Coupled ocean and atmospheric changes during Greenland stadial 1 in southwestern Europe

Hydroclimatic changes in the British Isles through the Last-Glacial-Interglacial Transition: Multiproxy reconstructions from the Vale of Pickering, NE England

“…Changes in hydroclimatic signals through GS-1 (including the Younger Dryas in Europe) are more complex than those in GI-1d and GI-1b, and have also been attributed to the position of the NAPF across the European continent (e.g. Brauer et al, 2008;Bakke et al, 2009;Lane et al, 2013;Rach et al, 2014;Naughton et al, 2019). The findings presented here broadly supports these interpretations (i.e.…”

“…Collectively, the regional comparisons discussed above support that during the abrupt climatic events of the LGIT, winter sea-ice expansion in the North Atlantic initiated a southerly migration of the NAPF (e.g. Denton et al, 2005;Renssen et al, 2018;Muschitiello et al, 2019;Naughton et al, 2019), the focussing of stronger and more zonal westerly winds devoid of moisture across Northern Europe (Brauer et al, 2008), and the depression of moisture bearing subpolar cyclonic activity into Central and Southern Europe (e.g. Marchal et al, 2016;Pauly et al, 2018).…”

The deglaciation of the Americas during the Last Glacial Termination

“…Fogwill et al (2017) argue that, once deglaciation starts, it is driven by global oceanic and atmospheric teleconnections. New data support J o u r n a l P r e -p r o o f the idea that meltwater cooling of the Northern Hemisphere reduced the AMOC strength (Deaney et al, 2017;Muschitiello et al, 2019) and pushed the northern westerlies southward in Asia (Chen et al, 2019), Europe (Naughton et al, 2019), and North America (Hudson et al, 2019). The Asian summer monsoon weakened during these cold periods in the Northern Hemisphere (Cheng et al, 2016;Chen et al, 2019), and the Indian summer monsoon transferred Southern Hemisphere heat northward, promoting subsequent Northern Hemisphere deglaciation (Nilsson-Kerr et al, 2019).…”

“…Undoubtedly, it is the most widely studied deglacial period. Although climate varied extraordinarily during this period (Naughton et al, 2019), its effects in the Northern Hemisphere are clearthe AMOC weakened (Meissner, 2007;Muschitiello et al, 2019), sea ice expanded, and winter and spring temperatures dropped drastically (Steffensen et al, 2008;Mangerud et al, 2016); summers remained relatively warm (Schenk et al, 2018). Glaciers in Europe advanced (Ivy-Ochs, 2015;Mangerud et al, 2016), and the Asian monsoon weakened (Wang et al, 2008).…”

“…The causes of the abrupt YD anomaly continue to be a topic of debate. Changes in deep-water circulation in the Nordic seas, weakening of the AMOC (Muschitiello et al, 2019), moderate negative radiative forcing and altered atmospheric circulation (Renseen et al, 2015;Naughton et al, 2019) likely played a role.
