Tropical tropospheric responses to a sudden stratospheric warming (SSW) event that
occurred over Antarctica in September 2019 have been investigated by conducting a series …

Antarctic sea ice expansion and recession are asymmetric in nature, with regional and
temporal variations. The decade-long overall increase in the Antarctic sea ice extent (SIE) …

The effect of stratospheric ozone depletion on the Amundsen Sea Low (ASL), a
climatological low‐pressure center important for the climate of West Antarctica, remains …

Abstract In the Southern Hemisphere, variability of the stratospheric polar vortex is an
important driver of surface climate. In this study, we explore the influence of weakening and …

While weakening of the boreal polar vortex may be caused by autumnal Arctic sea ice loss,
less is known about the interannual influence of Antarctic sea ice on stratosphere …

The discovery of causal structures behind a phenomenon under investigation has been at
the heart of scientific inquiry since the beginning. Randomized control trials, the gold …

Abstract The Amundsen Sea low (ASL) is one of the key components of the Antarctic surface
climate. Here, we assess the subseasonal to seasonal (S2S) predictive skill of the ASL in …

This study aims to compare the ground-based Brewer spectrophotometer total ozone
column measurements with the Dobson spectrophotometer and various satellite overpass …

To highlight the impact of satellite measurements, a comparison between the Japanese 55‐
year reanalysis (JRA‐55) and its equivalent without the assimilation of satellite observations …

Der stratosphärische Polarwirbel ist in der Lage, bodennahe Bedingungen in der
erweiterten Wintersaison erheblich zu beeinflussen. Induziert durch meridionale …
