Kai Yang, PhD, Young Research Fellow, master supervisor. Research areas of Dr. Yang focus on the climate model, modeling and land-atmosphere interactions. He has conducted a series research works on the impacts of soil moisture anomalies related to freeze-thaw (FT) process and snow cover anomalies over Tibetan Plateau (TP) on general circulation in East Asia and response of atmosphere dynamic process to TP thermal forcing. He has also developed model parameterizations, incorporating a new water-heat transport scheme in CLM, and proposing new FT parameterizations to improve the simulation of soil moisture and temperature in clod region.
