Abstract
Many recent studies have argued that tropical cyclones will become severer in future warming climate and may cause various catastrophic damages to human life and econ‐ omy. This study explores the impact of climate change on Typhoon Chanthu (2016) by performing a high-resolution (1 km) simulation for current and future climate. We focused on the typhoon intensity, size, heat fluxes, associ‐ ated precipitation and wind speed over northern Japan under global warming with different initial times at 6-hour interval. We find that the typhoon tracks in the present and future climates remained similar, however with stronger intensity and heat fluxes in warming climate condition. In the landfall region of Hokkaido in future climate, the maxi‐ mum wind speed and precipitation amount associated with the typhoon is significantly increased. The results imply that the damages associated with Typhoon Chanthu in future climate over northern Japan would be enhanced through strong wind, heavy rainfall and flooding.
期刊介绍:
Hydrological Research Letters (HRL) is an international and trans-disciplinary electronic online journal published jointly by Japan Society of Hydrology and Water Resources (JSHWR), Japanese Association of Groundwater Hydrology (JAGH), Japanese Association of Hydrological Sciences (JAHS), and Japanese Society of Physical Hydrology (JSPH), aiming at rapid exchange and outgoing of information in these fields. The purpose is to disseminate original research findings and develop debates on a wide range of investigations on hydrology and water resources to researchers, students and the public. It also publishes reviews of various fields on hydrology and water resources and other information of interest to scientists to encourage communication and utilization of the published results. The editors welcome contributions from authors throughout the world. The decision on acceptance of a submitted manuscript is made by the journal editors on the basis of suitability of subject matter to the scope of the journal, originality of the contribution, potential impacts on societies and scientific merit. Manuscripts submitted to HRL may cover all aspects of hydrology and water resources, including research on physical and biological sciences, engineering, and social and political sciences from the aspects of hydrology and water resources.
