Temperature Front Formation in Stably Stratified Turbulence

Explore a comprehensive seminar lecture examining temperature front formation in stably stratified turbulence, delivered by Professor Yoshifumi Kimura from Nagoya University. Delve into the complex interactions between waves and vortices in both 2D and 3D stably stratified turbulence through Direct Numerical Simulation (DNS) of the Navier-Stokes equations under the Boussinesq approximation. Learn about the formation of sharp vertical temperature fronts exhibiting sawtooth wave structures, and understand how these cliff-ramp structures lead to non-symmetric PDFs of vertical temperature fluctuation derivatives. Investigate the underlying mechanisms causing asymmetry in these structures and gain insights into the mixed dimensionality aspects of stratified turbulence dynamics.
