El Niño-Southern Oscillation (ENSO) is a climate pattern in the Pacific Ocean that has two phases: El Niño (warm/wet phase) and La Niña (cold/dry phase). Because the temperature of the water during these events changes, it can have consequences on fisheries in South America and weather across the globe, with extreme events such as flooding and droughts often affecting South America, Indonesia and Australia.

We have been experiencing La Niña conditions for the last 2 and a half years. The last strong El Niño event occurred in 2015/2016 and a weak El Niño event was also experienced during the winter of 2018/2019.

Sea surface height (SSH) data from the TOPEX/Poseidon, Jason and Sentinel-6 Michael Freilich missions along with satellite sea surface temperature (SST) data help us study and understand the complex interactions between the ocean and the atmosphere that affect global weather and ....
