Explore the intricacies of global overturning circulation in this comprehensive lecture by Anand Gnanadesikan. Delve into the methods and evidence used to understand large-scale oceanic processes as part of a pedagogical program on mathematical modeling of climate, ocean, and atmosphere processes. Learn about fluid dynamics of the atmosphere and ocean, and their impact on climate-scale phenomena. Gain insights into topics such as turbulent dynamics, convection in the ocean, monsoon dynamics, and the application of dynamical systems and machine learning techniques to atmosphere-ocean processes. Designed for students, particularly those at the Masters and final year undergraduate levels, this lecture requires no prior background in climate-atmosphere-ocean dynamics. Participate in an inclusive learning environment that encourages diversity and the participation of underrepresented groups in the field of theoretical sciences.
