SUMMARY:Understanding fluid dynamics for climate using reduced models - St
 even Tobias (University of Leeds)
DTSTART:20240523T110000Z

UID:TALK215785@talks.cam.ac.uk
DESCRIPTION:Fluid dynamics for climate (and indeed for geophysics and astr
 ophysics more generally) requires the modelling of nonlinear process over 
 a vast range of spatial and temporal scales. Current (and future!) computa
 tional methods are not capable of modelling the range of scales required\,
  so some compromises are required. In this talk I will describe possible m
 ethods for modelling the types of interaction that are needed for problems
  of relevance to the climate. I will focus on two methods\; the generalise
 d quasilinear approximation\, which is a first step to providing robust co
 nservative\, realisable\, subgrid models and the solution of the PDEs on a
  logarithmic lattice.&nbsp\;\nThis is joint work with Curtis Saxton (Leeds
 )\, Rich Kerswell (Cambridge)\, Keaton Burns (MIT) and Brad Marston (Brown
 ).
