Abstract:
Abstract The sea surface temperature inter-hemispheric dipole (SSTID) is an important variability mode of global SST anomalies, characterized by an anti-phase variation of SST between the two hemispheres. In this study, the decadal variation of the northern hemisphere summer monsoon (NHSM) is found to be strongly regulated by the SSTID, with positive (negative) phases of the SSTID corresponding to the strengthening (weakening) of NHSM. Both observation and SST-forced atmospheric model simulations suggest that the SSTID related thermal forcing modulates the NHSM by causing planetary-scale atmospheric circulation adjustments. Positive SSTID events lead to coherent increase (decrease) of surface air temperature over the entire northern (southern) hemisphere, increasing the inter-hemispheric thermal contrast (ITC). As sea level pressure changes are just opposite to air temperature, the increase of ITC enhances the inter-hemispheric pressure gradient (southern hemisphere minus northern hemisphere), leading to the strengthening of summer monsoonal circulation and the increase of monsoon rainfall in the northern hemisphere.

Abstract:
Aims. Sunspot activity is often hemispherically asymmetric, and during the Maunder minimum, activity was almost completely limited to one hemisphere. In this work, we use surface flux simulation to study how magnetic activity limited only to the southern hemisphere affects the long-term evolution of the photospheric magnetic field in both hemispheres. The key question is whether sunspot activity in one hemisphere is enough to reverse the polarity of polar fields in both hemispheres. Methods. We simulated the evolution of the photospheric magnetic field from 1978 to 2016 using the observed active regions of the southern hemisphere as input. We studied the flow of magnetic flux across the equator and its subsequent motion towards the northern pole. We also tested how the simulated magnetic field is changed when the activity of the southern hemisphere is reduced. Results. We find that activity in the southern hemisphere is enough to reverse the polarity of polar fields in both hemispheres by the cross-equatorial transport of magnetic flux. About 1% of the flux emerging in the southern hemisphere is transported across the equator, but only 0.1%–0.2% reaches high latitudes to reverse and regenerate a weak polar field in the northern hemisphere. The polarity reversals in the northern hemisphere are delayed compared to the southern hemisphere, leading to a quadrupole Sun lasting for several years.

Abstract:
Abstract The Kodaikanal Observatory has provided long-term synoptic observations of chromospheric activities in the Ca ii K line (393.34 nm) since 1907. This article investigates temporal and periodic variations of the hemispheric Ca–K-index time series in the low-latitude zone (±40°), utilizing the recently digitized photographic plates of Ca–K images from the Kodaikanal Observatory for the period of 1907–1980. We find that the temporal evolution of the Ca–K index differs from one hemisphere to another, with the solar cycle peaking at different times in the opposite hemisphere, except for cycles 14, 15, and 21, when the phase difference between the two hemispheres was not significant. The monthly averaged data show a higher activity in the northern hemisphere during solar cycles 15, 16, 18, 19, and 20, and in the southern hemisphere during cycles 14, 17, and 21. We notice an exponentially decaying distribution for each hemisphere’s Ca–K index and the whole solar disk. We explored different midterm periodicities of the measured Ca–K index using the wavelet technique, including Rieger-type and quasi-biennial oscillations on different timescales present in the time series. We find a clear manifestation of the Waldmeier effect (stronger cycles rise faster than the weaker ones) in both the hemispheres separately and the whole disk in the data. Finally, we have found the presence of the Gnevyshev gap (time interval between two cycle maxmima) in both the hemispheric data during cycles 15 to 20. Possible interpretations of our findings are discussed with the help of existing theoretical models and observations.

Abstract:
Abstract Studying the interaction between solar flares and sunspot groups (SGs) is crucial for understanding and predicting solar activity. We examined the distribution, correlation, and flaring rates in the northern and southern hemispheres to reveal the relationship between different classes of soft X-ray (SXR) flares and different magnetic classifications of SGs. We discovered a significant north–south asymmetry in SXR flares and SG distribution over Solar Cycles (SC) 21–25. In the rising phase of SC24, the northern hemisphere’s activity is significantly excessive. In the declining phase of SC24, the southern hemisphere’s activity becomes significantly excessive. The total numbers of various SXR flares and SGs vary between the northern and southern hemispheres over the solar cycle. B-class flares are negatively correlated with all SGs at maximum but positively correlated at minimum. C-class flares correlate best with α and β SGs. M-class flares correlate best with β γ δ and β SGs. X-class flares correlate highest with β γ δ SGs. The flaring rate of each flare class is lowest for α SGs and highest for β γ δ SGs. The flaring rates are higher in the southern hemisphere than in the northern hemisphere. Our results demonstrate that solar flares originate from different sources of solar active regions; the high-energy flares tend to be caused by more complex magnetic fields.

