地区性的综合环境模型系统 RIEMS 2.0 结合了一个化学喷雾器模型,普林斯顿海洋模型 POM 被采用在东亚上在大气的循环和喷雾器的直接放射的效果 DRE 上模仿地区性的海洋的影响。在这研究考虑的喷雾器包括专业人为的喷雾器例如和自然喷雾器例如,土壤灰尘和海盐。RIEMS 2.0 被 NCEP/NCAR 分析 II 驾驶,并且模仿的时期从 1 月 1 日到 2006 年 12 月 31 日。结果显示出下列 1 由有 POM 的 RIEMS 2.0 的海平面的压力是的模仿的年度平均数比没有在大陆上的 POM 低、没有在海洋上的 POM 更高。2 在夏天, RIEMS 2.0 与 POM 模仿的副热带的高度更强壮并且进一步向西延长,并且大陆人低是比没有在夏天的 POM 强壮的。3 光深度 AOD 与 POM 由 RIEMS 2.0 模仿了的喷雾器比没有 POM 在长江的中间、更低的活动范围是更大的。4 没有 POM,有 POM 的直接放射的效果是比那强壮的。因此,作者应该在在长期的模拟学习直接气候效果喷雾器上考虑地区性的海洋模型的影响。
The Regional Integrated Environmental Model System (RIEMS 2.0) coupled with a chemistry-aerosol model and the Princeton Ocean Model (POM) is employed to simulate regional oceanic impact on atmospheric circulation and the direct radiative effect (DRE) of aerosol over East Asia. The aerosols considered in this study include both major anthropogenic aerosols (e.g., sulfate, black carbon, and organic carbon) and natural aerosols (e.g., soil dust and sea salt). The RIEMS 2.0 is driven by NCEP/NCAR reanalysis II, and the simulated period is from 1 January to 31 December 2006. The results show the following: (1) The simulated annual mean sea-level pressure by RIEMS 2.0 with POM is lower than without POM over the mainland and higher without POM over the ocean. (2) In summer, the subtropical high simulated by RIEMS 2.0 with POM is stronger and extends further westward, and the continental low is stronger than without POM in summer. (3) The aerosol optical depth (AOD) simulated by RIEMS 2.0 with POM is larger in the middle and lower reaches of the Yangtze River than without POM. (4) The direct radiative effect with POM is stronger than that without POM in the middle and lower reaches of the Yangtze River and parts of southern China. Therefore, the authors should take account of the impact of the regional ocean model on studying the direct climate effect &aerosols in long term simulation.
