“…During the past 50 years, the warming abnormality of the Plateau has exceeded the average value of the north hemisphere and corresponding regions with the similar latitude. It has been deemed to be a driver and an enlarger for the global climate change (Pan and Li 1996;Feng et al 1998).…”

Through analyzing the changes of averaged temperature and precipitation along the Brahmaputra Valley from 1980 to 2005, and investigating the correlation between atmospheric circulation indices and these changes, the respondence of the Brahmaputra Valley to the global warming had been analyzed in this paper. It is found that the Brahmaputra Valley climate became warmer and wetter from 1980 to 2005, and the change magnitude is higher than that over the whole Tibetan Plateau. Therefore, the respondence of the Brahmaputra Valley to the global warming is more evident than that of the whole plateau during the period. The relationship between atmospheric circulation indices and the regional climate change is significant. When North Atlantic Oscillation index is higher in summer, the climate of the Brahmaputra Valley becomes warmer and dryer; vice versa. When South Oscillation index is higher, it becomes warmer and wetter; vice versa. Worthy of note, the results in this study only emphasize some evidence of change in temperature and precipitation over the Brahmaputra Valley during 1980Valley during -2005

“…As one of the most active regions with respect to global climate change, the Qinghai-Tibetan Plateau (QTP) is a powerful "engine" that can start or regulate certain types of climate change [1,2]. The QTP is a giant tectonic geomorphic unit, at the highest altitude on Earth, and has a unique natural environment that follows a special differentiation law.…”

“…In the past few decades, with global warming, the annual temperature (T a ) significantly increased over the TP (Karl et al, 1993;David et al, 1997;Feng et al, 1998;Wei et al, 2003;Oku et al, 2006).…”

In this paper, the possible reason of Tibetan Plateau (TP) temperature increasing was investigated. An increase in Tmin (minimum temperature) plays a robust role in increased TP temperature, which is strongly related to SST over the warm pool of the western Pacific Ocean, the subtropical westerly jet stream (SWJ), and the tropical easterly upper jet stream (TEJ), and the 200-hPa zonal wind in East Asia. Composite analysis of the effects of SST, SWJ, and TEJ on pre-and post-abrupt changes in Ta (annual temperature) and Tmin over the TP shows remarkable differences in SST, SWJ, and TEJ. A lag correlation between Ta/Tmin, SST, and SWJ/TEJ shows that changes in SST occur ahead of changes in Ta/Tmin by approximately one to three seasons. Partial correlations between Ta/Tmin, SST, and SWJ/TEJ show that the effect of SWJ on Ta/Tmin is more significant than the effect of SST. Furthermore, simulations with a community atmospheric model (CAM3.0) were performed, showing a remarkable increase in Ta over the TP when the SST increased by 0.5 • C. The main increase in Ta and Tmin in the TP can be attributed to changes in SWJ. A possible mechanism is that changes in SST force the TEJ to weaken, move south, and lead to increased SWJ and movement of SWJ northward. Finally, changes in the intensity and location of the SWJ cause an increase in Ta/Tmin. It appears that TP warming is governed primarily by coherent TEJ and SWJ variations that act as the atmospheric bridges to remote SSTs in warm-pool forcing.Citation: Wang, C. H., L. Yu, and B.
