Última Intraseasonal variability of equatorial Indian Ocean zonal currents ArchiMer Sengupta, Debasis; Senan, Retish; Goswami, B. N.; Vialard, Jerome. New satellite and in situ observations show large intraseasonal (10-60 day) variability of surface winds and upper- ocean current in the equatorial Indian Ocean, particularly in the east. An ocean model forced by the Quick Scatterometer (QuikSCAT) wind stress is used to study the dynamics of the intraseasonal zonal current. The model has realistic upper- ocean currents and thermocline depth variabilities on intraseasonal to interannual scales. The quality of the simulation is directly attributed to the accuracy of the wind forcing. At the equator, moderate westerly winds are punctuated by strong 10-40-day westerly wind bursts. The wind bursts force swift, intraseasonal (20-50 day) eastward equatorial jets in spring, summer, and fall. The zonal momentum...
