It affects terrestrial ecosystems in China because of its unique location, high elevation (topography), and special climate systems . The Tibetan Plateau covers approximately 25 percent of China’s surface area, spreading out over 2.5 million sq. To assess the effects of the rise of the Himalayas and the Tibetan Plateau on climate, the team used a computer model of world climate to show that the mountain and plateau uplift enhanced both the winter and summer Asian monsoons and gave rise to a drying trend in central Asia. This paper reviews progress in the study of Tibetan Plateau (TP) climate dynamics over the past decade. This synthesis report summarises over 150 recent research reports published in scientific journals, by Chinese and international scientists, all fully referenced. Climate Low of TCO Over the Tibetan Plateau [7] Figure 1a is the longitude‐latitude cross section of (λ,φ, m ) y in May with a contour interval of 10 Dobson units (DU, 1 DU = 0.01 cm at standard temperature and atmospheric pressure (273.16 K and 1 atm)). The Tibetan Plateau exerts a major influence on Asian climate, but its long-term environmental history remains largely unknown. Keywords: Tibetan Plateau, climate change, cryosphere 1. Tibetan Plateau snow cover (TPSC) is a key component of the climate sys-tem. Botsyun et al. The Tibetan Plateau is the highest plateau in the world and is known as the “third pole”. Food security, energy production and health security are also severely threatened by climate change. The biomes on the Tibetan Plateau are special . Tibetan Plateau snow cover (TPSC) is a key component of the climate system. Due to its high elevation and cold climate, the Tibetan Plateau has much more snow cover than the other regions at the same latitude. Several theoretical frameworks, including thermal adaptation and the TP sensible heat (SH) driving air-pump, have been developed to identify the mechanisms responsible for the circulation anomaly produced by thermal forcing of the TP. The Tibetan Plateau once hosted a "Shangri-La"-like ecosystem -- wet, warm and rich in biodiversity. Phenological responses of vegetation to climate, in particular to the ongoing warming trend, have received much attention. Due to the complex of its topography, the climate of different areas of the plateau is not the same. However, divergent results from the analyses of remote sensing data have been obtained for the Tibetan Plateau (TP), the world’s largest high-elevation region. Source: Xinhua | 00:00 UTC+8 December 8, 2020 | Print Edition. Environmental conditions on the Tibetan Plateau (TP) during the last glacial maximum (LGM) are poorly known. aspects of climate change on the Tibetan Plateau. Introduction The Tibetan Plateau (TP), with an average elevation of over 4000 m asl and an area of approximately 2.5 ×106 km2,isthe 6 Author to whom any correspondence should be addressed. The mesoscale topography over the TP plays an important role in generating and enhancing mesoscale disturbances. Tibetan Plateau, represented by glaciers retreating and lakes expanding, but the biological response to climate change by plateau–lake ecosystems is poorly known. The Tibetan Plateau is one of the world’s most pristine ecological regions. In this paper, we evaluate the ability of 22 GCMs to reproduce temperature and precipitation over the Tibetan Plateau by comparing with ground observations for … Experiments with reduced height over the Tibetan Plateau and the Himalayas have been designed. Knowing local Tibetans’ perceptions of climate and ecological changes is important for exploring the climate and vegetation changes in this vast and remote plateau. Progress in observation experiments and studies concerning the effects of the Tibetan Plateau (TP) on weather and climate during the last 5 years are reviewed. It is home to the largest store of freshwater outside of the North and South Poles, feeding water into Asia’s major rivers which supply water to over a billion people. The Tibetan Plateau (TP) is an ecologically fragile region that is sensitive to climate change. Everest. Mesoscale Tibetan Plateau vortices (TPVs) are one of the major precipitation-producing systems on the TP. Tibetan Plateau: Definition, Location, Formation, and Interesting Facts. Learn more about climate of Mt. Glacial melt in the Himalayas presents a severe threat to long-term water security, affecting some 1.5 billion people on the Plateau and in downstream states. The Tibetan Plateau is highly sensitive to climate change. Although some isotope proxies have suggested a roughly equivalent height for the plateau as far back as the Eocene (∼40 million years ago), other lines of evidence suggest a lower elevation in the distant past. Zhengguo Shi, Yingying Sha, Xiaodong Liu, Xiaoning Xie, Xinzhou Li Effect of marginal topography around the Tibetan Plateau on the evolution of central Asian arid climate: Yunnan–Guizhou and Mongolian Plateaux as examples, Climate Dynamics 53, no.7-8 7-8 (May 2019): 4433–4445. Existing studies of environmental proxies and climate model simulations are contradictory, with interpretations varying between cold-dry and cold-wet environmental conditions which differentially influenced lake volumes, loess deposition and vegetation communities across the TP. The Tibetan Plateau (TP), with an average elevation of over 4000 m asl and an area of approximately 2.5 × 10 6 km 2, is the highest and most extensive highland in the world.Referred to as the 'Third Pole', the TP exerts a huge influence on regional and global climate through thermal forcing mechanisms (Duan and Wu 2005, Yanai et al 1992, Yeh and Gao 1979). A fraction of TPVs move off the TP to the east and can … Regional setting Climate and vegetation of the Tibetan Plateau The Tibetan Plateau, with an average altitude of more than 4000 m asl, is situated in the western part of China between 80– 105°E and 27–37°N. The Qinghai-Tibet Plateau is the largest high-elevation part of the cryosphere outside the polar regions, with vast areas of mountain glaciers, … Our results show that the isotopic composition of precipitation is very sensitive to climate changes related to the growth of the Himalayas and Tibetan Plateau. Conroy and Overpeck (2011) divided the modern climate in the Tibetan Plateau region into three areas of distinct precipitation variability based on empirical orthogonal function analysis. In the context of global climate change, the climate change trends of the TP and the vegetation dynamic response need to be investigated. km in the west of the country. The southeast Tibetan Plateau (SETP), together with its vicinity, is one of the most studied areas in China with a network of relatively densely distributed tree-ring chronologies developed from endemic tree species. A Chinese institute has launched a dataset for hourly observations of integrated land-atmosphere interaction on the Qinghai-Tibet Plateau. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4) presents twenty-two global climate models (GCMs). Qinghai-Tibet Plateau climate study. The Tibetan Plateau, with an average altitude of about 5000 m, is one of the most important regions in the world. The date of the first permanent human occupation of the high Tibetan Plateau has been estimated at about 3600 years ago, when agriculture became established. Human life and the entire ecosystem of South East Asia depend upon the monsoon climate, its linkage to major rivers and its predictability. The Tibetan Plateau (TP) and surrounding high mountains constitute an important forcing of the atmospheric circulation due to their height and extent, and thereby impact weather and climate in downstream regions of East Asia. Climate change is sometimes discussed as a problem of the future, but on the "roof of the world", it has already arrived. Complex climate-growth relationships in the SETP are largely due to its large climate gradients and complex topographic features. Generally, there is less rain on the plateau. Meyer et al. 7 October 2020. Their analysis indicates occupation of the plateau 7400 years ago and possibly earlier. Tibetan Plateau will help to track regional differences in climate history in Central Asia and to understand its causes. Huanghe Gu, Zhongbo Yu, W. Richard Peltier, Xiaoyan Wang, Sensitivity studies and comprehensive evaluation of RegCM4.6.1 high-resolution climate simulations over the Tibetan Plateau, Climate Dynamics, 10.1007/s00382-020-05205-6, (2020). highest and most extensive highland in the world.
