Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which
large and rapid temperature increases in the winter polar stratosphere (∼ 10–50 km) are …

Sudden stratospheric warming (SSW) events are extreme atmospheric regimes which can
have a signature in surface weather up to 40 days after event onset in the stratosphere …

Sudden stratospheric warmings (SSWs) have been linked to surface temperature
anomalies, but how these connect to changes in the likelihood of specific weather extremes …

Every spring, the stratospheric polar vortex transitions from its westerly wintertime state to its
easterly summertime state due to seasonal changes in incoming solar radiation, an event …

Extreme weather events have significant consequences, dominating the impact of climate on
society. While high‐resolution weather models can forecast many types of extreme events …

Sudden stratospheric warmings (SSWs) can have major impact on surface wintertime
weather, especially at mid‐high latitudes. We do not yet have a complete understanding of …

The dominant pattern of Northern Hemisphere extratropical climate variability is the Northern
Annular Mode (NAM), which in wintertime represents the coupling of the stratospheric and …

Sudden stratospheric warmings (SSWs) are associated with episodes of extreme winter
weather, often leading to significant societal impacts. Using observations alone, it is hard to …

Sudden stratospheric warmings (SSWs) are key to understanding and predicting
subseasonal Northern Hemisphere winter climate variability. Here we study the uncertainty …

Impacts of sudden stratospheric warming (SSW) on three severe cold events (C1–C3) over
Northern Hemisphere in early 2021 were investigated using subseasonal‐to‐seasonal …
