Introduction to the Lecture:

The terrestrial ecosystem and the climate system interact through mass and energy exchange between the ground and the atmosphere. The processes of sand dust and wildfire are controlled by land surface and atmosphere, and change the regional climate and terrestrial ecosystem. Aerosols produced by dust storms and wildfires play an important role in global energy budget, water cycle and nutrient redistribution through long-distance transmission. Based on multi-source observation and multi-scale process models, this report explores the process of sand dust and wildfire in land-air interaction, including: (1) the feedback effect of vegetation and soil disturbance on regional climate and its driving effect on dust and wildfire; (2) wildfire-sand dust combined extreme events under global change.

Profile of the Speaker:

Yu Yan is Assistant Professor, Researcher and Boya Young Scholar in the Department of Atmospheric and Oceanic Sciences of Peking University School of Physics. She obtained her B.S. (Environmental Engineering, 2010) from Tsinghua University, and M.S. (Environmental Science and Statistics) and Ph.D. (Atmospheric and Oceanic Science, 2017) from the University of Wisconsin-Madison. She has conducted postdoctoral research in the Jet Propulsion Laboratory of the California Institute of Technology, the University of California, Los Angeles, and Princeton University. She joined Peking University in September, 2021. She mainly explores the interaction between land and atmosphere, especially the response and feedback of sand dust and wildfire processes under the global climatic and environmental changes.
