| Summary: | Climatic outputs of a transient deglacial simulation performed with LOVECLIM (Goosse et al., 2010) with ICE5G (Peltier, 2004) forcing. The experiment is similar to Menviel et al., 2011, but the greenhouse gases and ice-sheet forcings are updated and the meltwater forcing is slightly different. This experiment starts from the experiment that does not include a Southern Ocean meltwater pulse at 14.8ka. This experiment includes meltwater in the Southern Ocean during the ACR. The results of this experiment are discussed in Obase et al., 2024 and Snoll et al., 2024. ... : From 21ka, LOVECLIM is forced by the transient evolution of orbital parameters (Berger, 1978), greenhouse gases (Kohler et al., 2017), ice-sheet extent, orography and albedo (Peltier, 2004) as well as idealised meltwater input in the North Atlantic following the TRACE 21 experiment. The North Atlantic (50N-61N, 60W-3W) meltwater pulse was added from 17 to 14.67 ka at a constant rate of 0.1721 Sv (equivalent to 35m sle), and between 12.8 and 11.8 ka at 0.1124 Sv. The Southern Ocean meltwater was added between 14.67 ka to 14.1 ka at a constant 0.2 Sv (total sle of 10m), between the Ross Sea and Weddell Sea (81S-67S, 160W-10E, i.e. an ocean area of 6.484 10^12 m2). ... |
