Laure E. Zanna is a climate scientist and associate professor in the Clarendon Laboratory at the University of Oxford. She works on climate system dynamics and the influence of the oceans on global scales.[1][2][3] In July 2019, she was awarded the Nicholas P. Fofonoff Award for Early Career Research by the American Meteorological Society.[4]
Early life and education
Zanna studied physics at Tel Aviv University and graduated in 2001.[5] She earned a master's degree at the Weizmann Institute of Science. She was a doctoral student under Eli Tziperman at Harvard University. Her PhD dissertation looked at Atlantic Ocean circulation.[6] She developed a model that could visualize thermohaline circulation.[7]
Research and career
Zanna was appointed as a junior research fellow at Balliol College, Oxford, in 2009. She was appointed to the Oxford Martin School and made an Associate Professor in Physics in 2011. She was made a Fellow of St Cross College, Oxford in 2011. There, she worked on Meridional Overturning Circulation anomalies.[8] She was a lecturer at Christ Church, Oxford from 2014 to 2018, when she was appointed as a David Richards Fellow at Wadham College, Oxford.[9] Her work applies mathematical models to ocean data.[10] By understanding how ocean heat has changed in the past, Zanna's work helps make more accurate predictions about climate change.[11][12][13][14]
Zanna uses Green's function methods to relate observations of sea surface temperatures to the temperatures of the deep ocean.[15] By using an ocean transport model, Zanna demonstrated that temperature could be treated as a passive variable that did not impact circulation.[15] She demonstrated that atmospheric heat is mainly stored in the deep sea, with oceans storing up to 93% of the heat of climate change.[15][16][17] Specifically, the models developed by Zanna and her group showed that the deep oceans have absorbed 436 zettajoules of energy in the past 150 years.[18] This represents around 1,000 times the worldwide human energy consumption, or 1.5 atomic bombs every second for 150 years.[19][20] She also found that major ocean currents that transport nutrients and heat are changing.[17]
Recently, her group demonstrated that it is possible to use deep learning and sub-grid parametrisation to analyse ocean data.[21][22] She is due to join the New York University Center for Atmosphere Open Science in 2019.[23]
