The dynamical evolution of Sudden Stratospheric Warmings of the Arctic winters in the past decade 2011–2021

Abstract

Article Highlights Major warmings (MWs) of the past decade occurred mostly in January and then in February. A decreasing trend in the occurrence of MWs in the past decade, 0.36 MWs/winter. The warming occurrences in the stratosphere make lower ozone depletion. A positive correlation exists between lower stratospheric temperature and total ozone.
