Comparing two different types of stochastic parametrisation in geophysical flow
Darryl Holm, Wei Pan, James Woodfield
This paper investigates the effects of stochastic variations in bathymetry on the solutions of the thermal quasigeostrophic (TQG) equations. These stochastic perturbations generate…

Stochastic fluids with transport noise: Approximating diffusion from data using SVD and ensemble forecast back-propagation
James Woodfield
We introduce and test methods for the calibration of the diffusion term in Stochastic Partial Differential Equations (SPDEs) describing fluids. We take two approaches, one uses ide…
