Model evidence for climatic impact of thermohaline circulation on China at the century scale

Abstract

Based on transient simulation of the last deglaciation (significant global warming period) using a fully coupled model and sensitivity experiment, we show explicitly how the thermohaline circulation (THC) affects the climate of China, especially during periods of abrupt climate change. The simulated evolution of the Chinese climate was consistent with the paleoclimate record during the last deglaciation. For example, the whole Chinese region warmed significantly during the Bølling-Allerød warming event (BA). When the magnitude of the THC was reduced in the sensitivity experiment during BA, warming of the Chinese region was greatly affected. Our work shows that in addition to orbital forcing and greenhouse gases, the THC is an important factor influencing climate change in China at the century scale. thermohaline circulation, China, model simulation, climate change, partial Blocking scheme, Bølling-Allerød warming event, Hulu Cave Citation: Cheng J, Liu Z Y, He F, et al.

Simulation of sea surface temperature changes in the Middle Pliocene warm period and comparison with reconstructions

“…Over the past two decades, many geological studies have presented results on different time scales through reconstruction [1][2][3][4][5][6][7]. In terms of modeling, on the other hand, some progress has been made in understanding the mechanisms of past climate changes [8][9][10][11][12][13][14][15][16], but most modeling studies have focused on the Quaternary climate and little attention has been given to warm periods before the Quaternary.…”
