Outline of Final Research Achievements

Unlike the regional model, the new atmosphere-sea-land-surface coupled data assimilation system is a global data assimilation system using the Global WRF (GWRF) model, which is not affected by lateral boundaries. The GWRF model has a nesting function and enables interaction between the global scale and the regional scale (Greenland ice sheet area). Furthermore, it is advantageous in mitigating the lateral boundary condition problem of the regional WRF model and operating the data assimilation system for a long-term scale stably.
From data analysis, it is pointed out that clear summer warming occurs in the arctic tundra region, and this summer warming decreases the inland water storage amount by increasing the evapotranspiration from the tundra region . Global warming may lead to further dryness.

Academic Significance and Societal Importance of the Research Achievements

最初の結合データ同化システムの論文が、Atmospheric Science Lettersの2017-2018年に出版された論文中、2018年のTop Downloaded paperとして、Wiley出版社から証明書が発行された。さらに、本研究で新たに開発した大気陸面結合データ同化システムは、全球スケールと領域スケールをシームレスにつなぐ事が出来る。
また、再解析データの解析から、夏季の北極温暖化の実態解明につながる、環北極ツンドラ域の乾燥化の解明を行った。これについてはプレス発表によって、研究成果が全国紙や専門紙に数多く紹介され、研究成果の還元と国民に対するアウトリーチ活動に繋がった。
