Evolution of Asian monsoons and phased uplift of the Himalaya–Tibetan plateau since Late Miocene times
TLDR
The results of a numerical climate-model experiment support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciation.Abstract:
The climates of Asia are affected significantly by the extent and height of the Himalayan mountains and the Tibetan plateau1,2,3,4 Uplift of this region began about 50 Myr ago, and further significant increases in altitude of the Tibetan plateau are thought to have occurred about 10–8 Myr ago4,5, or more recently However, the climatic consequences of this uplift remain unclear Here we use records of aeolian sediments from China6,7 and marine sediments from the Indian8,9,10 and North Pacific oceans11 to identify three stages of evolution of Asian climates: first, enhanced aridity in the Asian interior and onset of the Indian and east Asian monsoons, about 9–8 Myr ago; next, continued intensification of the east Asian summer and winter monsoons, together with increased dust transport to the North Pacific Ocean11, about 36–26 Myr ago; and last, increased variability and possible weakening of the Indian and east Asian summer monsoons and continued strengthening of the east Asian winter monsoon since about 26 Myr ago The results of a numerical climate-model experiment, using idealized stepwise increases of mountain–plateau elevation, support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciationread more

A Simulated Climatology of Asian Dust Aerosol and Its Trans-Pacific Transport. Part II: Interannual Variability and Climate Connections
Sunling Gong,Xiaoye Zhang,T. L. Zhao,Xuebin Zhang,Leonard A. Barrie,Ian G. McKendry,C. S. Zhao +6 more
TL;DR: A 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960-2003 was simulated with the Northern Aerosol Regional Climate Model (NARCM) as discussed by the authors.

Mechanisms Limiting the Northward Extent of the Northern Summer Monsoons over North America, Asia, and Africa*
Chia Chou,J. David Neelin +1 more
TL;DR: In this paper, the authors examined the poleward extent of summer monsoon convergence zones for North America, Asia, and Africa in an intermediate atmospheric model coupled with a simple land model and a mixed layer ocean.

Molecular phylogeny of the tribe Bovini (Bovidae, Bovinae) and the taxonomic status of the Kouprey, Bos sauveli Urbain 1937.
Alexandre Hassanin,Anne Ropiquet +1 more
TL;DR: A molecular phylogeny of the tribe Bovini is performed to determine the taxonomic status of the kouprey and shows that it belongs to the subtribe Bovina, and that three different clades can be evidenced into this group.

On the interpretation of Chinese loess as a paleoclimate indicator
TL;DR: In this article, it was shown that dust outbreaks in Asia are predominantly springtime phenomena, and that frequent cyclogenesis in the lee of the Mongolian Altai and the passage of strong cold fronts produce the intense windstorms that loft and entrain dust into the air.

Grain size of loess；palaeosol and Red Clay deposits on the Chinese Loess Plateau: Significance for understanding pedogenic alteration and palaeomonsoon evolution
TL;DR: In this paper, the relative intensity of pedogenic alteration of the loess, palaeosol and Red Clay deposits can be quantified by comparing the grain size distributions and contents of different grain size fractions between the bulk and the quartz samples.

Global vegetation change through the Miocene/Pliocene boundary
Thure E. Cerling,John Harris,Bruce J. MacFadden,Meave G. Leakey,Jay Quade,Véra Eisenmann,James R. Ehleringer +6 more
TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.

Mantle dynamics, uplift of the Tibetan Plateau, and the Indian Monsoon
TL;DR: For example, Hou et al. as mentioned in this paper show that a small increase in the mean elevation of the Tibetan Plateau of 1000 m or more in a few million years is required by abrupt tectonic and environmental changes in Asia and the Indian Ocean.

Surface Deformation and Lower Crustal Flow in Eastern Tibet
Leigh H. Royden,B. Clark Burchfiel,Robert W. King,Erchie Wang,Zhiliang Chen,Feng Shen,Y. Liu +6 more
TL;DR: This model predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.

Correlation between climate events in the North Atlantic and China during the last glaciation
TL;DR: The authors examined grain-size data from Chinese loess and intercalated accretionary palaeosols of last-glacial age for evidence of similar climate signals remote from the North Atlantic region.

Finite strain calculations of continental deformation .2. comparison with the india-asia collision zone
TL;DR: In this article, a thin viscous sheet model for deformation of continental lithosphere subjected to an indenting boundary condition yield distributions of crustal thickness, of stress and strain rate, and of latitudinal displacements that may be compared with observations in the India-Asia collision zone.
