Extreme stratospheric wave activity as harbingers of cold events over North America [PDF]
Communications Earth & Environment, 2023 Extreme cold events over North America such as the February 2021 cold wave have been suggested to be linked to stratospheric polar vortex stretching. However, it is not resolved how robustly and on which timescales the stratosphere contributes to the ...

Satellite Reentry Predictions During Sudden Stratospheric Warmings
Space WeatherPrediction of uncontrolled satellite reentry time and trajectory are essential to avoid damages to human being and properties over land. Reentry time and trajectory are largely controlled by aerodynamic drag and mass neutral density below 200 km. In this

Origins of multi-decadal variability in sudden stratospheric warmings [PDF]
Weather and Climate Dynamics, 2021 Sudden stratospheric warmings (SSWs) are major disruptions of the Northern Hemisphere (NH) stratospheric polar vortex and occur on average approximately six times per decade in observation-based records.

Stratospheric wave driving events as an alternative to sudden stratospheric warmings [PDF]
Weather and Climate Dynamics, 2022 Natural variations in the strength of the northern stratospheric polar vortex, so-called polar vortex events, help to improve subseasonal-to-seasonal (S2S) predictions of winter climate.

Notes on the correlation between sudden stratospheric warmings and solar activity [PDF]
Annales Geophysicae, 2019 A correlation between solar activity and normalized occurrence rate of sudden stratospheric warmings (SSWs) has been found. As a proxy for solar activity, the 10.7 cm solar radio flux has been used.

The Simplified Chemistry-Dynamical Model (SCDM V1.0) [PDF]
Geoscientific Model Development, 2021 Recent observational and modeling studies show that variations of stratospheric ozone and the resulting interaction between ozone and the stratospheric circulation play an important role in surface weather and climate.
