Career Overview
Dr. Yang joined Nanjing University in 2012 and currently is an associate professor at School of Atmospheric Sciences. He received his B.S. and Ph.D. in atmospheric sciences from Nanjing University. He was studying as a visiting scholar in the Pacific Northwest National Laboratory (PNNL) for two years when he was a Ph.D. candidate. Dr. Yang’s research passion has been the development of cloud and precipitation parameterizations and uncertainty quantification in climate modeling. He has established a new scheme that can represent transitions from shallow to deep and to organized convection, which improves the physical consistency of cloud dynamics across different convective regimes and the consistency between macro- and micro-physics of convection. Meanwhile, he has developed the uncertainty quantification method and auto-tuning approach for climate models that usually have numerous physical parameters. He has also been working on the interactions among cloud/precipitation processes, radiation, and circulation as well as their climatic impacts. Dr. Yang has published more than 60 scientific papers and received many prestigious awards. His scheme has been implemented in the Earth system models of China Meteorological Administration (CMA) and Tsinghua University. His research findings have provided key physical parameters for model development in the climate model community, for the planning of new field studies jointly organized by the U.S. Department of Energy and other institutions, and for the designment of ensemble strategy for climate prediction operated by CMA.
