Elastic Non-Uniform FFT (ENUFFT) spectral reconstruction of irregularly sampled orography on unstructured grids
Tridib Banerjee, Felix Jochum, Ulrich Achatz
Subgrid-scale orography remains a leading source of uncertainty in numerical modeling because terrain spectra must be recovered from irregularly sampled elevation data and then red…

Split-explicit external mode solver in finite volume sea ice ocean model FESOM2
Tridib Banerjee, Patrick Scholz, Sergey Danilov +2
A novel split-explicit (SE) external mode solver for the Finite volumE Sea ice-Ocean Model (FESOM2) is presented. It is compared with the semi-implicit (SI) solver currently used i…

Discrete variance decay analysis of spurious mixing
Tridib Banerjee, Sergey Danilov, Knut Klingbeil
Expressions for local discrete variance decay (DVD) rates are directly derived from discrete tracer equations without any assumptions on discrete fluxes of the second moment. Spuri…
