Vegetation change on the Tibetan Plateau (1982 to 2006): An attribution by the rainfall-runoff chain  Danlu Cai, Klaus Fraedrich, Frank Sielmann, Ling Zhang, Xiuhua Zhu  Hamburg, Germany   Employing ERA-Interim and suitably projected NDVI-vegetation data, the rainfall–runoff chain is applied to the Tibetan Plateau to (i) analyze the rainfall-runoff chain changing between the two periods of global temperature rise (1973 – 1993) and stagnation (1994 – 2008) and (ii) to attribute climate versus human effects. The rainfall runoff chain is based on a biased coinflip Ansatz, which provides an equilibrium stochastic watershed scale model of. The solution yields the empirically derived (and widely used Schreiber formula as an Arrhenius-type equation of state W = exp(-D) which, associated with two thresholds, combines river runoff Q, precipitation P and potential evaporation N as flux ratios W=Q/P and D=N/P. This approach, which has been successfully used to relate paleo climates with lake area estimates (e.g. Qinghai Lake) is now tested for attribution to climate and human induced change.    ---------------------------------- Key words: vegetation, rainfall, runoff, Tibetan Plateau
