RAPID Improving our Ability to Predict Rapid Changes in the El Nino Southern Oscillation Climatic Phenomenon: HADCM3 model output

"Improving our ability to predict rapid changes in the El Nino Southern Oscillation climatic phenomenon" project, which was a Natural Environment Research Council (NERC) RAPID Climate Change Research Programme project (Round 1 - NER/T/S/2002/00443 - Duration 1 Jan 2004 - 30 Sep 2007) led by Prof Alexander Tudhope of the University of Edinburgh, with co-investigators at the Scottish Universities Environment Research Centre, Bigelow Laboratory for Ocean Sciences, and the University of Reading.

This dataset collection contains HadCM3 model outputs.

The objective was to use a combination of palaeoclimate reconstruction from annually-banded corals and the fully coupled HadCM3 atmosphere-ocean general circulation model to develop an understanding of the controls on variability in the strength and frequency of ENSO, and to improve our ability to predict the likelihood of future rapid changes in this important element of the climate system. To achieve this, three periods were targeted:

a) 0-2.5 ka: Representative of near-modern climate forcing; revealing the internal variability in the system.
b) 6-9 ka: a period of weak or absent ENSO, and different orbital forcing; a test of the model's ability to capture externally-forced change in ENSO.
c) 200-2100 AD: by using the palaeo periods to test and optimise model parameterisation, produce a new, improved, prediction of ENSO variability in a warming world.

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.

提升对厄尔尼诺南方涛动气候现象快速变化的预测能力项目，该项目为英国自然环境研究委员会（Natural Environment Research Council，NERC）的快速气候变化研究计划项目（RAPID Climate Change Research Programme，第一轮 - NER/T/S/2002/00443 - 持续时间：2004年1月1日至2007年9月30日），由爱丁堡大学亚历山大·塔德霍普（Alexander Tudhope）教授领导，联合调查员来自苏格兰大学环境研究中心、比格洛海洋科学实验室和雷丁大学。本数据集收集包含HadCM3模型输出。

项目目标是通过结合年带珊瑚的古代气候重建和完全耦合的HadCM3大气-海洋一般环流模型，以深入理解厄尔尼诺南方涛动（ENSO）强度和频率变化的影响因素，并提升预测气候系统中这一重要元素未来快速变化可能性的能力。为实现此目标，项目针对以下三个时期进行研究：

a) 0-2.5千年前：代表近现代气候强迫；揭示系统内部的变率。

b) 6-9千年前：一个弱或无ENSO的时期，以及不同的轨道强迫；检验模型捕捉外部强迫变化在ENSO中的作用。

c) 200-2100年：利用古代时期测试和优化模型参数化，在一个变暖的世界中，对ENSO变率进行新的、改进的预测。

快速气候变化（RAPID）项目是英国自然环境研究委员会（Natural Environment Research Council）一项耗资2000万英镑、为期六年（2001-2007年）的计划。该计划旨在提升量化未来气候变化快速变化的概率和幅度的能力，主要（但非唯一）关注大西洋海洋热盐环流的作用。
