Pełny tekst źródłaThe study examines the response of an atmospheric general circulation model (OCM) to a reduction in Antarctic sea-ice extent during summer and winter, with emphasis on non-polar and southern African climates. Following an evaluation of the OCM, the control and perturbation simulations are analysed. The controls are forced by prescribed, observed sea surface temperatures (SSTs) and sea-ice extents, while in the perturbation simulations sea-ice is reduced and replaced with SSTs. The introduced anomalies are derived from an algorithm based on observed ice variability. The simulations are restarts of an AMIP (Atmospheric Model Intercomparison Project) configured simulation, and two summers (1979/80 and 1984185) and two winters (1980 and 1985) have been selected for the study. Three replicates have been performed for each time period for both the control and perturbation conditions.

Pełny tekst źródłaLes changements de concentration d'ozone stratosphérique ont été déjà reliés aux changements de la circulation dans l'hémisphère sud (HS). Ce travail examine les tendances dans la précipitation et l'évaporation pendant les 20ième et 21ième siècles, dans des simulations produites par des modèles climatique couplés qui participent au Climate Model Intercomparison Project 3 (CMIP3). Le but est de déterminer si l'ozone stratosphérique influence le cycle hydrologique et la précipitation extrême aux latitudes extra-tropicales de l'HS, pendant l'été austral en particulier. Dix-neuf modèles sont utilisés, où 10 d'entre eux incorporent l'épuisement (le rétablissement) d'ozone au 20ième (21ième) siècle et les neuf autres prescrivent simplement l'ozone climatologique (du 20ième siècle) pendant le passé et le futur. Les tendances des moyennes saisonnières de précipitation dominent les changements de l'évaporation moins la précipitation, alors c'est cette variable qui est examinée plus en détail. Pour le 20ième siècle, il y a une augmentation (diminution) de précipitation significative en été aux latitudes subarctique (latitudes moyennes) dans les modèles avec l'épuisement d'ozone comparé à ceux avec l'ozone climatologique. En contraste, pour le 21ième siècle, les changements de précipitation sont considérablement plus grands dans les modèles sans le rétablissement d'ozone que dans les modèles avec le rétablissement d`ozone. Pour l'hiver austral, quand l'ozone est inactif, il n'y a pas de différences entre les deux groupes de modèles. Ces résultats suggèrent que la diminution et rétablissement d'ozone dans l'Antarctique a des implications considérables pour le changement de climat hydrologique dans l'HS hors tropique, une conclusion atteinte dans d'autres travaux. En plus, on trouve que l'ozone stratosphérique affecte principalement la fréquence des évènements de précipitation légère (1–10 mm jour^-1), ce qui indique qu'une augmentation de la précipitation moyenne correspond à une augmentation du nombre de jours de précipitation légère, plutôt que d'évènements extrêmes. Les implications de ces conclusions pour le climat à la surface ainsi que pour les changements de circulation dans l'océan de l'HS sont discutés.

In some experiments in which idealized general circulation models (GCMS) are used to study the tropospheric response to stratospheric perturbations, the tropospheric response is much stronger and longer-lived compared to observations (e.g., Polvani and Kushner 2002, Kushner and Polvani 2004). Chan and Plumb (2009) found that those experiments which exhibited particularly long tropospheric decorrelation times (and, by the fluctuation dissipation theorem, much stronger annular mode responses) were marked by bimodality in the distribution of the latitude of surface zonal-mean zonal winds. Here, ERA-Interim and NCEP/NCAR reanalysis data are used to establish if this bimodality exists in the Southern Hemisphere (SH) near-surface winds, which would predict the existence of an additional mode of tropospheric variability exhibiting stronger and longer-lived responses than what has previously been observed. Histograms of the latitudinal position of maximum near-surface zonal-mean zonal winds turn up no convincing evidence of jet bimodality, although they do reveal an interesting - but probably spurious trimodality in the NCEP/NCAR June-August 850-hPa distribution of jet latitude. A climatology of wintertime zonal winds reveals that there is a time-mean split jet over the South Pacific Ocean; furthermore, empirical orthogonal function analysis reveals that, over the South Pacific, the dominant mode of wintertime zonal wind variability is a splitting and un splitting of the jet. Ultimately, both the climatological split jet and its variability are determined not to be evidence of jet bimodality. The temporal trends in the distribution of near-surface jet latitude are also examined. Stratospheric ozone depletion has been implicated in surface circulation changes in the SH high latitudes; one of these changes has been a poleward shift of the jet in austral summer. In this thesis, it is found that a poleward shift of the December-February distribution of jet latitude has taken place from the pre-ozone-hole to ozone-hole eras, consistent with previous findings. The novel result is that there has also been a poleward shift of this distribution in May, which is consistent with a secondary maximum in ozone depletion near the tropopause in April-May as observed by other authors (Thompson et al. 2011), and would imply the occurrence of troposphere-stratosphere coupling in late fall. An in-depth investigation of these May zonal wind trends will be pursued in future work.

