Outline of Final Research Achievements

Based on the results of laboratory experiments on characterization of various aerosols as CCN and INP conducted using MRI cloud simulation chamber as part of this research, we developed aerosol-cloud-precipitation integrated parameterization. It was implemented in the cloud resolving (non-hydrostatic) model, CReSS, developed at Nagoya University. By incorporating the three-dimensional information of various atmospheric aerosols from the global (aerosol climate) model, SPRINTARS, into the cloud resolving model, CReSS-4ICE-AEROSOL, as initial and boundary conditions, we simulated the precipitating clouds that occurred around Japan during the warm season and the diurnal convection clouds that occurred in the arid and semi-arid regions.
It was confirmed that this model properly reproduces aerosol effects on cloud / precipitation using the results of aircraft observations obtained from previous studies and the results of ground-based aerosol monitoring conducted as part of this study.

Academic Significance and Societal Importance of the Research Achievements

雲核や氷晶核として働くエアロゾルの雲・降水影響は日々の天気予報から気候変動予測まで様々なスケールで重要な役割を果たしていることが認識され、1990年代からその影響に関する研究されてきたが、不確定性の軽減には至っていなかった。本研究で開発したモデルを用いたシミュレーションを行うことによって、エアロゾルの雲・降水影響、特に降水雲を介したエネルギー・水循環の変調を解明・評価し、天気予報および気候変動予測の精度向上につなげることが可能となった。波及効果として、このモデルは人工降雨・降雪などのエアロゾルによる意図的気象改変の効果を正確に評価する手法としても利用可能となった。
