We construct numerical solutions to the stochastic Stokes equations on the unit sphere with additive noise. By characterising the noise as a tangential vector field, the weak formulation is derived and a spectral method is used to obtain a numerical solution. The theory is illustrated through a numerical experiment. References- P. Benner and C. Trautwein. Optimal distributed and tangential boundary control for the unsteady stochastic Stokes equations.
