Orographic evolution of northern Tibet shaped vegetation and plant diversity in eastern Asia

“…Numerical modeling is a powerful tool for exploring links between long-term orogenesis, climate change, and associated vegetation dynamics. However, classic climate sensitivity simulations treat Tibet as a single geological unit with no spatial complexity changing its height against a background of present-or paleogeography (14)(15)(16)(17). Some studies have simulated complex regional uplift histories (10,18), but very few modeling studies have directly examined the impact of Tibetan development on vegetation (19,20) and none on biodiversity.…”

Monsoon‐Enhanced Silicate Weathering as a New Atmospheric CO2 Consumption Mechanism Contributing to Fast Late Miocene Global Cooling

“…This uplift‐induced EASM enhancement is mainly caused by the surface sensible heating of the northern and central TP that can induce a low‐level cyclonic anomaly around the TP, thus strengthening the northward advance of warm advection from the south of the TP (Tang et al., 2013). The dominance of the uplift of the TP on the formation of a modern‐like climate regime in East Asia is also supported by a recent climate modeling study (Zoura et al., 2019), which highlighted that the primary control on the Asian hydroclimate is the topography of the TP rather than CO 2 changes and ice sheet formation, although the latter two factors are also important (R. Zhang et al., 2018). Thus, the increases in the SWI in the HLD and ZL sections at ∼9–7 Ma suggest a significant uplift‐forced intensification of the EASM (Figure 5)…”

“…In principle, the primary factors controlling late Miocene development of the East Asian monsoon climate are global cooling (e.g., Miao et al., 2011), Antarctic glaciation (Ao et al., 2016) and the tectonic uplift of the TP (e.g., An et al., 2001; Tada et al., 2016; Zoura et al., 2019), especially the rise and growth of the northern TP, as revealed by climate models (e.g., An et al., 2001; Tada et al., 2016; R. Zhang et al., 2012). The driving force of the significantly enhanced EASM is unlikely to be global cooling, which should have weakened the SWI.…”

“…The late Miocene evolution of the East Asian monsoon climate was assumed to be primarily driven by global cooling, Antarctic glaciation, and the tectonic uplift of the TP (e.g., An et al., 2001; Ao et al., 2016; Clift et al., 2014; Miao et al., 2011; Tada et al., 2016; Zoura et al., 2019). Thus, the East Asian monsoon region provides an ideal case for revealing intriguing and complex tectonic‐climate interactions.…”

Effects of Tibetan Plateau Growth, Paratethys Sea Retreat and Global Cooling on the East Asian Climate by the Early Miocene

“…Climate modeling is a useful tool for exploring the links between these factors and climate change. Previous modeling studies have shown that uplift, extension and northward motion of the TP markedly changed East Asian atmospheric circulation and precipitation by affecting the land‐sea thermal contrast and pressure gradient (e.g., An et al., 2001; Botsyun et al., 2019; Chakraborty et al., 2002; Farnsworth et al., 2019; Jiang et al., 2008; Kutzbach et al., 1989; S. F. Li et al., 2021; Liu & Yin, 2002; Roe et al., 2016; Zhang, Jiang, Ramstein et al., 2018; Z. Zhang et al., 2007; Zoura et al., 2019, 2020). The retreat of the Paratethys Sea is also believed to have been an important factor associated with the changing humidity in East Asia and inland Asia by affecting the pressure system and atmospheric circulation (e.g., S. F. Li et al., 2018; Ramstein et al., 1997; Z. Zhang et al., 2007).…”
