Objectives :
1/ Comparing two LES and their ability to simulate the late afternoon transition (LAT).<br>2/ Studying the turbulence characteristics during the LAT : results found in the literature are revisited and further analyzed.<br>This comparison investigates:<br>? the validity of mixed layer scaling,<br>? the 'S' shape of the buoyancy flux,<br>? the decay of turbulent kinetic energy (TKE),<br>? the time evolution of turbulent length scales.
