Global average cooling and Northern Hemisphere winter warming are well-known climatic responses to the June 15, 1991 eruption of the Mount Pinatubo volcano in the Philippines. Here we investigate the Southern Hemisphere response. Using National Centers for Environmental Prediction/National Center for Atmospheric Research Reanalysis, European Centre for Medium-Range Weather Forecasting Reanalysis, and simulations with the National Aeronautics and Space Administration Goddard Institute for Space Studies ModelE climate model, we find that, in contrast to the Northern Hemisphere, there were no strong significant anomalies in atmospheric circulation in the Southern Hemisphere. We examined 50 mb and 500 mb circulation patterns, as well as the Southern Hemisphere Annular Mode index, and found no consistent significant anomalies associated with the volcanic eruption, or the previous large volcanic eruptions of the past 50 years, the 1963 Agung and 1982 El Chichón eruptions. The few anomalies that occurred after Pinatubo are consistent with patterns found during an El Niño event, which took place that same year.
