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).
