Prediction of Changes in Global Storm Surges and Waves Due to Global Warming – Evaluation of Coastal Disaster Risk in Coastal Areas of the World-

  • Research Reports

Joint research was conducted by Assoc. Prof. Tomoya Shimura, Prof. Nobuhito Mori and Assistant Prof. Takuya Miyashita of the Disaster Prevention Research Institute (DPRI), Kyoto University, the Argonne National Laboratory in the United States, and the Meteorological Research Institute of the Japan Meteorological Agency to predict future changes in global high tides and waves due to global warming.


Future global warming can change the intensity of waves and storm surges as well as rising sea levels. Therefore, in order to adapt to climate change in coastal areas, it is important to predict future changes in storm surges and waves in addition to general sea level rise. In this study, it is shown for the first time the future changes of global storm surges and waves that have been evaluated separately, based on the continuous climatic conditions from the past to the future reproduced by the global climate model.


The results of this research were published online in the international academic journal “Geophysical Research Letters” on 14 March 2022.
