Particle relabelling symmetries and Noether's theorem for vertical slice models
Colin J. Cotter, Michael J. P. Cullen
We consider the variational formulation for vertical slice models introduced in Cotter and Holm (Proc Roy Soc, 2013). These models have a Kelvin circulation theorem that holds on a…

Estimating eddy diffusivities from noisy Lagrangian observations
C. J. Cotter, G. A. Pavliotis
The problem of estimating the eddy diffusivity from Lagrangian observations in the presence of measurement error is studied in this paper. We consider a class of incompressible vel…
