Abstract Forcings and mechanisms underlying Holocene climate variability still remain poorly. This work review already published paleoclimatic time series and proposes an alternative way to compare them using spectral analysis. Such an approach may emphasize joint features between different signals and lead us closer to the causes of climate changes. Ten paleoclimatic proxy records from 5 sequences from the Gulf of Lions and surrounding areas were compiled. These paleoclimate time-series were supplemented with proxies of the North Atlantic Oscillations (NAO), El Nino–Southern Oscillations (ENSO) and the Intertropical Convergence Zone (ITCZ) variability. A comparison of their frequency content is proposed using wavelet analysis for unevenly sampled time series. A new algorithm is used in order to propagate the age model errors within wavelet power spectra. Three main groups of shared features specific to the Mid- and Late Holocene (after 7000 yrs cal BP) can be defined on the basis of the results of these analyses, an Atlantic cyclic period, solar cyclic periods and tropical cyclic periods. The Atlantic cyclic period is probably related to fluctuations of the Atlantic thermohaline circulation which would induce changes in the storm track extension and position thereby impacting upon precipitation and storminess over a millennial scale. The centennial scale solar variability might induce a NAO-like variability of the atmospheric circulation thereby influencing storminess in Western Europe and Mediterranean. Finally, tropical cyclic periods are possibly registered in of the Gulf of Lions and Atlantic climate proxies, potentially highlighting the influence of ENSO variability over the western Mediterranean.

中晚期全新世地中海气候变异：使用小波分析在地中海西北部盆地进行多代理和多序列比较的贡献

摘要 全新世气候变率背后的强迫和机制仍然薄弱。这项工作回顾已经发表了古气候时间序列，并提出了一种使用光谱分析比较它们的替代方法。这种方法可能会强调不同信号之间的共同特征，并使我们更接近气候变化的原因。汇集了来自狮子湾及周边地区的 5 个序列的 10 个古气候代理记录。这些古气候时间序列补充了北大西洋涛动 (NAO)、厄尔尼诺-南方涛动 (ENSO) 和热带辐合带 (ITCZ) 变率的代表。对于不均匀采样的时间序列，建议使用小波分析来比较它们的频率内容。为了在小波功率谱内传播年龄模型误差，使用了一种新算法。根据这些分析的结果，可以定义三组特定于全新世中晚期（7000 年之后）的主要共有特征，即大西洋周期、太阳周期和热带周期。大西洋循环周期可能与大西洋温盐环流的波动有关，这会引起风暴轨迹延伸和位置的变化，从而影响千年尺度的降水和风暴。百年尺度的太阳变化可能会导致大气环流类似 NAO 的变化，从而影响西欧和地中海的暴风雨。最后，
