本文利用群落气候系统模式第4版（CCSM4）和马克斯·普朗克气象研究所古气候模式（MPI-ESM-P）两个气候模式的近千年（LM）和历史实验（850-2005 AD）和控制（CTL）实验的结果，分析了El Niño-Southern涛动（ENSO）和北大西洋涛动（NAO）的十年-百年变化。重点分析了中世纪暖期（MWP, 1050-1150 AD）、小冰期（LIA, 1600-1700 AD）和20世纪变暖期（20CW, 1905-2005 AD） ENSO和NAO的变化。在ENSO和NAO系列中分别检测到重要的双百年周期和多年代际周期。两种模式对三个典型时期的ENSO和NAO相进行了统计上显著的对比。捕获了MWP期间El Niño-like状态、LIA期间La Niña-like状态和20CW期间El Niño-like状态的与模型无关的转换。然而，NAO系列表现出模型依赖性。CCSM4在小冰期表现为负相NAO， MPI-ESM-P在小冰期表现为正相NAO。ENSO和NAO相的变化主要是由太阳-火山（SV）强迫和温室气体（GHG）强迫引起的。
The decadal–centennial variations of the El Niño–Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO) are analyzed, based on the outputs of last millennium (LM) and Historical experiments (850–2005 AD) and control (CTL) experiments from two climate models Community Climate System Model, version 4 (CCSM4) and Max Planck Institute for Meteorology Paleoclimate Model (MPI-ESM-P). Variation of ENSO and NAO among the Medieval Warm Period (MWP, 1050–1150 AD), Little Ice Age (LIA, 1600–1700 AD) and 20th Century Warming (20CW, 1905–2005 AD) are focused. Significant bi-centennial and multi-decadal periods are detected in the ENSO and NAO series, respectively. Both models have exerted statistically-significant contrasts of ENSO and NAO phases among the three typical periods. The model-independent shifts of an El Niño-like state during the MWP, a La Niña-like state during the LIA and an El Niño-like state during the 20CW are captured. However, the NAO series display a model-dependence. CCSM4 features a negative-phased NAO during the LIA, while MPI-ESM-P is characterized by a positive-phased NAO in the same period. The shifts of the ENSO and NAO phases are mainly due to the external radiative forcing, including the solar-volcanic (SV) forcing and greenhouse gases (GHG) forcing.
