| Outline of Final Research Achievements |
Due to the progress of urbanization, problems of urban climate such as urban heat island phenomenon, air pollution, etc. are actualizing in many cities. In the coastal cities, the use of the sea breeze to mitigate the urban heat island phenomenon has attracted attention. However, upper air observations data are limited. In this research, to accumulate data for the urban climate in the Fukuoka-Kitakyushu metropolitan area, the fourth largest metropolitan area in Japan and located in coastal area, upper air observation with Doppler LIDAR were carried out. On the other hand, to represent the progress urbanization over about three decades, the National Land Numerical Information land-use fractions dataset for Japan in 1976 and 2009 were utilized in numerical simulations with a meso-scale meteorological model. The results of this comparison suggested that the urbanization process weakened sea breeze penetration.