Pełny tekst źródłaThis thesis characterises and discusses two continuous coastal Southern Hemispheric (SH) atmospheric radon (222Rn) signals. Large-scale atmospheric circulation patterns are important components of the climate system implicated in driving catastrophic events such as extreme droughts and mega-wildfires and radon measurements at coastal sites provide valuable information on interactions of terrestrial and oceanic air masses on regional to hemispheric scales. The main collaborating SH atmospheric observatories in this study are located at Cape Grim (CGO, Tasmania, 1992-2017) and Cape Point (CPO, South Africa, 1999-2017). The radon signal from a high-altitude remote island oceanic site in the Northern Hemisphere Mauna Loa Observatory (MLO, Hawaii, 2004-2015) is also incorporated for comparison purposes. The CGO radon signal is the longest and most sensitive in current existence. A variety of statistical, spectral, trend, back-trajectory and trajectory density methods are utilized in this study to illuminate features of the datasets on multiple scales. Strongly skewed radon distributions occur, with a large number of events falling into a compact range of low values (corresponding to marine air-masses) and a smaller number of events spread over a wide range of high-radon values (continental air-masses). Making use of Fast Fourier Transform power spectral analysis, prominent periodicities are identified on diurnal and annual scales. Inter-annual variations in seasonal and diurnal radon and meteorological characteristics, indicating changes in the continental/oceanic atmospheric mixing state, are evident especially during the period from 2012 to 2017, perhaps associated with the strong El-Niño southern oscillation centred on 2015. A slow but systematic decline in CGO and CPO radon levels is evident over the dataset, associated with fewer continental and more marine air-masses impacting the coastal stations. The long-term trends observed in the atmospheric radon signal may indicate changes in SH circulation patterns over time, perhaps associated with climate change effects.

Pełny tekst źródłaThe zonally averaged meridional eddy heat and momentum transports and the associated baroclinic and barotropic energy conversions are also examined. The distributions of the transports on the vertical plane agree well with observations. When compared to the observed summer 1979 distributions, some quantitative differences remain: the vertical structure of the heat transport is too baroclinic, while the momentum transport tends to be too weak. The baroclinic and barotropic conversions all show a medium scale wave signal. The time evolution of the Richardson number of the mean flow suggests that the medium scale wave is due to a finite amplitude baroclinic instability.

Pełny tekst źródłaEin globales mechanistisches Zirkulationsmodell wird verwendet um die Dynamik der Mesosphäre und unteren Thermosphäre im Südwinter zu simulieren. Das Modell beinhaltet eine Schwerewellenparametrisierung die durch eine vorgeschriebene Schwerewellenverteilung in der oberen Troposphäre angetrieben wird. In der Standardkonfiguration besteht diese aus einer einfachen zonal gemittelten Verteilung mit größeren Amplituden im Winter als im Sommer. Wir ersetzen diese Verteilung durch eine realistischere, die auf der beobachteten globalen Verteilung der potentiellen Energie von Schwerewellen basiert und auf die gleiche global gemittelte Amplitude normiert wird. Das Modellexperiment zeigt, dass die neue Schwerewellenverteilung zu schwächeren zonalen Winden in der Mesosphäre, einer Verschiebung des meridionalen Jets nach unten, verstärkten Abwinden in der Mesosphäre mittlerer und höherer Breiten im Winter, und einer Erwärmung der polaren Winterstratopause führt.
