During December 2025, François Poulin developed the SphericalCoriolis feature for the CliMA/Oceananigans.jl repository, focusing on enhancing the simulation of Coriolis forces on a sphere. He designed a new SphericalCoriolis structure in Julia, supporting both hydrostatic and nonhydrostatic formulations, which replaced the previous HydrostaticSphericalCoriolis implementation. This work improved the flexibility and accuracy of numerical modeling in oceanographic simulations by allowing users to select between different physical schemes. Drawing on expertise in scientific computing and simulation development, François delivered a well-structured solution that broadens experimentation and increases the realism of spherical ocean simulations without introducing new bugs.
