Article Published on Mitigating Disasters Caused by Heavy Rainfall in Urban Areas

A research group led by Kenta Irie, and Prof. Tetsuya Takemi of the Disaster Prevention Research Institute (DPRI), Kyoto University, aimed to mitigate disasters caused by heavy rain in urban areas.  They revealed through computer simulations using a supercomputer that reducing the amount of heat emitted from buildings and the ground in urban areas is an effective way in controlling cumulonimbus clouds that develop rapidly in summer afternoons which can cause local heavy precipitation and flooding, particularly in urban areas.

Due to the effects of urbanization and global warming, there are concerns that urban weather disasters will become more severe. In particular, heavy rain disasters occur almost every year, and countermeasures against them are a socially important issue.

Results of this research “Effects of modifying surface sensible heat flux on summertime local precipitation in urban areas of Osaka, Japan” were published online in the international academic journal “Theoretical and Applied Climatology” on 12 May 2025.
