Impact of the stratosphere on tropospheric climate change
Geophysical Research Letters, 2008 The atmospheric circulation response to CO2 doubling in various versions of an atmospheric general circulation model (AGCM) without a well‐resolved stratosphere (“low‐top” model), is compared to the response in a version of the same AGCM with a well ...

An Ozone-Modified Refractive Index for Vertically Propagating Planetary Waves [PDF]
, 2007 [1] An ozone-modified refractive index (OMRI) is derived for vertically propagating planetary waves using a mechanistic model that couples quasigeostrophic potential vorticity and ozone volume mixing ratio. The OMRI clarifies how wave-induced heating due

Stratospheric tropical warming event and its impact on the polar and tropical troposphere [PDF]
Atmospheric Chemistry and Physics, 2017 Stratosphere–troposphere coupling is investigated in relation to middle atmospheric subtropical jet (MASTJ) variations in boreal winter. An exceptional strengthening of the MASTJ occurred in association with a sudden equatorward shift of the ...

Signature of the stratosphere–troposphere coupling on recent record-breaking Antarctic sea-ice anomalies [PDF]
The Cryosphere, 2023 In February 2023, the sea-ice extent around Antarctica dropped to 1.79×106 km2, setting a satellite-era record low for the second straight year. Recent records stress the need for further research into the factors behind record-breaking Antarctic sea-ice

On the structural changes in the Brewer-Dobson circulation after 2000 [PDF]
, 2010 In this paper we present evidence that the observed increase in tropical upwelling after the year 2000 may be attributed to a change in the Brewer-Dobson circulation pattern.

The Effect of Solar Activity on Stratospheric Temperature Over Iraq for Period 1948-2014
Al-Mustansiriyah Journal of Science, 2022 Stratospheric temperature changes are very important for climate systems through atmospheric circulation and stratosphere-troposphere coupling. The relationship between solar modulation potential SMP as a measure of solar activity and variation of ...

Tropospheric eddy feedback to different stratospheric conditions in idealised baroclinic life cycles [PDF]
Weather and Climate Dynamics, 2021 A pronounced signature of stratosphere–troposphere coupling is a robust negative anomaly in the surface northern annular mode (NAM) following sudden stratospheric warming (SSW) events, consistent with an equatorward shift in the tropospheric jet.

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter
Weather and Climate Extremes, 2023 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.

Scaling of Eliassen‐Palm flux vectors
Atmospheric Science Letters, 2021 Eliassen‐Palm flux is one of the main diagnostics tools for wave propagation and wave‐mean flow interaction in atmospheric dynamics and in particular stratosphere‐troposphere coupling.
