由志愿者捐赠的计算资源已经产生了第一个区域气候模式结果的超级集合,其中Hadley中心区域模式版本3P(HadRM3P)和Hadley中心大气模式版本3P(HadAM3P)在美国西部以25公里的分辨率实施。到目前为止,已经产生了超过136,000次有效和完整的一年运行:1960-2009年约有126,000次使用观测到的海表面温度(SSTs),2030-49年约有10,000次使用全球模式模拟预测的SSTs。合奏成员在初始条件、模型物理和(可能在未来运行)SST方面有所不同。这种史无前例的高空间分辨率和大集合尺寸的融合允许高信噪比和更稳健的不确定性估计。本文描述了这个实验,比较了模式输出和观测结果,展示了气候变化模拟的精选结果,并给出了大集合强度的例子。
AbstractComputing resources donated by volunteers have generated the first superensemble of regional climate model results, in which the Hadley Centre Regional Model, version 3P (HadRM3P), and Hadley Centre Atmosphere Model, version 3P (HadAM3P), were implemented for the western United States at 25-km resolution. Over 136,000 valid and complete 1-yr runs have been generated to date: about 126,000 for 1960–2009 using observed sea surface temperatures (SSTs) and 10,000 for 2030–49 using projected SSTs from a global model simulation. Ensemble members differ in initial conditions, model physics, and (potentially, for future runs) SSTs. This unprecedented confluence of high spatial resolution and large ensemble size allows high signal-to-noise ratio and more robust estimates of uncertainty. This paper describes the experiment, compares model output with observations, shows select results for climate change simulations, and gives examples of the strength of the large ensemble size.
