ENSO and non‐ENSO induced charging and discharging of the equatorial Pacific

TWC modes. Results indicate that the oceanic evolution for both modes is consistent with wind stress induced verticallyintegrated, meridional mass transport into and out of the equatorial Pacific—i.e. a charging and discharging of the equatorial Pacific—despite having distinctly different wind stress anomaly patterns. The process-based similarity between these two modes of tropical Pacific wind stress variability suggests that both can produce a charging/discharging of the equatorial Pacific, however one (the ENSO mode) represents part of the ENSO cycle itself and the other (the TWC mode) represents a separate forcing mechanism of that cycle.
