Megjegyzések:	The climate of built-up regions differs significantly from rural regions and the most important modifying effect of urbanization on local climate is the urban temperature excess, otherwise called the urban heat island (UHI). This study examines the influence of built?up areas on the near?surface air temperature field in the case of the medium?sized city of Debrecen, Hungary. Mobile measurements were used under different weather conditions between March 2002 and March 2003. Efforts concentrated on the determination of the spatial distribution of mean maximum UHI intensity with special regard to land?use features such as built?up ratio and its areal extensions. In both (heating and non?heating) seasons the spatial distribution of the UHI intensity field showed a basically concentric shape with local anomalies. The mean maximum UHI intensity reaches more than 2.0 ?C (heating season) and 2.5 ?C (non?heating season) in the centre of the city. We established the relationship between the above?mentioned land?use parameters and mean maximum UHI intensity by means of multiple linear regression analysis. As the measured and predicted mean maximum UHI intensity patterns show, there is an obvious connection between the spatial distribution of urban thermal excess and the land?use parameters examined, so these parameters play a significant role in the development of the strong UHI intensity field over the city.
