Abstract

 In coastal city, it is thought that the sea breeze has great influence on summer diurnal temperature distribution patterns. Understanding the spatial distribution of sea breeze effects will be helpful for making Urban Environment Climate Maps. Consequently, this study aims at making the maps of sea breeze effect distribution using the observed data and the numerical simulation results in Hiroshima plain. The results are revealed as follows: 1) The effect of sea breeze for mitigating urban warming is relatively larger in coastal area and the effect is smaller in the inland area. 2) The spatial distribution patterns of sea breeze effect for mitigating urban warming being made from the numerical calculation is similar to the one which is made from the observed temperature. 3) The temperatures in the area which are affected by sea breeze are also influenced by surrounding ventilation condition (SVC). On the other, the temperatures in the area which is not affected by sea breeze are not influenced by SVC.
