Reinitializing Sea Surface Temperature in the Ensemble Intermediate Coupled Model for Improved Forecasts

The Ensemble Intermediate Coupled Model (EICM) is a model used for studying the El Niño-Southern Oscillation (ENSO) phenomenon in Pacific Ocean, which anomalies Sea Surface Temperature (SST) are observed. This research aims to implement Cressman improve SST forecasts. simulation considers two cases this work: control case and initialized case. These simulations using different inputs where differ terms of their resolution data source. method initialize with an analysis product based on satellite situ such as ships, buoys, Argo floats, 0.25 × degrees. results inclusion Initialized (CIEICM). Forecasting sea surface temperature was conducted both EICM CIEICM. show that calculation field from CIEICM more accurate than EICM. forecast initialization higher-resolution satellite-based at 6-month lead time improved root mean square deviation 0.794 0.808 correlation coefficient 0.630 0.611, compared directly low-resolution in-situ-based analysis.
