Stratosphere-Troposphere Coupling and Global Warming [PDF]

, 2021
<p>The atmospheric circulation response to the anthropogenic increase of CO<sub>2</sub> is known to generally involve a number of pathways of change, often leading to contrasting responses, the so called “tug of wars”.

A critical comparison of stratosphere–troposphere coupling indices [PDF]

Quarterly Journal of the Royal Meteorological Society, 2009
AbstractAssessing stratosphere–troposphere coupling in observational data or model output requires a multi‐level index with high time resolution. Ideally, such an index would (1) represent spatial patterns in the troposphere that are most strongly coupled with stratospheric variability and (2) be robust and computationally feasible in both observations

Gravity waves as a mechanism of troposphere–stratosphere–mesosphere coupling during sudden stratospheric warming [PDF]

Atmospheric Chemistry and Physics
The propagation of gravity waves (GWs) and their role in the coupling of the troposphere–stratosphere–mesosphere atmospheric layers during sudden stratospheric warming (SSW) are studied. A standard set of hydrodynamic (HD) equations is used to derive the

Energetic Particle Forcing of the Northern Hemisphere winter stratosphere: Comparison to solar irradiance forcing

Frontiers in Physics, 2014
Variation in solar irradiance is considered an important factor in natural climate forcing. Variations in the solar UV in particular are now regarded as a major source of decadal variability in the stratosphere, influencing surface climate through ...

Stratosphere-troposphere coupling on subseasonal timescales

, 2021
Variability in the Arctic stratospheric polar vortex can significantly influence the behaviour and predictability of wintertime tropospheric weather conditions on subseasonal timescales (lead-times between 2 weeks and 2 months). This thesis improves our understanding of tropospheric processes leading to subseasonal stratospheric variability and how to ...

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 ...

Influence of Wintertime Polar Vortex Variation on the Climate over the North Pacific during Late Winter and Spring

Atmosphere, 2019
The effects of wintertime stratospheric polar vortex variation on the climate over the North Pacific Ocean during late winter and spring are analyzed using the National Centers for Environmental Predictions, version 2 (NCEP2) reanalysis dataset.

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 ...

Quantifying stratospheric biases and identifying their potential sources in subseasonal forecast systems [PDF]

Weather and Climate Dynamics, 2022
The stratosphere can be a source of predictability for surface weather on timescales of several weeks to months. However, the potential predictive skill gained from stratospheric variability can be limited by biases in the representation of stratospheric

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 ...
