Large volcanic eruptions affect the climate by injecting sulphur dioxide gas into the stratosphere which is converted to sulphate aerosols. These aerosols have the power to warm the stratosphere, cooling the troposphere by reflecting solar radiation. Since the Pinatubo eruption in 1991, which resulted in a global cooling of 0.4◦C, observations have shown that the stratosphere has been regularly impacted by volcanic eruptions of moderate magnitude on a hemispheric scale, but that these events have been less well documented in the tropics. During our research, we carried out simulations by the global model WACCM-CARMA, including chemical and microphysical cycles of Sulphur to study the variability of stratospheric aerosol content in the tropi...
