Stratwarm Effects in the Ionospheric D Region Wind Field [PDF]
An analysis is made of the wind field structure in the strato-thermosphere over Eastern Siberia during the winter stratwarms of 1975-1977. It is found that coupling between dynamical processes in the stratosphere and lower thermosphere is effected ...

Modelling the descent of nitric oxide during the elevated stratopause event of January 2013 [PDF]
Using simulations with a whole-atmosphere chemistry-climate model nudged by meteorological analyses, global satellite observations of nitrogen oxide (NO) and water vapour by the Sub-Millimetre Radiometer instrument (SMR), of temperature by the Microwave ...

Abstract Increased atmospheric CO2 affects climate through radiative and physiological forcing, but their specific roles in the transient changes in future potential evapotranspiration (PET) and dryness/wetness remain unclear. Using simulations from seven Earth System Models of the Coupled Model Intercomparison Project Phase 6, we quantify the ...

Development of algorithms for using satellite meteorological data sets to study global transport of stratospheric aerosols and ozone [PDF]
The utilization of stratospheric aerosol and ozone measurements obtained from the NASA developed SAM II and SAGE satellite instruments were investigated for their global scale transports.

Vortex splitting on a planetary scale in the stratosphere by cyclogenesis on a subplanetary scale in the troposphere [PDF]
It is hypothesized that a splitting of the stratospheric polar vortex and a sudden warming can result when the polar vortex is elongated and a closed cyclonic circulation develops on a subplanetary scale in the troposphere beneath one of its tips.

While mesospheric temperature anomalies associated with Sudden Stratospheric Warmings (SSWs) have been observed extensively in the polar regions, observations of these anomalies at midlatitudes are sparse.

Air quality and radiative impacts of downward-propagating sudden stratospheric warmings (SSWs) [PDF]
Sudden stratospheric warmings (SSWs) are abrupt disturbances to the Northern Hemisphere wintertime stratospheric polar vortex that can lead to pronounced regional changes in surface temperature and precipitation.

Enhancements of gravity wave amplitudes at midlatitudes during sudden stratospheric warmings in 2008 [PDF]
. Two minor and one major stratospheric warming happened in January and February 2008 when the polar vortex was shifted toward midlatitudes. The analysis of temperature profiles from radiosondes in Payerne (Switzerland) during this period reveals an ...

The importance of time-varying forcing for QBO modulation of the atmospheric 11 year solar cycle signal [PDF]
We present results from three multidecadal sensitivity experiments with time-varying solar cycle and quasi-biennial oscillation (QBO) forcings using National Center for Atmospheric Research's Whole Atmosphere Community Climate Model (WACCM3.1). The model

Stratospheric Impacts on Weather Regimes Following the 2018 and 2019 Sudden Stratospheric Warmings
Major disruptions of the stratospheric polar vortex can improve subseasonal forecast skill for surface climate, as negative North Atlantic Oscillation‐like (NAO−) states can follow sudden stratospheric warmings (SSWs).
