Meteorological Air-Pollution Potential of the West Siberia Territory in the Climate Warming Period

Abstract

The change of the meteorological air pollution potential MAPP (analog of the APP) is performed over 196 weather stations of West Siberia in the period from 1986 to 2010 - the climate-warming period - is analyzed. It is revealed that the meteorological conditions for impurity scattering in the bottom air layer changed to worse side almost overall the region territory because of an increase in repeatability of weak winds of 0–1 m/s with a simultaneous decrease in repeatability of winds ≥6 m/s. Two causes of this phenomenon are put forward, notably, climate warming and partial overgrowth of weather observation sites. The interrelation of MACP trends with ACP 4 trends, which confirms the fact of increasing the air pollution in region cities upon worsening the meteorological conditions, is found. The hypothesis is put forward that a similar phenomenon can also occur on other territories of the Russian Federation, which should be taken into account when planning and placing the productive assets of the country.
