报告摘要：
Precipitation is arguably the most important weather and climate variable. How precipitation may change under anthropogenic global warming is of great concern. In this talk, I will first discuss the key precipitation characteristics, model biases in simulating these characteristics, thermodynamic and energetic constraints on global-mean precipitation, and the effect of internal variability on precipitation trends. I will then examine how precipitation has changed in recent decades, followed by model-projected changes in precipitation amount, frequency, and intensity. Finally, I will discuss the key mechanisms underlying the model-projected precipitation changes, especially on the causes of decreasing light-moderate precipitation under global warming.

Dr. Dai is a Distinguished Professor in the Department of Atmospheric & Environmental Sciences at the University at Albany, State University of New York, USA. Dr. Dai obtained his PhD in Atmospheric Science from Columbia University in 1996, then worked at the National Center for Atmospheric Research (NCAR) in Boulder, CO, first as a postdoc and then as a Scientist until 2012, when he joined the faculty of the University at Albany. Dr. Dai is an internationally renowned climate scientist with a focus on climate variability and change, Arctic climate, the global water cycle, hydroclimate, drought, the diurnal cycle, and climate data analysis. With more than 200 peer-reviewed publications, he has received around 70,000 citations with an H-index of 95. He is one of the world’s top 1% Highly Cited Researchers. Dr. Dai is ranked No. 2 and No. 21 in Meteorology/Atmospheric Science based on, respectively, 2019 citations and 1996-2019 total citations according to a Stanford study. He served as the Chair of the Climate Variability and Change Committee and Editor of Journal of Climate of the American Meteorological Society (AMS). He is an AGU and AMS Fellow.
