Investigating the Response of Temperature and Salinity in the Agulhas Current Region to ENSO Events

The Agulhas Current is a critical component of global ocean circulation and has been observed to respond El Niño Southern Oscillation (ENSO) events via its temperature salinity signatures. In this research, we use sea surface (SSS) from the National Aeronautics Space Administration’s (NASA) Soil Moisture Active Passive (SMAP) satellite, (SST) observations Canadian Meteorological Centre (CMC), height (SSH) anomalies altimetry, Oceanic Index study SMAP satellite time period April 2015 through March 2020 (to observe full years study). We see warming high salinities after Niño, cooling fresher waters La Niña, stronger response than that salinity. About one year there entire region except at Antarctic Circumpolar Current. two event, an increase in along eastern coast Africa region. 2016 2018 Niñas, south Madagascar There are no major changes seen Current, but highly saline mass water west Indonesian Throughflow about Niña events. Wavelet coherence analysis finds SSS ENSO most strongly correlated Niña.
