Abstract

Due to the rapid growth of the national economies, the architecture of cities is improving and acquiring a diverse and complex typology. Large cities and megalopolises are built up with high-rise buildings, the population density increases, the transport infrastructure is being developed and improved. As a result, unfavorable environmental conditions begin to form in the urban spaces. The formation of the environment in cities with a hot climate, which are a popular destination for tourism and recreation, deserve special attention. The peak of active use of the urban space in hot tourist regions occurs in the summer. Active recreation and tourist flows contribute to the intensity of traffic and increase the anthropogenic load on the city. Additionally, the growing density of contemporary buildings and structures causes pollutants to accumulate in the urban environment, preventing natural air exchange. The southern cities’ mesoclimatic features have been examined. Urban expansion is often associated with conditions that worsen air exchange and contribute to the deterioration of the air environment. Based on the graphic-analytical computation of insolation, the contribution of solar radiation to improving air exchange and the environment has been established.
