Predicting the Climate Over the Tibetan Plateau in Decadal Scales

Explore the challenges and advancements in predicting the climate over the Tibetan Plateau on decadal scales in this comprehensive conference talk. Delve into the importance of the Tibetan Plateau in global air-land-sea interactions and the limitations posed by observational scarcity. Learn about the innovative approach of assimilating extra-regional observations through a global coupled data assimilation (GCDA) system to improve data quality and decadal climate prediction skills. Discover how the DRP-4DVar assimilation method and the FGOALS-g2 climate system model are utilized to develop an advanced GCDA system. Examine the significant improvements in predicting summer precipitation and temperature over the Tibetan Plateau, outperforming many CMIP5 model predictions. Understand the role of the Atlantic Multidecadal Oscillation in affecting the Tibetan Plateau's summer climate. Investigate the impact of assimilating atmospheric and land surface observations from the Tibetan Plateau on global climate predictions, including sea level pressure, sea surface temperature, and various climate indices. Gain insights into the important influence of the Tibetan Plateau's atmospheric and land surface conditions on global climate change through the lens of coupled data assimilation.
