![]() The link between volcanism and ENSO has been vigorously debated since it was first proposed 10. A causal relationship between large eruptions and ENSO would be important for evaluating climate models’ sensitivity to volcanic forcing, as well as assessing the risk of geoengineering solar radiation management schemes that emulate the stratospheric sulfate aerosol loading characteristic of large explosive eruptions 9. In particular, explosive volcanism may inject large amounts of sulfate aerosols into the atmosphere, abruptly reducing incoming shortwave radiation and affecting the subsequent global ocean-atmosphere climate variability for several years 8. ![]() ![]() Skillful prediction of the ENSO cycle, including its phase and amplitude, is therefore key to the successful forecasting of worldwide meteorological and oceanographic conditions at sub-seasonal to seasonal scales.Įxternal forcing has the potential to affect ENSO variability 4, 5, 6, 7. ENSO influences weather conditions not only in the tropical Pacific 2, but also globally through atmospheric teleconnections 3. The El Niño-Southern Oscillation (ENSO), the quasi-periodic alternation of warm and cold phases of the tropical Pacific ocean-atmosphere system, is the leading source of global interannual climate variability 1. ![]()
