抄録: | The impact of climate change on sediment hazard occurrence is urgently needed to resolve for pursuing the future sustainable living environment. To this end, this research aims to propose a new approach to physically quantify the change of snake line patterns with the application of Clausius-Clapeyron scaling law. The key of the proposed approach is to establish the physically based linkage among air temperature change on ground surface, peak precipitation intensity, and corresponding snake line pattern of certain percentiles of rainfall events. In this study, we used 99th and 50th percentiles for representing extreme and general precipitation conditions. With the long-term meteorological observation at Kobe meteorological observatory, we successfully verified the applicability of the proposed approach on identifying the change of snake line pattern. The regional climate projections of 5-km NHRCM were then analyzed to examine the future change of Clausius-Clapeyron scaling in the Japanese archipelago. Meanwhile, we also revealed the future change of snake line patterns under climate change influences. |