Abstract:
Challenging Minisatellite Payload (CHAMP) satellite magnetic data are used to investigate the latitudinal variation of the storm-time meso-scale field-aligned currents by defining a new metric called the FAC range. Three major geomagnetic storm events are considered. Alongside SymH, the possible contributions from solar wind dynamic pressure and interplanetary magnetic field (IMF) BZ are also investigated. The results show that the new metric predicts the latitudinal variation of FACs better than previous studies. As expected, the equatorward expansion and poleward retreat are observed during the storm main phase and recovery phase respectively. The equatorward shift is prominent on the northern duskside, at ~58° coinciding with the minimum SymH and dayside at ~59° compared to dawnside and nightside respectively. The latitudinal shift of FAC range is better correlated to IMF BZ in northern hemisphere dusk-dawn magnetic local time (MLT) sectors than in southern hemisphere. The FAC range latitudinal shifts responds better to dynamic pressure in the duskside northern hemisphere and dawnside southern hemisphere than in southern hemisphere dusk sector and northern hemisphere dawn sector respectively. FAC range exhibits a good correlation with dynamic pressure in the dayside (nightside) southern (northern) hemispheres depicting possible electrodynamic similarity at day-night MLT sectors in the opposite hemispheres.

AbstractBecause of insurmountable problems associated with absolute dating, the non-literate cultures of the Southern Hemisphere can contribute little to Applied Historical Astronomy, although Maori traditions document a possible supernova dating to the period 1000-1770AD. In contrast, the abundant nineteenth century solar, planetary, cometary and stellar observational data provided by Southern Hemisphere professional and amateur observatories can serve as an invaluable mine of information for present-day astronomers seeking to incorporate historical data in their investigations.

Byrne, Nicholas. "Deterministic models of Southern Hemisphere circulation variability." Thesis, University of Reading, 2017. http://centaur.reading.ac.uk/74253/.

Full text
Abstract:
Statistical models of atmospheric variability typically attempt to account for deterministic seasonal variations by constructing a long-term average for each day or month of the year. Year-to-year variability can then be treated as some form of stochastic process about this long-term average. In general, the stochastic processes are assumed to be statistically stationary (invariant under time translation). However, for a non-linear system such as the Earth’s atmosphere, multiple seasonal evolutions may be possible for the same external forcing. In the presence of such a multiplicity of solutions, the identification of a seasonal cycle with a long-term average may not be the optimal procedure. Previous research has suggested that multiple evolutions of the seasonal cycle of the Southern Hemisphere mid-latitude circulation may be possible. The central goal of this thesis is to build on this work and to present evidence for different seasonal evolutions of the Southern Hemisphere mid-latitude circulation. This evidence is initially presented by highlighting a low-frequency peak in an aspect of the Southern Hemisphere mid-latitude circulation that is viewed as a harmonic of the annual cycle (quasi-two year). Statistically stationary models of variability about a long-term average are argued to be unable to account for the presence of this harmonic. Following this, an alternative model of circulation variability is proposed that explicitly references various stages of the seasonal cycle in a deterministic manner. In particular, explicit reference is made to the downward shift and to the final breakdown of the stratospheric polar vortex. A re-interpretation of several previous results in the literature including Southern Annular Mode persistence timescales, Southern Hemisphere mid-latitude climate change and the semi-annual oscillation of the mid-latitude jet is subsequently presented using this alternative perspective.

Abstract:
Data from a number of sources are used to examine the climatology of the southern hemisphere middle atmosphere. The stratospheric data used are winds and higher order quantities derived from stratospheric analyses provided by the U.S. National Meterological Center and the British Meteorological Office. Mesospheric winds are used from a number of years of continuous partial reflection radar observations at four southern hemisphere sites. A comparison of the stratospheric analyses is used to highlight the regions of inadequacy in the data, and to assess its reliability. A three year zonal mean climatology of the stratosphere is provided, and compared on an individual monthly basis with a time mean mesospheric climatology. This comparison highlights the importance of interannual variability in both the stratosphere and mesosphere, and emphasizes the mesospheric dependance on the stratospheric state below. Wave motions are traced propagating through the stratosphere and tentatively identified in the mesospheric winds. One particular wave, the four day wave is examined in detail, and shown to exist on occasion in both the stratosphere and mesosphere. Some suggestions for further work are presented, with respect to both data comparisons and stratosphere-mesosphere interactions.

Abstract:
This thesis details observations of three Southern hemisphere blazars PKS 2155-304 PKS 2005-489 and PKS 0548-322 using the University of Durham Mark 6 Telescope between 1996 and 1999. The nature of blazars and the physical processes responsible for very high energy emission are also discussed. A signal above 700 GeV was observed from PKS 2155-304 between 1996 and 1997 but not in 1998 and 1999. One plausible explanation for this is a reduction in sensitivity of the Mark 6.Evidence for variability of high energy emission from PKS 2155-304 was search for but no firm conclusion was reached. Upper limits to emission from PKS 2005-489 and PKS 0548-322 were determined. Gamma ray observations for all three objects were tested for correlation with near simultaneous 2-10 keV X-ray emission (taken using the ASM onboard RXTE). No strong evidence for correlation was found. It is worth noting however that gamma ray emission from PKS 2155-304 was detected when the X-ray emission was greatest. No constraints could be made on models of gamma ray production from blazars. No models were excluded. Future observations with the new generation of gamma ray telescopes such as H.E.S.S. and CANGAROO will allow more detailed investigation of these objects and many others and their variability while multiwavelength observations will determine the nature of the acceleration processes at work.

