Forecast: climate conversations with Michael White
Sarah Kang from the Ulsan National Institute of Science and Technology tells Mike about her work to understand the atmospheric and oceanic dynamics that link the extratropics to the tropics. Paleoclimate research has long shown that climate perturbations with strong Northern Hemisphere imprints — like Dansgaard-Oeschger events — are associated with movements of the Intertropical Convergence Zone (ITCZ). But it took a long time for a theoretical understanding to emerge, and Sarah spent much of her PhD at GFDL and postdoc at Lamont probing some of the many mechanisms at work. Recently, work focused on the Southern Ocean seemed to reveal that the tropics might respond fundamentally differently to southern vs. northern forcings. Ongoing work by Sarah and her colleagues, however, is now pointing to a related mechanism, but one that is driven instead by the Southern Ocean’s vast capacity to redistribute heat. Sarah is co-leading the Extratropical-Tropical INteraction model intercomparison project, which should lead to a sharper understanding and perhaps a clearer insight into future changes.
Sarah discusses her experiences navigating a career in Korea: being the only woman out of a faculty of 21; going on sabbatical before getting tenure; the intense focus on metrics in the tenure process; and having a husband who is the only doctor who’s ever taken parental leave at his hospital.
Sarah is the only guest on Forecast who’s (1) gone into precisely the same career as a parent and (2) gotten her PhD from her father’s postdoc advisor (the brilliant Isaac Held)! But it wasn’t because she found her father’s line of work so compelling. It was the lifestyle, the people, and the passion — something that a lot of scientists can doubtless relate to.
