainly humans.

Air pollution in urban areas has a great significance for human health. Energy production, industry and transportation deliver various kinds of air pollution. For example acid rains, caused by the sulphur and nitrogen oxides delivered to the atmosphere, cause not only soil degradation and acidification of lakes, but also economic losses, due to faster corrosion of metal elements used outdoor. Also buildings get effected, especially those built of limestone, marble etc. There have been many attempts to reduce air pollution. The systems of air pollution monitoring are established in the endangered regions. International cooperation led to many agreements and treaties which help to improve air quality in global scale.
