RAPID To What Extent was the Little Ice Age a Result of a Change in the Thermohaline Circulation?: HadCM3 model outputs

"To what extent was the Little Ice Age a result of a change in the thermohaline circulation?" project. This was a Natural Environment Research Council (NERC) RAPID Climate Change Research Programme project (Joint International Round - NE/C509507/1 - Duration 1 Aug 2005 - 31 Jul 2008) led by Dr Tim Osborn of the University of East Anglia, with co-investigators at the University of East Anglia and Royal Netherlands Meteorology Institute. The dataset collection contains various model experiment output used in an analysis of whether the Little Ice Age climate could have been generated by one or more of the following factors: a weakening of the Atlantic thermohaline circulation; the persistence of a generally negative North Atlantic Oscillation; or reduced radiative forcing (by increased volcanic activity, reduced solar insolation and lower greenhouse gas concentrations relative to the present). Rapid Climate Change (RAPID) was a £20 million, six-year (2001-2007) programme for the Natural Environment Research Council. The programme aimed to improve the ability to quantify the probability and magnitude of future rapid change in climate, with a main (but not exclusive) focus on the role of the Atlantic Ocean's Thermohaline Circulation.“小冰期在多大程度上由温盐环流（thermohaline circulation）变化引发”研究项目。该项目隶属于自然环境研究委员会（NERC）RAPID气候变化研究计划（联合国际回合——NE/C509507/1，执行周期为2005年8月1日至2008年7月31日），由东安格利亚大学蒂姆·奥斯本博士牵头，合作研究者来自东安格利亚大学与荷兰皇家气象研究所。 本数据集收录了多组模式实验输出结果，用于分析小冰期气候是否可由以下一种或多种因素驱动：大西洋温盐环流减弱；北大西洋涛动（North Atlantic Oscillation）持续呈现整体负位相；或是辐射强迫（radiative forcing）降低——具体途径包括火山活动增强、太阳入射辐射减少，以及相较于当前水平更低的温室气体浓度。 快速气候变化（RAPID）计划是自然环境研究委员会资助的、总投入2000万英镑、为期六年（2001-2007）的研究项目。该计划旨在提升对未来气候快速变化的概率与强度进行量化评估的能力，核心（但非唯一）研究焦点为大西洋温盐环流的作用。
