Investigations concentrated on the urban heat island (UHI) in its strongest development during the
diurnal cycle in Szeged, Hungary. Task includes development of statistical models in the heating and non-heating
seasons using urban surface parameters (built-up and water surface ratios, sky view factor, building height) and
their areal extensions. Model equations were determined by means of stepwise multiple linear regression analysis.
As the results show, there is a clear connection between the spatial distribution of the UHI and the examined
parameters, so these parameters play an important role in the evolution of the UHI intensity field. Among them the
sky view factor and the building height are the most determining factors, which are in line with the urban surface
energy balance
