The initial response of a density-stratified fluid in a rectangular domain to a surface stress is modelled numerically. The model is laminar, two-dimensional and non-hydrostatic. Upwelling of deep fluid at the upwind end of the fluid is critical to the subsequent evolution of the stratification. It is confirmed that upwelling is a wave process and consideration of flow at the upwind end-wall illustrates the flow structure of partial upwelling. Numerically, to ensure adequate penetration of surface stress, an increased viscosity is needed. Comparisons are made between the present numerical results and previously published experimental observations.
