I am Bharath Krishnan, a doctoral researcher in subproject W6, “Spectral Energy Fluxes by Wave-Wave Interactions,” at the Leibniz Institute of Atmospheric Physics (IAP) in Kühlungsborn. My research focuses on mesoscale energy transfers in regional domains within the mesosphere and lower thermosphere (MLT). Various fundamentally different theories, ranging from gravity waves to stratified turbulence and wave-vortex interactions, have been proposed to explain the mesoscale dynamics. However, the role of gravity wave breaking and its associated energy transfers in the upper atmosphere remain relatively underexplored. To gain deeper insight into gravity wave dynamics and share my recent findings, I participated in the 6th Gravity Wave Workshop in Prague from August 24th to 26th. more ›

Philomène is a PhD student at the University of Hamburg and a member of the sub-project T2: Ocean Surface Layer Energetics). From June, 29 to July, 3 2026, she participated in the third workshop of the trimester programme Mathematical Developments in Geophysical Fluid Dynamics, titled Idealised Mathematical Models for Geophysical Flows, held at the Institut Henri Poincaré in Paris, and talks about her experiences. more ›

Genevieve Beauregard is a doctoral candidate at Universität Hamburg in the Theoretical Oceanography group. Within TRR 181, she investigates how large-scale ocean circulation in climate models depends on ocean mixing and overturning, and how diagnostic methods can reveal whether those processes in the models are doing what they should. more ›
