Abstract
“Wind-trail effect” to restrain urban “heat-island” phenomenon is empirically analyzed while several planning and locational variables are identified as influential factors. First, methods for wind-trail effects are generally extracted and categorized based on several theoretical and empirical analysis studies. Secondly, it is evident that there are some different geographic situation in Kitakyusyu City, Osaka City and Sakai City. Finally, wind velocity and direction data in Kitakyusyu City, Osaka City and Sakai City are compared and effective factors are identified.
