| Research Abstract |
In this study, we present a quantitative evaluation of the changes in the heat and water budgets of the Tibetan Plateau induced by the increase in atmospheric temperature over the last several decades. First, climate data obtained from meteorological observatories was re-evaluated by considering the influence of changes in the local observed environment. As a result, we obtained the actual increase in atmospheric temperature over the Tibetan Plateau. Next, we developed a new method for evaluating the heat and water budgets of the earth’s surface, including lakes and marshes as well as soil and snow cover. Finally, using satellite data and the reanalysis and meteorological observatory data, we evaluated the heat and water budgets of the Plateau and elucidated trends in their long-term changes induced by the increase in atmospheric temperature
