Kerry Emanuel is a professor of atmospheric science at the Massachusetts Institute of Technology. His research interests focus on tropical meteorology and climate, with a specialty in hurricane physics. Emanuel is the author or coauthor of over one hundred peer-reviewed scientific papers and two books, including Divine Wind: The History and Science of Hurricanes, recently released by Oxford University Press. It received the 2007 Louis Battan Author's Award from the American Meteorological Society. Sigma Xi Spring Lecture.
Synopsis of Lecture:
Analysis of historical records of hurricane activity reveals large variability from one decade to the next. How much of this variability is random, how much can be said to be part of natural, regional or global climate fluctuations (such as El Nino), and how much is tied to man-made global climate change? These are important questions, as their answers bear on the pressing question of how hurricane activity might change over the next century. I will review the evidence that hurricane activity is closely linked to sea surface temperature and then examine the various environmental processes that cause sea surface temperature to change, focusing on the role of human-induced climate change.
