L. author Talley, L. D. author Yeager, Stephen author UCAR/NCAR - Library publisher Plain Language Summary The annual cycle of the Somali Current is studied using a forced strongly eddy-active global ocean general circulation model. The annual cycle and timing of the reversal of the Somali Current differ depending on the location along the coast of northeastern Africa. A momentum budget analysis calculated from the model output shows that both annual Rossby waves and the life cycle of the Great Whirl impact the northern part of the Somali Current (roughly 5 degrees N to 10 degrees N). In particular, the nonlinear term is of leading order importance when the Great Whirl is present. This is in contrast to the leading-order geostrophic balance between 2 degrees N and 5 degrees N. South of 2 degrees N, equatorial dynamics prevail, and the nonlinear term is again important, and its reversal is strongly affected by the northward flowing East African Coastal Current. Alongshore wind forcing is influential at all latitudes, but only the transition in flow direction during boreal spring between 2 degrees N and 5 degrees N directly follows that of the wind.
