Joint Seminar: Precipitation Change Attribution in the Pan-Third Pole: A Circulation-Based Perspective
Anthropogenic external forcings—such as greenhouse gas emissions and aerosol releases—superimposed on internal climate variability, jointly influence long-term precipitation changes and, in turn, impact other components of the climate system. However, due to the influence of internal variability and limitations in climate models, detecting and attributing regional-scale precipitation trends remains a major challenge. The Pan-Third Pole region, centered on the Tibetan Plateau and extending into Central Asia and surrounding areas, is a climatically sensitive area characterized by strong multi-sphere interactions and influenced by both westerlies and monsoons. In this study, we develop a regional precipitation attribution framework that integrates large-scale atmospheric circulation. By identifying dominant precipitation variability patterns and associated circulation systems, we systematically investigate the respective contributions of internal variability and anthropogenic forcings to precipitation changes in the Pan-Third Pole region since the 1950s, providing new insights into the mechanisms driving regional climate change.
