Land surface properties plays a significant role in modulating local and regional climate through the exchange of heat, moisture, and momentum between land and atmosphere. Any changes in land surface characteristic, therefore, have impact on both radiative and nonradiative biophysical properties which in turn affect the climate system through surface energy balance. The Tibetan Plateau (TP) is the important landmass of the earth and has profound impacts on the local, regional and global climate. The mechanical and thermodynamic forcing of TP is crucial in influencing the regional and global climate. Therefore, it is important to understand the contributions of dynamic and thermodynamic effects of vegetation change on regional climate in the Tibetan Plateau. In this study, we used AVHRR Normalized Difference Vegetation Index (NDVI) to reanalyze the spatiotemporal patterns of vegetation change on the TP during 1982–2015. For this we examine the the near-surface and upper atmospheric conditions to derive the plausible physical mechanisms affecting the regional climates associated with changing vegetation.
