Urban environment as a factor in the formation of the area microclimate

Abstract

The growth of the leading countries’economies leads to the rapid development of megacities and changes in urban areas. Currently, more and more modern high-rise civil buildings are being built, resulting in an increasing density of urban areas and the activity of transport infrastructure. This causes major changes in the structure of urban development, which leads to a change in aeration and microclimatic conditions in urban areas. Solar radiation plays an active role in shaping the microclimate of the urban space, which aggravates the heat and wind regime of the urban environment. This is especially acute in the southern cities with hot climatic conditions. The article analyzes modern urban areas and factors affecting their microclimate. The role of temperature inversions in the formation of microclimatic conditions is indicated. Using the example of the yard space in Dushanbe, measurements and field studies were carried out; graphs of the climatic indicators of the urban area were plotted. The role of solar radiation in the formation of convective flows and microclimatic conditions of urban space is discussed.
