Limited surface impacts of the January 2021 sudden stratospheric warming [PDF]
Subseasonal weather prediction can reduce economic disruption and loss of life, especially during “windows of opportunity” when noteworthy events in the Earth system are followed by characteristic weather patterns.

Oceanic fronts shape hemispheric contrasts in polar stratospheric extremes [PDF]
Sudden Stratospheric Warmings (SSWs) and Polar Stratospheric Clouds (PSCs) exhibit striking inter-hemispheric asymmetries: SSWs are frequent in the Arctic but rare in the Antarctic, while PSCs are more persistent in the Antarctic.

Stratospheric impacts on Eurasian soil moisture on subseasonal timescales [PDF]
Sudden stratospheric warming (SSW) events and soil moisture are both key sources of subseasonal-to-seasonal predictability, raising the possibility that SSWs could enhance hydroclimate predictability through soil moisture.

Local and remote response of ozone to Arctic stratospheric circulation extremes [PDF]
Intense natural circulation variability associated with stratospheric sudden warmings, vortex intensifications, and final warmings is a typical feature of the winter Arctic stratosphere.

The role of wave–wave interactions in sudden stratospheric warming formation [PDF]
The effects of wave–wave interactions on sudden stratospheric warming formation are investigated using an idealized atmospheric general circulation model, in which tropospheric heating perturbations of zonal wave numbers 1 and 2 are used to produce ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter
Using the ERA5 reanalysis, sea surface temperature, sea ice observations, and the real-time multivariate Madden-Julian Oscillation (MJO) index, the evolution of the stratospheric extreme circulation in the winter of 2022/2023 is explored.

Influences of Sudden Stratospheric Warming Events on Tropopause Based on GNSS Radio Occultation Data
Sudden Stratospheric Warming (SSW) events have a strong impact on the tropospheric weather and climate. Past researchers have carried out extensive studies investigating the theories of interactions between the stratosphere and the troposphere.
