Outline of Final Research Achievements

For gas absorption process, MstrnX was not simulated well in case of the quadruple CO2 condensation because it is assumed the doubling CO2 condensation in the previous version. In this study, we revise this model to correspond the quadruple CO2 condensation with the update of database. For particle scattering process, ice crystal habits was assumed sphere, so we modify it can be adopted the hexagonal column and aggregate particle. Moreover, large particle scattering are introduced, that is able to calculate the radiation effects of fog, rain, and snow particles that could not be calculated using the conventional method.

Academic Significance and Societal Importance of the Research Achievements

本課題研究で改良された放射伝達モデルにより、温暖化時の気温上昇について精度の良い推定が可能となった。また、氷粒子の非球形形状や大粒子の散乱計算を新たに導入することで、これまで考慮されていなかった雨粒や雪粒の放射への寄与や、氷雲の影響のより性格な算定が可能となった。近い将来での気候変動の推定にはGCMによるシミュレーションが不可欠であり、より精度の良い放射伝達モデルを提供することは気候予測のみならず、都市インフラの異常気象への対策にも役立つと考えられる。また、本課題研究で改良された放射伝達モデルは様々なモデルに既に導入されているため波及効果が予想される。
