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 ...

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 ...

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.

Issues in Stratosphere-troposphere Coupling.
Journal of the Meteorological Society of Japan. Ser. II, 2002 An overview is given of current issues concerning the coupling between the stratosphere and troposphere. The tropopause region, more generally the upper troposphere/lower stratosphere, is the region of direct contact where exchange of material takes place.

Climatic variability of the stratosphere-troposphere coupling during the last decades [PDF]
Вестник КРАУНЦ. Физико-математические науки, 2021 В данной работе показано, как изменялось взаимодействие между тропосферой и стратосферой в последние десятилетия. Также оценено влияние таких явлений, как квазидвухлетнее колебание (КДК) на данное взаимодействие. Для этого было проанализировано распространение планетарных волн в атмосфере с использованием трехмерных потоков волновой активности ...

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction
International Journal of Chemical Kinetics, EarlyView.ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.
