Simulated Trends in Land Surface Sensible Heat Flux on the Tibetan Plateau in Recent Decades

The spatial distribution and temporal variation of land surface sensible heat (SH) flux on the Tibetan Plateau (TP) for period 1981–2018 were studied using simulation results from Noah-MP model. simulated SH fluxes also compared with SEBS model derived 80 meteorological stations. It is found that, much larger annual mean occurred western central TP eastern TP. Meanwhile, inter-annual variations than that showed did across most There was a trend decrease in mid-1980s to beginning 21st century simulations. Both an increasing after this decrease. appeared later In simulation, values temperature difference between ground air (Ts–Ta) Ts–Ta wind speed decreased approximately 2000, then increased slightly. However, transition speed. Changes (Ts) main cause decreasing trends changes contributed substantially before 1998.
