Study Director:


Dr. Chris Bretherton - (Chair)
University of Washington

Chris Bretherton is currently a Professor in the University of Washington Departments of Atmospheric Science and Applied Mathematics, where he teaches classes on weather, atmospheric turbulence and cumulus convection, tropical meteorology, geophysical fluid dynamics, numerical methods, and classical analysis of ODEs and PDEs. He directs the University of Washington Program on Climate Change, which organizes graduate courses, seminars, a summer institute, and research on climate science and its relevance to our society and future. His group developed the parameterizations of shallow cumulus convection used in the cutting-edge versions of two leading US climate models, the National Center for Atmospheric Research Community Atmosphere Model, version 5 (CAM5), and the Geophysical Fluid Dynamics Laboratory Atmosphere Model, version 3 (AM3). They also developed the turbulence parameterization used in CAM5, and have versions of both schemes for the Weather Research and Forecast (WRF) regional modeling system.

Since 2005, she has also been a Founding Co-Director of the Berkeley Institute of the Environment. Inez Fung has been studying climate change for the last 20 years. She is a principal architect of large-scale mathematical modeling approaches and numerical models to represent the geographic and temporal variations of sources and sinks of CO2, dust and other trace substances around the globe. Dr. Fung???s recent work in climate modeling predicts the co-evolution of CO2 and climate and concludes that the diminishing capacities of the land and oceans to store carbon act to accelerate global warming. Inez Fung received her S.B. in Applied Mathematics and her Sc.D. in Meteorology from MIT. She joined the Berkeley faculty in 1998 as the first Richard and Rhoda Goldman Distinguished Professor in the Physical Sciences and the founding Director of the Berkeley Atmospheric Sciences Center.


Dr. Thomas L. Delworth
Geophysical Fluid Dynamics Laboratory

Thomas L. Delworth is a Research Scientist and group leader in the Climate Change, Variability and Prediction Group at NOAA???s GFDL. His research is largely focused around decadal to centennial climate variability and change through the synthesis of climate models and observational data. On these time scales the behavior of the climate system is a mixture of natural variability combined with the response of the climate system to changing radiative forcing induced by changing greenhouse gases and aerosols. Understanding the natural variability of the climate system on decadal scales is critical to their ability to detect climate change, and to understand the processes responsible for observed change from the global to the regional scale.
