This study examines the global climatic anomalies associated with the Southern Oscillation (SO) by analyzing temperature and precipitation data from several hundred stations worldwide. The research identifies significant signals for both the warm and cold extremes of the SO, with warm events generally showing opposite signals to cold events. The anomalies are consistent across different regions, confirming the biennial tendency of the SO over the Pacific and Indian oceans. The study also finds that climatic anomalies in the year preceding an SO event (year -1) tend to be opposite to those in the following year (year +1), indicating a modulation of the seasonal cycle. The analysis uses composite techniques to examine temperature and precipitation anomalies during various stages of the SO, from year -1 to year +1. The results highlight the strong correlation between sea surface temperature (SST) in the eastern equatorial Pacific and global temperature and precipitation patterns. The study concludes that while many identified signals are statistically significant, their inter-event variability limits their predictive value. However, the findings provide valuable insights into the global atmospheric and oceanic responses to the SO, contributing to a better understanding of the global climate system.This study examines the global climatic anomalies associated with the Southern Oscillation (SO) by analyzing temperature and precipitation data from several hundred stations worldwide.
