Explore the complex dynamics of heat waves through Reynolds decomposition in this informative conference talk. Delve into the theoretical and practical perspectives of geophysical fluid dynamics as Joy Merwin Monteiro from the International Centre for Theoretical Sciences breaks down the components of heat wave phenomena. Learn how this mathematical technique can be applied to analyze and understand the multi-scale interactions and energy transfers that contribute to extreme temperature events. Gain insights into the challenges of quantifying energy transfers across different scales in atmospheric dynamics and how this knowledge can improve climate modeling and prediction. Part of a comprehensive two-week program covering various aspects of geophysical fluid dynamics, this 28-minute presentation contributes to the broader discussion on eddies, waves, turbulence, and their roles in shaping Earth's climate system.
