Expertise and Research Interests

Richard Somerville is a theoretical meteorologist whose research interests include geophysical fluid dynamics, thermal convection, computational methods, predictability, atmospheric modeling, numerical weather prediction, radiative transfer, cloud physics, and climate.

Other Expertise

Richard Somerville is a Coordinating Lead Author in Working Group I for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, published in 2007. See http://www.ipcc.ch.

He is also a team member of the National Science Foundation Science and Technology Center for Multi-Scale Modeling of Atmospheric Processes (CMMAP). See http://kiwi.atmos.colostate.edu/cmmap/.

In addition to his work as a researcher, Richard Somerville is active in science education and outreach, beginning with advising graduate students at Scripps Institution of Oceanography, University of California, San Diego. See http://www.sio.ucsd.edu.

He is the author of an award-winning and critically acclaimed popular book, The Forgiving Air: Understanding Environmental Change. This book, written accessibly for the general public, covers leading global environmental issues such as stratospheric ozone loss and anthropogenic climate change, together with energy, population and policy implications.

He has also participated extensively in teacher professional development, given Congressional testimony, briefed U. N. climate change negotiators, and advised Federal agencies on education and outreach.

Richard Somerville comments frequently on climate and environmental issues for the print and broadcast media. He lectures widely to scientific, corporate and governmental audiences, and to the general public.

Future Research

Richard Somerville's ongoing research projects are in climate and climate change. He works with a small group of collaborators to advance our theoretical understanding of key physical processes in the climate system. Their primary focus at present and in the immediate future is on the role of clouds, cloud-radiation interactions, and cloud feedbacks in climate. The research involves using measurements from field observational programs, together with single-column models and other theoretical tools, to test and improve the ways in which computer simulations of the global climate represent the effects of clouds. Specific areas of interest include stochastic approaches to cloud parameterizations, the effects of cloud microphysics on cloud radiative properties, the characteristics of clouds in polar regions, and the role of dust and other particles in influencing clouds and climate.
