- Аннотация: Climate change over the central part of the East European Plain has been governing by global changes of the greenhouse gases, aerosols, and regional variations of atmospheric circulation. Within large urban area, climate change (especially the warming) is amplified due to influence of sharply modified land properties. It can be characterized as the urban amplification of the heating. The focus of this paper is the climate change of the Moscow megacity, including changes of the structure of the atmospheric boundary layer, changes of the urban heat island (UHI), and determination of the microclimatic features of the local environment. Available meteorological observations within the Moscow urban area and surrounding territory allow us to assess the human-induced climate warming component separately from climate variations inherent to the whole the central part of the East European Plain. To obtain more precisely viewing on the UHI structure we have included into the analysis together with the ground observation the satellite data (Meteosat-10), providing temperature and humidity profiles with high resolution. Today, integrated climate management is an important approach for sustainable management and protection of large city areas. One of the core challenges for such successful program is the assessment of climate change impacts on the local microclimate changes as well as related socioeconomic sectors. In this context, the results of the regional climate model COSMO-CLM+TEB were used to investigate the mechanism of the urban amplification. Climate change differences between urban and rural areas are determined by changes of the shape of the UHI and their relationships with changes of building height and density. Therefore, the urban module of COSMO-CLM+TEB model is fed by information from special GIS database contenting both geometric characteristics of the urban canyons and other characteristics of the urban surface. The sources of information were maps belonging to the OpenStreetMap, and digital elevation models SRTM90 and ASTERGDEM v.2 as well. The multiscale GIS database allows us to generate such kind of information with different spatial resolution (200, 500 and 1000 meters).
