| Abstract | Sea surface temperature (SST) variability in the western half of the Niño 4 region (Niño-4W), bounded by 160°E−175°W and 5°S–5°N, has a significant impact on weather and the marine environment of the Indo-Pacific. It exhibits significant negative skewness, with the strong penetration of the cold tongue into the western Pacific during strong La Niñas but a more muted response during El Niños. Zonal advection plays a dominant role in driving Niño-4W SST cooling during the strong La Niña events; vertical processes also contribute, with air-sea heat fluxes providing weak negative feedback. Advection also plays a key role in driving the Niño-4W SST warming, which is not always in sync with El Niño events. Among the advection terms, the advection of mean temperature by zonal velocity anomalies, or zonal advective feedback, plays a key role during the development phase of the warm and cold events. Strong negative air-sea heat flux anomalies during the development of warm events are linked to the negative SST skewness in the Niño-4W region. |
