Melissa S. Bukovsky is a post-doctoral fellow at the National Center for Atmospheric Research working directly with NARCCAP. Her research revolves around regional climate model credibility and diagnostics. She is interested in the determination of model credibility through process-based analysis and the impact of model bias/error and its propagation in simulations from the present-day to the future. Current, specific areas of research include the ability of the NARCCAP models to simulate central U.S. warm-season precipitation, the North American monsoon, observed trends, and the related processes behind these features.

Bill Gutowski

William J. Gutowski, Jr. is professor of meteorology in the Department of Geological and Atmospheric sciences at Iowa State University, with a courtesy appointment in agronomy.

Dr. Gutowski's research concentrates on the role of atmospheric dynamics in climate. Central focuses are the dynamics of the hydrologic cycle, regional climate and changes in extreme weather and climate. Because processes on a wide range of spatial and temporal scales are important for all of these, his research program entails a variety of modeling and data analysis approaches. The regional research uses models covering only a portion of the earth (limited-area models) and global models whose resolution varies with location (stretched-grid models). Data analysis approaches include study of spatial patterns and analysis of precipitation and energy spectra. His work includes regional modeling of African, Artic and East Asian climates and has significant collaboration with scientists in these regions. Much of his work is through the Regional Climate Modeling Laboratory, which he coordinates with Dr. Eugene Takle and Dr. Ray Arritt. Within NARCCAP, he is coordinating with Iowa State colleagues the NCEP-driven simulations and their analysis. He has also helped with development of the NARCCAP archive.

Dr. Gutowski currently serves as an Editor for the Journal of Hydrometeorology. He is a lead author for the IPCC Fifth Assessment Report (Working Group 1, Chapter 12). He also is a member of the U.S. National Academy/Water Science and Technology Board panel evaluating emerging challenges and opportunities in the hydrologic sciences. He was a Lead Author for two U.S. Climate Change Science Program reports (CCSP 3-1, Climate Models: An Assessment of Strengths and Limitations; CCSP 3-3, Weather and Climate Extremes in a Changing Climate) and a contributing author to the IPCC Third and Fourth Assessment Reports. In addition, he was a member of the U.S. National Academy/Transportation Research Board panel to study the impacts of climate change on transportation. Dr. Gutowski received a Ph.D. degree in meteorology from the Massachusetts Institute of Technology and a Bachelor of Science degree in astronomy and physics from Yale University.

Ruby Leung

Ruby Leung is a Laboratory Fellow at the Pacific Northwest National Laboratory (PNNL) and an Affiliate Scientist at the National Center for Atmospheric Research. She received her MS and Ph.D. in Atmospheric Science from the Texas A&M University in 1988 and 1991. She has performed much of her research using regional climate models since the early 1990s when she developed a regional climate model with special features that account for the subgrid scale effects of topography, lake and vegetation. Her model enables the coupling of climate and hydrologic processes in regions with complex orography. Since then Dr. Leung has led several projects to examine the impacts of climate variability and change and the effects of aerosols on the regional hydrological cycle. In 2001, Dr. Leung organized the Workshop on "Regional Climate Research: Needs and Opportunities" co-sponsored by the National Science Foundation and Department of Energy to examine various approaches to modeling regional climate. In 2005, she organized the Workshop on "Research Needs and Directions of Regional Climate Modeling Using WRF and CCSM". The workshop identified the needs to develop capability for high resolution modeling, regional earth system modeling and up scaling. More recently, she is leading an effort to use a hierarchical evaluation approach to assess global high resolution, global variable resolution, and regional climate models for modeling climate at the regional scale. She is a member of the NRC study committee on "A National Strategy for Advancing Climate Modeling". Dr. Leung is a fellow of the American Association for the Advancement of Science and American Meteorological Society.

Gene Takle

Eugene S. Takle is professor of Atmospheric Sciences and Agricultural Meteorology at Iowa State University.

Eugene's current climate-related research includes both basic research on climate change and impacts of climate change. Basic research centers on how the features of the earth surface influence turbulent flow and exchange processes that influence surface momentum, energy, and moisture fluxes. Research on climate-change impacts includes assessing the interactive roles of climate and land-manager choices on land-use/land-cover change in agricultural area, development and evaluation of downscaling tools for near-surface flow and impacts of climate change on wind power, evaluating effects of climate changes on Midwest agroecosystems using a climate-crop coupled model, and assessment of variability and trends in Iowa climate data on pavement performance by use of a mechanistic-empirical pavement design model. The land-use/land-cover project uses SWAT (Soil and Water Assessment Tool) to simulate streamflow in large complex watersheds in agricultural areas under current and future scenario climates. Changes in surface wind speed and wind power over the 20th and 21st Centuries are explored through use of statistical downscaling and regional climate models. By coupling crop models with regional climate models we explore the impact of crop selection on carbon uptake and evapotranspiration over the Midwest during the growing season. Roadways in Iowa have been designed under assumptions of average climate conditions that do not reflect actual climate variability or future climate change. Working with civil engineers we are using a standard pavement design model to explore expected changes in various roadway failure modes under actual variability and projected trends in climate over the next 60 years.

Eugene's role in NARCCAP is as part of the ISU team organizing and analyzing the reanalysis-driven runs and contributing to the scenario-driven runs. A central focus is promoting appropriate and effective use of regional climate model information in impacts studies.
