The El Nino-Southern Oscillation (ENSO) plays a key role in the interannual variability of the global climate. Its prediction and recognition has been a big challenge to the atmospheric and ocean science modeling community despite significant advances in understanding, improved models, and enhanced observational networks. The present study proposes a new approach by using the support vector machines (SVM) classification model of machine learning algorithm to identify and possible predict the future ENSO events. The daily sea surface temperature data in the Pacific Ocean from NOAA National Centers for Environmental Information (NCEI) is used as the training set, and each daily data in the training set is assigned an ENSO index as the primary indicator of ENSO events. The Principal component analysis (PCA) is used to decompose the training set in a set of successive orthogonal components (eigen maps) that explain a maximum amount of the variance and bring out the strong patterns. The test results show the great match between the true ENSO index and the predicted ENSO index as shown in the attached plot. The proposed method can also be used to other research areas such as cyclone and tornado pattern search.
