Short summary
A reverse seasonal ocean circulation in the Panama Bight has been assessed using 27 years of absolute dynamical topography. The mean circulation in the eastern tropical Pacific (east of 100° W) is analyzed from the mean dynamic topography (MDT) and a self-organizing-map analysis. Small differences are observed west of ~82° W. In the Panama Bight, MDT shows the cyclonic circulation when the Panama surface wind jet dominates the region. We assess ENSO effects on seasonal circulation.
