Marilyn Raphael is a professor and former Chair of the Department of Geography at the University of California, Los Angeles. She is co-Chair of the SCAR expert group Antarctic Sea ice Processes and Climate (ASPeCt) and co-Lead of the WCRP’s Polar Climate Predictability Initiative (PCPI). Her research interests are in climate variability and change particularly in the high latitude Southern Hemisphere. Her research focuses on understanding the interaction between Antarctic sea-ice variability and the large-scale atmospheric circulation using both largescale observational databases and global climate models. Her current projects focus on understanding the recent trends in the west Antarctic sea ice zone with an emphasis on understanding the contributions of the atmosphere.
