Explore a comprehensive seminar presentation by Dr. Corentin Herbert from ENS-Lyon examining the critical topic of bifurcations in large-scale tropical atmospheric circulation. Delve into the analysis of tipping points and their potential role in abrupt climate change, drawing insights from paleoclimate records that suggest decade-scale transitions. Learn about theoretical mechanisms behind tropical atmosphere circulation changes, focusing on superrotation (reversal of mean zonal winds) and Hadley cell collapse (meridional circulation). Examine numerical simulations across various model complexities and understand how Rossby wave resonance influences these atmospheric phenomena. Discover the implications of superrotation transitions on the water cycle and surface temperature through radiative feedbacks, providing valuable insights into climate system dynamics and potential future changes.
