The influences of meteorological factors on the variability of heat-island structure in the Fukuoka metropolitan area are investigated on the basis of observation data and numerical simulation by using a meteorological numerical model, i.e., Weather Research and Forecasting (WRF). The present results show spatial patterns of the heat island to be controlled by local wind systems. The heat-island intensity varies temporally depending on the formations of sea and land breezes, whereas the variation becomes relatively small under background wind dominated condition. The heat-island intensity takes a maximum value in nighttime and the value depends on the amount of the global solar radiation in daytime.
