Title

融雪に伴う湿地形成が気候に与える影響に関する研究

Abstract

融雪時の表面流出の一部を一時的に貯留するタンクによって表現する湿地スキームを陸面モデルMATSIROに組み込んで、陸面オフライン実験による感度実験を行い、湿地の持つ貯水効果が、陸域水循環や地表面の熱収支に与える影響の評価を行っている。

Model Characteristics

MATSIROは気候モデルMIROC・NICAMなどの標準陸面モデルとなっている。

Computing Environment

京やES3のような大型計算機のほか、Linuxベースのワークステーション等でも動作する。

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
This is the dataset simulated by MIROC5-AGCM. Two experiments were conducted with and without a scheme implicitly representing a snow-fed wetland, in which snowmelt can be stored with consideration of subgrid terrain complexity. The spatial resolution is T42, which corresponds to a gridcell size of about 310 km at the equator, and the model has 40 levels in the vertical. We used climatological monthly sea surface temperature (SST) and sea ice distributions from 1979 to 1996 as boundary conditions. We conducted a 30-yr simulation with zero surface storage as an initial condition.
