The primary aim of this study was to reveal quantitatively what effect urban structure has
on the development, magnitude and spatial distribution of the annual mean maximum urban heat island
using a selected representative sample area in Szeged, Hungary. In order to quantify what effect urban
structure has on the development of the mean urban heat island a relatively new surface parameter
(weighted volumetric compactness) was used that characterises the volume, structure and thermodynamical role of buildings. This new parameter was used in conjucntion with other established surface
parameters. How the new parameter and other surface parameters can pinpoint the magnitude and
structure of the heat island was investigated. The compactness of approximately 11 000 buildings in onethird of the town was determined by geoinformatical analysis. A stepwise multiple linear regression
model was used to determine to what extent each parameter adds to the annual mean urban heat island
intensity. According to the results presented here, the connection between compactness and the annual
mean (?all weather?) heat island intensity is stronger than with the sky view factor. Using this modelequation, the absolute deviations of the generated heat island (calculated for an independent 1 yr period)
remained under 0.5°C throughout almost the entire investigated area of Szeged. The structure of the
estimated heat island with its characteristic features showed clear similarities to the real conditions.
