Explore the fundamentals of geophysical fluid dynamics in this 58-minute lecture by Jim Thomas from the International Centre for Theoretical Sciences. Part of a pedagogical program on mathematical modeling of climate, ocean, and atmosphere processes, this talk introduces key concepts in fluid dynamics as applied to Earth's atmosphere and oceans. Gain insights into how these principles impact climate-scale processes, with no prior background in climate-atmosphere-ocean dynamics required. Ideal for Masters students, final year undergraduates, and anyone interested in understanding the physical mechanisms driving our planet's fluid systems.
