AbstractBased on nearly 4 year-long moored velocity measurements at 8 degrees N/127 degrees E and a high-resolution ocean model output, a significant 30-50-day variation in the subthermocline current east of Mindanao was identified for the first time in addition to the 60-80-day variation reported in previous studies. The 30-50-day variation is an important component and it explains considerable variance same as that of the 60-80-day variation. The 30-50-day variation is vertically coherent in the subthermocline current. The standard deviations of the 30-50-day variation in zonal and meridional directions are of comparable, and is about 4.5-5 cm/s. Eddy-tracking analysis indicated that ocean eddies originating from the North Equatorial Current (10 degrees N-11 degrees N) contribute to the 30-50-day and the 60-80-day variations. The 30-50-day eddies propagate faster than the 60-80-day eddies.
