THE IMPACT OF CLIMATE CHANGE ON LONG-TERM CLIMATIC CHANGING TREND USING PRECIPITATION OF METEOROLOGICAL OFFICE DATA IN JAPAN

Abstract

 The impact of climate change especially has been becoming apparent after 2018 Japan floods, was reported as included the effect of global warming for the first time. Therefore, it is important to consider the impact of climate change in future flood control plan. However, in the previous studies, the timing when the impact of climate change begun to appear has not been revealed based on observational meteorological data. Accordingly, this study aims to clarify the timing when the impact of climate change begun to appear based on CCI (Climate Change Indices) with precipitation of meteorological office data in Japan. As the result, we confirmed that the timing when the impact of climate change begun to appear may be around 2014 in whole Japan. Additionaly, it is found that the timing is vary spatially.
