数值模拟用于研究区域尺度上陆地生态系统与气候之间的物理和生物相互作用的机制。此外，还研究了区域相互作用如何影响区域大气二氧化碳浓度的季节和年际变化。数值模拟是使用物理区域气候模型进行的，包括复杂的生物地表过程。实验区域为日本列岛及周边地区。区域气候模型可以利用短时间步长（几分钟）和精细网格尺度（约30公里）来估计陆地生态系统与大气之间的非线性物理和生物相互作用。实验时间积分进行了六年零五个月，并对过去六年的结果进行了检查。该模型再现了气象要素的季节变化，并且还相当好地再现了每年陆地表面的热量和水收支。模型计算出的大气二氧化碳浓度的年际变化表现出对流层低层逐步增加的特征现象，与日本上空观测数据相似。模型结果表明，日本上空对流层低层二氧化碳浓度的特征现象与日本列岛及其周围植被活动的年际变化有关。植被活动受到日本列岛周围气候年际变化的影响。通过对影响植被活动的主因子考察，表明试验期间地表向下短波辐射的年际变化是造成植被活动年际变化的主要原因。植被活动的年际变化影响了地表和大气之间净二氧化碳通量的年际变化。反过来，这些变化影响了日本对流层低层二氧化碳浓度的年际变化。
Numerical simulations were used to investigate the mechanisms of the physical and biological interactions between the terrestrial ecosystems and climate on a regional scale. Also, a study was conducted on how the regional interactions influence seasonal and interannual variations of regional atmospheric carbon dioxide concentrations. The numerical simulation was performed using a physical regional climate model, including sophisticated biological land surface processes. The experimental area is the Japanese Islands and surrounding area. The regional climate model can estimate the nonlinear physical and biological interactions between terrestrial ecosystems and the atmosphere using a short time step (a few minutes), and a fine grid scale (about 30 km). Experimental time integrations were performed for six years and five months, with the results of the last six years being examined. The model reproduced the seasonal variations of meteorological elements, and also reasonably well reproduced the heat and water budgets for the land surface for each year. The interannual variations of atmospheric carbon dioxide concentrations calculated by the model exhibited a characteristic phenomenon of stepwise increase in the lower troposphere similar to that found in data observed over Japan. The model results suggested that the characteristic phenomenon in the lower tropospheric carbon dioxide concentrations over Japan was related to the interannual variations of vegetation activity on and around the Japanese Islands. The vegetation activity was influenced by the interannual variations of climate around the Japanese Islands. From examinations of the principal elements that influence the vegetation activity, it was suggested that interannual variations of downward short-wave radiation over the land surface during the experimental period were mainly responsible for the interannual variations of vegetation activity. Interannual variations of vegetation activity influenced the interannual variations of the net carbon dioxide flux between the land surface and the atmosphere. In turn, these variations influenced the interannual variations of carbon dioxide concentrations in the lower troposphere over Japan.
