Аннотация:The morphological description of housing development is presented that is based on its basic characteristics: the geometrical profile of buildings, height of buildings, and mutual arrangement of buildings. In analysis, the characteristic morphotypes of urban housing have been selected for which the formation of aeration conditions has been investigated. The homogeneous and nixed morphotypes of perimeter housing development, as well as the homogeneous morphotypes of spot and ribbon developments, have been considered. Investigations have been carried out by numerical simulation. Computation has been fulfilled in the SigmaEco program suite using a microscale model of the urban atmosphere. Simulation data are presented in the form of horizonal velocity fields at a height of 2 m. For each morphotype, velocity distributions along street canyons are shown. It has been found that the geometrical profile of buildings and their mutual arrangement influence the formation of aeration conditions. It has turned out that regions with the homogeneous and mixed morphotypes of perimeter housing development and the homogeneous morphotype of row development provide the most favorable aeration conditions.
