Abstract

The Cromwell Current flows eastward along the equator, and its characteristics are well understood in the Central Pacific. On the other hand, in the Eastern Pacific, especially during an ENSO (El Niño Southern Oscillation) event, further research is necessary, being the primary motivation for this study. The information provided by the Copernicus database was analyzed during the period between 1993 to 2017. The maximum speed of the current for each of the meridians 170 ° W, 140 ° W, 110 ° W and 86 ° W served to determine changes in its evolution during ENSO events. We observed that there were no optimal correlations with the Cromwell Current through cross-correlation with the Oceanic Niño Index (ONI) and the El Niño-ICEN Coastal Index. However, we found a pattern of ascending pulses before extreme ENSOs from 1997-1998 and 2015-2016. A considerable decrease in the anomalies of the Cromwell Current was observed during the maximum peaks.
