SCALING OF SNAKE LINE CHANGE BASED ON CLAUSIUS-CLAPEYRON RELATION

Abstract

 We 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, precipitation intensity, and corresponding snake line pattern of certain percentiles of rainfall events. We used 99^th and 50^th percentiles for representing extreme and general precipitation conditions. With the long-term observation at Kobe meteorological observatory, we successfully verified the applicability of the proposed approach. The climate projections of 5km NHRCM were then analyzed to examine the future change of Clausius-Clapeyron scaling in the Japanese archipelago. It is also revealed the change of snake line patterns under climate change influences.
