Urban heat island (UHI) is a region of increased air temperature in the canopy layer and boundary layer of the atmosphere above the town or industrial agglomeration in comparison with rural surroundings. The difference in temperature increases with the size of the city. This study describes the dependence of the intensity UHI Central European cities on their size and position of their weather station. It uses a multiple linear regression model. The dependent variable Y entering the model (data from 40 cities) are UHImean and UHImax. They are calculated as difference in air temperature between the urban and the relevant rural weather station. The average intensity of the urban heat island (UHImean) is the average value of the UHI of all available data in the analyzed period (hourly measurements of air temperature [řC] for the years 1994-2012). The data are only taken from night times records between 21:00 and 4:00 UTC and on days with the average total cloud cover at the city weather station less than 0,5. The maximum intensity of the urban heat island (UHImax) is the average maximum value of the UHI per night. The data are taken under the same conditions as in the case of UHImean. Independent variables X are the size of built-up area (X1) and the position of the weather station calculated using the...
