  • Understanding the role of high-latitude volcanic eruption in altering ENSO state (en gras, caractère 14)Very few studies are currently available in investigating the role of high-latitude eruptions on climate and specifically on the El Nino – Southern Oscillation (ENSO). It has been shown that large multi-stage (up to 8 month long) Northern Hemisphere eruptions in the high-latitudes during summer are able to significantly affect ENSO [Pausata et al., 2015, 2016]. However, very little is known regarding of other types of high-latitude eruptions such as short-live but very explosive as the case of Katmai – Alaska in 1912 or the role of the season.
    In this project the master student will analyze a large set of ensemble members performed with the Norwegian Earth System Model in which different types of high-latitude volcanic eruptions are simulated both in summer and winter as well as in the Northern and Southern Hemisphere. The student will investigate the ENSO response to the different type of eruptions and time of the year. The student will be encouraged to perform his/her own set of sensitivity experiments if needed. This project will allow the master student to get acquainted with climate model output as well as investigating the dynamics of one of the major mode of climate variability, i.e. ENSO.

  • Volcanic eruption impact on ocean circulation (en gras, caractère 14)Only in the last decade the impact of volcanic eruption on ocean circulation has been considered [Gleckler et al., 2006; Pausata et al., 2015; Swingedouw et al., 2015]. Therefore only recently the attention has been posed on potential long-term influence (decades) of volcanic eruptions beyond the classical residence time of the volcanic aerosol in the stratosphere (2-3 years). In this project the master student will use a large set of ensemble members performed with the Norwegian Earth System Model in which different volcanic eruptions have been simulated from tropical to high-latitude and in different seasons. The student will investigate the changes in the Atlantic Meridional Overturning Circulation (AMOC) associated to the different type of volcanic eruptions. The student will try to understand which are the most effective eruptions in altering the AMOC and investigate the mechanisms behind it. The student will be encouraged to perform his/her own set of sensitivity experiments if needed. This project will allow the master student to get acquainted with climate model output as well as investigating the dynamics of one of the major mode of climate variability, i.e. ENSO.
