Intra-urban nocturnal temperature differences: a multivariate approach

Eliasson I

The possibility of predicting nocturnal intra-urban air temperature differences on the basis of meteorological data from climatic stations was analysed. Three years of recording at an urban canyon and a nearby open area in the city of Göteborg, Sweden, formed the basis of the analyses. The urban canyon-urban open area temperature differences (DeltaTc-o) were best estimated when the data was first classified with reference to the amount of cloud cover and then fitted to a non-linear regression equation which included the wind speed at the urban open area (10 m level). The study shows that the degree of intra-urban temperature variations can be predicted using a fairly simple methodology. The methodology and the general pattern of the model could be helpful as a complementary tool in urban land use planning for cities with a structure similar to Göteborg.
