Abstract

In stable atmospheric conditions wide urban areas are normally affected by the well known phenomenon called heat island, characterised by a temperature distribution increasing from surrounding rural areas to the centre of the town. The connected heating processes in the canopy layer depend on general meteorological conditions and local properties of the surface. During the day the evolution of the heat island is quite complex but, since it happens only in conditions of strong meteorological stability, the dominant phenomena have a vertical development, while horizontal transfer processes can be neglected. For these reasons the probl
