Outline of Final Research Achievements

A new cumulus parameterization which is regarded as a heart of atmospheric general circulation model has been developed based on statistical cloud structure analysis. Past parameterizations have been developed by empirical methods, however, the present parameterization was developed aiming at representing unresolved cloud structure more precisely based on detailed analysis on statistical cloud structures. Using atmospheric general circulation model and atmosphere only climate simulation, the present parameterization could simulate better climatological features and better atmospheric variability than the existing parameterization.

Academic Significance and Societal Importance of the Research Achievements

大気モデルは将来気候を予測する気候モデルにとって重要なモデル要素であり、その中でも積雲対流モデルは全地球規模で大気大循環を支配する、大気モデルの心臓部とも呼ぶべき最重要モデルである。従来は経験的なモデリング手法に基づいていたため、モデルが内包する不確実性を把握することは困難で、物理性能を向上させることも困難であったが、本研究では解像できない雲構造をより正確に表現することに着眼点を置いて、性能向上に成功した。性能向上を実現したモデルは将来予測に役立つだけでなく、モデリングの手法も今後のモデル開発の方法として役立つことが期待される。
