Marilyn Raphael

Marilyn Raphael. She is a prominent American geographer and climatologist renowned for her extensive research on the Southern Hemisphere climate system, with a particular focus on Antarctica and the Southern Ocean. As a professor in the Department of Geography at the University of California, Los Angeles (UCLA), her work has significantly advanced the understanding of Antarctic sea ice variability, atmospheric circulation patterns like the Southern Annular Mode, and their connections to global climate. Raphael is also a dedicated educator and mentor, recognized for her contributions to academic leadership within the field of physical geography.

Early life and education

Marilyn Raphael completed her undergraduate education at the University of the Witwatersrand in Johannesburg, South Africa, where she developed a foundational interest in atmospheric science. She then pursued graduate studies in the United States, earning her Master of Arts and Doctor of Philosophy degrees in geography from Ohio State University. Her doctoral research, conducted under the guidance of experts in polar climatology, investigated large-scale atmospheric dynamics influencing the Antarctic Peninsula, laying the groundwork for her future specialization. This academic path positioned her at the intersection of meteorology and geophysical fluid dynamics, shaping her approach to climate science.

Academic career

Following her Ph.D., Marilyn Raphael joined the faculty of the Department of Geography at the University of California, Los Angeles, where she has remained a central figure. She has held significant administrative roles, including serving as Chair of the department, where she influenced curriculum development and faculty recruitment. Raphael is a core member of the UCLA Institute of the Environment and Sustainability and has been actively involved with the National Center for Atmospheric Research (NCAR) through various collaborative projects. Her teaching, which covers topics from global climate change to statistical methods in geography, has been honored with the UCLA Distinguished Teaching Award, underscoring her impact on generations of students.

Research and contributions

Marilyn Raphael's research is primarily centered on the climate of the high southern latitudes, utilizing a combination of satellite data, reanalysis products, and climate model simulations. A major focus has been the analysis of Antarctic sea ice extent and its links to atmospheric teleconnections, particularly the Southern Annular Mode (SAM) and the Pacific–South American pattern. Her work has elucidated how phenomena like El Niño–Southern Oscillation (ENSO) can modulate sea ice conditions around West Antarctica. Raphael has also published influential studies on the Antarctic ozone hole's role in driving changes in Southern Ocean wind patterns and subsequent impacts on ocean circulation and ice sheet stability, contributing critical knowledge to the Intergovernmental Panel on Climate Change (IPCC) assessments.

Awards and honors

In recognition of her scholarly achievements, Marilyn Raphael was elected as a Fellow of the American Association of Geographers (AAG), one of the highest honors in the discipline. She received the UCLA Distinguished Teaching Award for her exceptional pedagogical contributions. Her research leadership has been acknowledged through invitations to serve on advisory panels for the National Science Foundation (NSF) and the United States Antarctic Program (USAP). Raphael has also been a valued member of editorial boards for prominent journals such as the Annals of the American Association of Geographers and Polar Geography, helping to steer the direction of research in her field.

Selected publications

Raphael's body of work includes numerous peer-reviewed articles and book chapters that are widely cited. Key publications often appear in journals like the Journal of Climate, Geophysical Research Letters, and the International Journal of Climatology. Notable works include studies on the seasonal evolution of the Southern Annular Mode, analyses of the atmospheric forcing of sea ice concentration in the Bellingshausen Sea, and investigations into the response of Antarctic surface temperature to stratospheric ozone depletion. Her research frequently involves collaboration with scientists from institutions such as NASA, the British Antarctic Survey, and Columbia University.
