Glacial ENSO and Atlantic Meridional Overturning Circulation - Link to model results

Numerical experiments using the general circulation model CCSM3 have been performed for glacial climates: Last Glacial Maximum (LGM), Heinrich Stadial 1 (HS1), Marine Isotope Stage 3 Stadial (MIS3-ST) and Marine Isotope Stage 3 Interstadial (MIS3-IST). As a reference, a control simulation for preindustrial climate (PI) has been performed. Details of the experiments are described in Merkel et al. (2010).

The datasets contain timeseries from the last 100 years of each model simulation.

For each experiment, we present:
- annual mean timeseries of the maximum of the Atlantic Meridional Overturning Circulation between 30°N and 80°N and below 500 m.
- monthly mean timeseries of sea surface temperature area-averaged over the Nino3-region (5°S-5°N, 150°W-90°W).

本研究采用通用环流模式（General Circulation Model）CCSM3，针对冰期气候开展数值试验，试验涵盖末次冰盛期（Last Glacial Maximum, LGM）、海因里希冷期1（Heinrich Stadial 1, HS1）、海洋同位素阶段3冷期（Marine Isotope Stage 3 Stadial, MIS3-ST）与海洋同位素阶段3间冷期（Marine Isotope Stage 3 Interstadial, MIS3-IST）。作为对照，本研究同步开展了工业前气候（preindustrial climate, PI）模拟。该试验的详细细节可参见Merkel等人（2010）的研究。

本数据集包含各模式模拟时段最后100年的时间序列数据。

针对每项试验，本数据集提供如下内容：
- 30°N至80°N、500米以深水层中大西洋经向翻转环流（Atlantic Meridional Overturning Circulation）最大值的年平均时间序列；
- 尼诺3区域（5°S-5°N，150°W-90°W）内区域平均海表温度（sea surface temperature）的月平均时间序列。
