Two sets of simulations have been used, consisting in three atmosphere-only and three atmosphere-ocean coupled experiments, which are based on past, present and future conditions. The QBO influence on the extratropical circulation, formally known as the Holton-Tan effect, has also been assessed during boreal winter (DJF). Results show a notorious shortening of the QBO period and a clear weakening of the QBO amplitude under a warming climate in the coupled simulations; which do not show a significant impact on the Holton-Tan effect in the polar vortex.12 p.application/pdfengcc-by-nc-nd (c) Lacima, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Oscillació quasi biennalEstratosferaTreballs de fi de màsterQuasi-biennial oscillationStratosphereMaster's thesesinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
