Strong polar vortex favoured intense Northern European storminess in February 2022 [PDF]
Communications Earth & EnvironmentFebruary 2022 was an unusually stormy month over Northern Europe, including three extratropical cyclones impacting the United Kingdom and Ireland within a single week. The month also experienced an exceptionally strong stratospheric polar vortex; however,

Quasi-2D and 3D phase-field simulation studies of polar vortex domain structures for high-density domain engineering [PDF]
Scientific ReportsPhase-field simulations were performed on the polar vortex array structure appearing in the SrTiO3/PbTiO3/SrTiO3 heterostructure to investigate the Kittel law relationship (w ∝ d 1/2) between the vortex array period (w) and the PbTiO3 ferroelectric layer

On the pattern of interannual polar vortex–ozone co-variability during northern hemispheric winter [PDF]
Atmospheric Chemistry and Physics, 2023 Stratospheric ozone is important for both stratospheric and surface climate. In the lower stratosphere during winter, its variability is governed primarily by transport dynamics induced by wave–mean flow interactions. In this work, we analyze interannual
