New Study Shows that Oceanic Lee-Waves Make an Impact on Large-Scale Circulation and Climate -- Indicating the Importance of Including this Process in Climate Models

Monday, Mar 10, 2014

Former AOS Postdoc Angélique Melet, currently a postdoc at CNES/LEGOS in France, is the lead author of new paper that explores the combined effects of internal tide– and lee wave–driven mixing on the ocean state.   This is the first time the effect of oceanic lee-waves has been parameterized in a climate model. The results show that lee-waves make an impact on the large-scale circulation and climate, indicating the importance of including this process in climate models. AOS Faculty Members Robert Hallberg, a GFDL oceanographer, and Sonya Legg are coauthors on the study, along with Maxim Nikurashin, a lecturer/research fellow at the Institute for Marine and Antarctic Studies, University of Tasmania and a former AOS associate research scholar. The paper, "Sensitivity of the Ocean State to Lee Wave–Driven Mixing," is published in the March issue of the Journal of Physical Oceanography and can be found here.
