 d2ca89b7\nHasselmann’s paradigm in 3D via (LA)-SALT\nAbstract:\nThe Cris
 an–Holm–Korn (2023) paper realises Hasselmann’s paradigm — fast st
 ochastic atmosphere driving a slow deterministic ocean — in a 2D coupled
  (LA)-SALT model. I present a 3D extension at the discrete level\, on Dela
 unay–Voronoi meshes. The reformulation is more than a translation. In fi
 nite dimensions\, the two Kelvin circulation theorems — one per componen
 t — hold pathwise on discrete cycles rather than in expectation\, and CH
 K’s infinite-dimensional machinery collapses to elementary SDE theory. E
 nergy estimates yield global existence. The discrete LA-SALT system recove
 rs Hasselmann’s red-spectrum mechanism as a closed linear ODE\; I close 
 by sketching how an Ornstein–Uhlenbeck-coloured stochastic ocean would e
 xtend the framework to genuine two-time-scale dynamics.\nSchedule\n1200-13
