Dust and Wildfire Processes in Land-Atmosphere Interactions
July 14, 2023 (Friday) 14:00-15:30
The land ecosystem and the atmosphere system interact with each other through the exchange of matter and energy between the land and the atmosphere. Processes such as dust and wildfire are regulated by both the land and the atmosphere, bringing changes to the regional climate and the land ecosystem. The aerosols stemming from these processes assume a pivotal role in global energy balance, the water cycle, and the dispersal of nutrients through extensive long-range transport. This report delves into dust and wildfire processes in land-atmosphere interactions, specifically encompasses: (1) the reciprocal impact of vegetation and soil disruption on regional climate and their driving effects on dust and wildfire; (2) compound extreme events of wildfire and dust amidst global changes.
Yu Yan is an assistant professor and researcher in the Department of Atmospheric and Oceanic Sciences at Peking University, as well as a Boya Young Scholar. She earned her Bachelor's degree in Environmental Engineering from Tsinghua University, and her Master's and Ph.D. degrees in Environmental Science and Statistics, and Atmospheric and Oceanic Sciences respectively, from the University of Wisconsin-Madison. She conducted postdoctoral research at the Jet Propulsion Laboratory of the California Institute of Technology and Princeton University. In 2021, she was selected for a national-level young talent program and joined Peking University. Her primary focus is on exploring dust and wildfire processes amid global changes. The rewards she has received include the NASA Postdoctoral Fellowship, Xie Yibing Young Meteorological Technology Award, and World Meteorological Organization Young Scientist Research Award.
