Dr. Marilyn Raphael is Professor of Geography at UCLA and served as Department Chair from 2010-2013. Her primary research focus is Southern Hemisphere (SH) atmospheric dynamics and climate change and her major scientific goals are to characterize the Antarctic sea ice variability and to define and understand the interaction between Antarctic sea ice and the large-scale Southern Hemisphere circulation, focusing on interaction at the seasonal, interannual and decadal time scales. Her work includes globalclimate modeling with an emphasis on improving the simulation of sea ice and the atmosphere in the Southern Hemisphere. She is currently Chair of the Scientific Committee on Antarctic Research’s expert group, Antarctic Sea ice Processes and Climate (ASPeCt) and Co-Chair of the World Climate Research Programme’s (WCRP) Polar Climate Predictability Initiative (PCPI).
