Impact of Build-Up Areas and Housing Estate Vegetation on Diversity of the Local Climate in Warsaw

The more important research results on the impact of building development and vegetation on the local climate, conducted in Warsaw in the years 1959–2009 by the Department of Climatology, are presented. Majority of the issues associated with determining the deformation of air temperature limits (urban heat islands), humidity and wind vector areas, because of buildings in housing estates, located in various parts of the city, were resolved in master’s thesis. Areas with high building density are characterized by slow cooling and warming pace, especially during the summer months. Spatial changes in the urban heat islands in the east-west direction well describe the latitudinal profiles (W-E) of air temperature differences (∆T ≥ 0) between the city and its urban fringe. The urban heat island ∆T does not appears till 5PM, initially in the Central City District. Spatial diversity of effective temperature and catathermal cooling allowed to mark off in housing estates („Stawki”, „Służew nad Dolinką”, „Sady Żoliborskie”) places with perceptible conditions, e.g. heat, warmth, comfort, cold.
