Category 1: Peer-reviewed literature

Major mid-winter stratospheric sudden warmings (SSWs) are the largest instance of wintertime variability in the Arctic stratosphere. Because SSWs are able to cause significant surface weather anomalies on intra-seasonal timescales…

Response of sea surface temperature to climate change and its influence on the wintertime polar vortex in chemistry-climate models SPARC Workshop Stratospheric Change and its Role in Climate Prediction (SHARP), Berlin, Germany, 16-19 February, 2016, 2016 (Ref: 15754)

Category 3: Verbal presentation

Future changes in the boreal polar vortex under a climate change scenario are still a matter of debate in the scientific community. For example, there is a lack of consensus among models about possible future changes in the frequency of major stratospheric warmings.

Future changes in Major Stratospheric Warmings in CCMI models American Meteorological Society 95th Annual Meeting, Phoenix, USA, 3-8 January 2015,, 2015 (Ref: 15434)

Ayarzagüena B.Langematz U.Polvani L.M.Abalichin J.Akiyoshi A.Klekociuk A.R.Michou M.Morgenstern O.Oman L.D.Shibata K.
Category 3: Verbal presentation

Major stratospheric warmings (MSWs) are one of the most important phenomena of wintertime Arctic stratospheric variability. They consist of a warming of the Arctic stratosphere and a deceleration of the polar night jet…
