                      influences of Southern Hemispheric Westerlies (SHW) on the
                      hydroclimatic variability of south-eastern Patagonia. During
                      the last 4000 years, this hydroclimatic variability is
                      overprinted by centennial warm/dry periods. A cool/wet
                      period from 11,600 to 10,100 cal. BP is succeeded by an
                      early Holocene dry period (10,100–8300 cal. BP) with a
                      shallow lake, strong anoxia, methanogenesis and high
                      salinity. Between 8300 and 4000 cal. BP the influence of SHW
                      weakened, resulting in a freshwater lake considered to be
                      related to less arid conditions. Since 4000 cal. BP,
                      regional temperature decreased accompanied by
                      re-intensification of SHW reaching full strength since 3000
                      cal. BP. Centred around 2200, 1000 cal. BP and in the 20th
                      century, Laguna Azul experienced century-long warm/dry
                      spells. Between these dry periods, two pronounced moist
                      periods are suggested to be contemporaneous to the ‘Dark
                      Age Cold Period’ and the ‘Little Ice Age’. Different
                      from millennial SHW variations, centennial fluctuations
                      appear to be synchronous for South America and the Northern
                      Hemisphere. Changes in solar activity, large volcanic
                      eruptions and/or modulations of ocean circulation are
                      potential triggers for this synchronicity.},
