“…The rise of the urban heat island is due to [3]: − reduced albedo variety of artificial surfaces in the city and the geometry of the city, − the revised structure of long-term radiation (heat) in built-up areas, − a small share of natural surface plant, − human activity, − the greenhouse effect accompanying the city. In urban areas are generally not available detailed meteorological data for the determination of the spatial distribution of urban heat island (UHI).…”

Abstract.One of the elements of the urban plans for adapting to climate change is to identify the range the urban heat island (UHI). To a relatively rare ground station network air temperature, one of the possible methods to identify this phenomenon in cities is the analysis of satellite images, and in particular the thermal images surface cities in conjunction with the landuse structure. In the publication is presented the application of indirect methods of determining surface characteristics of heat island in the cities of Upper Silesia Agglomeration on the basis of the analysis of the thermal images from the satellite Landsat for the period 1986-2016. It presents ways to interpret these images depending on the needs of determination the areas sensitive to the impact of the (UHI) and define the areas where adaptation actions to the climate change should be undertaken.

“…Therefore the satellite images of surface temperature of the difference land use in the town can be an alternative method for determining of the spatial distribution of the UHI. This method have been used in many urban areas in the world [1,2,7] and in Poland [3,4,5,6].…”

“…This results in a relative temperature rise in cities in comparison with extra‐urban areas. This phenomenon is called the urban heat island (UHI) (Oke, ; Błażejczyk et al ., ). It depends on a number of factors: those connected with the urban character of the area, such as density and height of buildings (Lopes et al ., ; Gartland, ), a decreased albedo and ground sealing (Fortuniak, ), the extent of anthropogenic heat flux (Papadopoulos, ; Priyadarsini, ) and large, world‐scale factors, for instance the direction and character of circulation which further influence the weather (Kyselý, ; Meehl and Tebaldi, ).…”

Continuous urban development significantly transforms the ecosystem in a big city. The increasing frequency of heat waves and their influence on the rise in mortality in big cities suggest that the thermal hazard (long‐term occurrence of high air temperature) is one of the key climatic hazards of present times. The global temperature rise, reinforced in urbanized areas by the anthropogenic heat flux, leads to intensified convection processes and increased precipitation, especially torrential rain. One of the most important hydrological hazards in a big conurbation is the urban flood hazard. In this paper the identified climatic hazards occurring in a big city are analysed: the thermal hazard and the urban flood hazard. The areas currently exposed to thermal and urban flood hazards in Warsaw are identified and assessed in terms of the hazard level. The results obtained are verified with the data from meteorological measuring stations (the thermal hazard) and from the Fire Department interventions connected with rainfall and flooding (the urban flood hazard). A map of hydro‐meteorological hazards was created by combining thermal hazard and urban flood hazard maps. The approach combining the exposure to thermal and urban flood hazards, presented in this study, uses widely accessible spatial data and can be applied to any location. It can also play a significant role in assessing the adaptation of urban areas to climate change and be an important source of information on the current exposure to hydro‐meteorological hazards as well as their possible increase.

“…Its climate is mostly investigated by means of vegetation based methods (e.g., Réthly, 1933; Ács and Breuer, 2013; Szelepcsényi et al ., 2014). The vast majority of human‐based methods consider human body energy balance equations characterizing the environmental thermal load as simply as possible via thermal indices as, for instance, PMV (Predicted Mean Vote) (Fanger, 1970), PET (Physiological Equivalent Temperature) (Mayer and Höppe, 1987; Höppe, 1999), UTCI (Universal Thermal Climate Index) (Jendritzky et al ., 2009; Fiala et al ., 2011), PT (Perceived Temperature) (Staiger et al ., 2012), HL (Heat Load Index) (Błażejczyk and Krawczyk, 1994). Among these PET (Matzarakis et al ., 1999) obtained great popularity.…”

A human body-clothing-atmosphere environment system energy balance model is constructed to evaluate individual human thermal climates in the Carpathian Basin. The analysis is performed in terms of clothing resistance and operative temperature for the period 1971-2000. The model's main strength is that it simulates the metabolic activity rate M as simply as possible taking into account interpersonal variations. Non-sweating, walking humans are considered in natural outdoor conditions at a walking speed of 4 kmÁh −1. Atmospheric data are used from the CarpatClim dataset; human data are taken from a Hungarian human dataset. The dataset reveals that the interpersonal variations of M of walking humans can reach 40-50 WÁm −2. According to the results, the variability of individual human thermal climates can be significant. This variability increases towards cold climates and is less in the comfortable thermal zone, when the operative temperature is between 23 and 28 C. It should be mentioned that summer is thermally neutral in the Little Hungarian Plain, the Great Hungarian Plain and in larger parts of the Transylvanian Plateau, irrespective of the person considered. The warmest areas in the Carpathian Basin can be found in Bačka and Banat. In terms of thermal sensation, the results obtained agree well with the results referring to the human considered in the Physiological Equivalent Temperature index model.
