The urban climate changes which took place in the Fukuoka City area between 1925 and 1988 due to the land use change was studied by numerical calculation. The three-dimensional turbulence closure model was applied for the simulation. The calculation procedures were similar to those adopted in the authors' previous study. The land surface parameters were obtained by using LANDSATTM data for 1988, while those for 1925 were determined from the old maps of the Geographical Survey Institute with the aid of GIS techniques. Model calculations were carried out for the two years using these land use and other physical parameters. The calculated temperature and wind distribution maps for the two years were compared to detect the quantitative and topographical changes in temperature distribution which were caused by the land cover changes between the two years.
