“…Further south, oxygen-isotope-based estimates of palaeoaltitude from late Eocene-Oligocene formations in the Lunpola Basin in central Tibet indicate that the central Tibetan Plateau has been characterized by elevations in excess of 4 km since 35 ± 5 Ma (Rowley and Currie, 2006). Also, Song et al (2010) recently suggested, based on pollen, that altitudes for Eocene central-southern Tibet were a minimum of 3295-3495 m. Altogether this indicates that elevated topography extended away from the collision zone very early after initial collision such that an early plateau formation may have already contributed to monsoon intensification together with Paratethys sea retreat (Ramstein et al, 1997;Zhang et al, 2007).…”

“…Climate models show that uplift of the Tibetan Plateau and the redistribution of land and sea, associated with the continentcontinent collision of India and Asia, caused continental aridification and intensification of the monsoons (Ramstein et al, 1997;Boos and Kuang, 2010). As a result, paleoenvironmental records have invariably associated Tibetan and Himalayan uplift with evidence for aridification north of the Tibetan Plateau and monsoon intensification to the south (e.g.…”

Climate models suggest that Asian paleoenvironments, monsoons and continental aridification were primarily governed by tectonic uplift and sea retreat since the Eocene with potential contribution of global climate changes. However, the cause and timing of these paleoenvironmental changes remain poorly constrained. The recently well-dated continental mudflat to ephemeral saline lake sedimentary succession, situated in the Xining Basin at the northeastern margin of the Tibetan Plateau (NW China), provides a unique opportunity to develop additional proxy successions in this area that are placed accurately in time. Here, a palynological record from this succession is reported. High abundances of desert and steppe-desert taxa such as Ephedripites and Nitrariadites/Nitraripollis are found, which can be differentiated by the presence of broad leaved deciduous forest taxa in the lower part of the section (particularly up to 36.4 Ma; magnetochron C16r), and a sudden increase of Pinaceae (Pinuspollenites, Piceaepollenites and Abiespollenites) which is dated at 36.1 Ma (C16n.2n). Coexistence Approach (CoA) indicates that from 39.9 to 36.4 Ma (C17n.1n) regional climate was warm and wet, while from 36.4 to 33.5 Ma (C16n.2n-C13r) climate tends to be cooler and drier. The data indicate that paleoenvironmental and palynological changes on the NE part of the Tibetan Plateau resulted from a combination of long-term tectonic uplift forcing and long-and short-term climate changes. The increase of taxa such as Piceaepollenites and Abiespollenites indicates not only a cooling and drying trend prior to the Eocene/Oligocene (E/O) boundary, but also the existence of high altitude mountain habitats in the periphery of the Xining Basin. The sudden Pinaceae event correlates closely in time with a marked aridification step as viewed from the lithology of the Xining Basin that was linked to the sea retreat out of the Tarim Basin.

“…Some numerical experiments indicated that changes in the distribution of land and sea had strong influence on the Asian monsoon. For example, the expansion of the Eurasian continent due to the retreat of the Paratethys Sea could also lead to an increase in the Asian monsoon precipitation and intensified inland aridification [59,60]. The experiment without the Australian continent showed that the Australian anticyclone and the southeast monsoon in its northern side was weakened significantly, and the Mascarene anticyclone and the southeast monsoon to its north was affected and weakened as well [82].…”

“…For example, in the climate simulation of the Eocene (45-33 Ma) [58], the maximum height of the TP was set at 2000-4000 m and corresponding average topographic height was set at about only 750-1500 m. This simulation revealed remarkable impacts of the TP topographic change on its neighboring regional climate, but also demonstrated that the plateau topographic reduction during the Eocene had limited impacts on the existing global monsoon and precipitation at that time. Ramstein et al [59] simulated the climate in the early Oligocene (~30 Ma) when the Paratethys Sea occupied many areas of western Asia to central Asia while limited uplift occurred only in the southern TP. Their results showed that the expansion of Eurasian land area with the retreat of the Paratethys Sea from the early Oligocene to the late Miocene significantly enhanced the Asian monsoon and precipitation.…”

Influence of the Tibetan Plateau uplift on the Asian monsoon-arid environment evolution

2013

As one of the most important geological events in Cenozoic era, the uplift of the Tibetan Plateau (TP) has had profound influences on the Asian and global climate and environment evolution. During the past four decades, many scholars from China and abroad have studied climatic and environmental effects of the TP uplift by using a variety of geological records and paleoclimate numerical simulations. The existing research results enrich our understanding of the mechanisms of Asian monsoon changes and interior aridification, but so far there are still a lot of issues that need to be thought deeply and investigated further. This paper attempts to review the research on the influence of the TP uplift on the Asian monsoon-arid environment, summarize three types of numerical simulations including bulk-plateau uplift, phased uplift and sub-regional uplift, and especially to analyze regional differences in responses of climate and environment to different forms of tectonic uplifts. From previous modeling results, the land-sea distribution and the Himalayan uplift may have a large effect in the establishment and development of the South Asian monsoon. However, the formation and evolution of the monsoon in northern East Asia, the intensified dryness north of the TP and enhanced Asian dust cycle may be more closely related to the uplift of the main body, especially the northern part of the TP. In this review, we also discuss relative roles of the TP uplift and other impact factors, origins of the South Asian monsoon and East Asian monsoon, feedback effects and nonlinear responses of climatic and environmental changes to the plateau uplift. Finally, we make comparisons between numerical simulations and geological records, discuss their uncertainties, and highlight some problems worthy of further studying.Tibetan Plateau, tectonic uplift, Asian monsoon, inland aridity, environmental evolution, geological record, numerical simulation Citation:Liu X D, Dong B W.

A modeling study of the response of Asian summertime climate to the largest geologic forcings of the past 50 Ma

The modern Asian summer monsoon is known to be affected by the modern continental geometry, orography, atmospheric composition, interglacial climate state, and orbital configuration. All of these factors, however, have undergone substantial changes since the Indian and Asian continents collided 50 million years ago. Within the framework of one general circulation model we evaluate the relative importance of each of these factors for the spatial patterns of summertime climate fields and precipitation-weighted 18 O. We find that the continental-scale structure of the monsoon circulation remains robust, but there are important impacts on local environmental conditions. The largest differences in climate are associated with changes in orbital configuration and topography because of how those factors influence local gradients in the summer climate variables. Finally, model calculations are consistent with the modern understanding of monsoon dynamics in which the strength of the circulation and the distribution of rainfall are tightly coupled to the spatial patterns of low-level moist static energy and upper tropospheric temperature.