Abstract:
The work contained in this thesis is toward producing an objective cyclone climatology of the extra-tropical regions of the Southern Hemisphere using observational data. The data identified as being the most appropriate for this task was the high resolution multi-spectral imagery produced by the Advanced Very High Resolution Radiometer (AVHRR) on board the National Oceanographic and Atmospheric Administration (NOAA) series of polar-orbiting satellites. A series of algorithms are presented to perform the automatic detection and tracking of cyclones in the Southern Hemisphere. Cloud detection was performed using a number of spectral and textural measures. Individual cloud objects were segmented using thresholding techniques. These cloud objects were pre-processed using an image normalisation algorithm to create an image (feature vector) which was invariant to rotation, translation, scaling and skew. Identification and tracking of cyclones was performed by finding the maximum cross-correlation between the normalised target images and a set of pre-defined normalised templates. Problems with automatically distinguishing between cloud and the surface near Antarctica still remain, and subsequently segmentation of the imagery into individual cloud objects was limited to certain cases. Identification of cyclones by matching with the pre-defined normalised templates was also shown to have only very limited ability to distinguish between cyclone cloud objects and non-cloud objects. Tracking of the cyclones once they have been manually identified and measured was shown to be promising, with the algorithm successfully tracking the cyclone in 16 out of 22 pairs of satellite images taken from 4 case studies of real Southern Hemisphere cyclones. Limitations of the tracking scheme were identified and improvements have been suggested.

Abstract:
Lake deposits are widespread throughout the Phanerozoic rock record and have long intrigued geologists and paleobiologists in search of natural resources or fossil biota. Low-energy lacustrine depositional environments, characterized by relatively rapid sediment influx rates and shallow zones of bioturbation, likewise produce highly-resolved archives of climate and ecosystems evolution. This dissertation describes four studies that use lake sediments for Quaternary environmental analysis. In East Africa, many decades of prior study provided the critical framework necessary for in-depth paleoenvironmental research at Lake Tanganyika (3° - 9°S). Seismic stratigraphic analysis integrated with radiocarbon-dated sediment cores from the Kalya horst and platform document a dramatic lake level lowstand prior to ~106 ka and a minor, short-lived regression during the Last Glacial Maximum (32 - 14 ka). Paleobathymetric maps reveal that Lake Tanganyika remains a large, connected water body even during episodes of extreme drought, which has implications for local and regional fauna. Over shorter timescales, geochronological, taphonomic and sedimentological analyses of shell beds around Kigoma (central Lake Tanganyika) document three distinct facies-types that are time-averaged over the latest Holocene. Lake level fluctuations associated with the termination of the Little Ice Age (~ 16th century CE) and subsequent encrustation played a key role in shell bed formation and persistence along high-energy littoral platforms, which has implications for structuring specialized communities of benthic fauna. In central South America (18° - 22°S), we studied the limnogeology of small lakes in the Puna and the Pantanal. Analyses of these sites were undertaken to: 1) ascertain how the lakes act as depositional basins; 2) assess sedimentation rates; and 3) construct limnogeological databases to guide future interpretations of ancient sediment cores. At Laguna de los Pozuelos (Argentine Puna), linear sedimentation rates approach 0.14 cm*y⁻¹ in the playa-lake center, and litho- and organo-facies development are dominantly controlled by basin hydrology, climate and biological feedbacks (both nutrient cycling and bioturbation) from waterbirds. At Lagoas Gaíva, Mandioré and Vermelha (Brazilian Pantanal), short-lived radioisotopes indicate uninterrupted depositional rates of 0.11 - 0.24 cm*y⁻¹, and hydrochemical and depositional patterns respond sensitively to changes in the seasonal flooding cycle of the Upper Paraguay River.

Abstract:
Microbial biogeography is being increasingly more studied, both in terms of genetic divisions and 'ecotype' variation. This thesis investigates the regional (100-1000s km) and local (10s m) distribution and diversity of microorganisms around hydrothermal vents and seamounts at the East Scotia Ridge and the Southwest Indian Ridge. Microbial communities were characterized using Illumina dye sequencing to de- termine taxon richness and diversity and flow cytometry to obtain cell counts. In addition I investigated the physicochemical environment (nutrients, organic carbon, salinity and temperature) in which the microorganisms persist. Typical deep-sea microorganisms were abundant at vents and below the euphotic zone on the seamounts. The surface layer of the seamounts contained typical open-ocean photoautotrophic organisms. Microbial communities were correlated to or- ganic carbon on both hydrothermal vents and seamounts. With microorganisms possi- bly having a large influence on carbon sequestration into the deep-sea from hydrothermal vents. On a local scale the hydrothermal vents had a relatively higher abundance of chemosynthetic Epsilonproteobacteria and the Gammaproteobacteria family SUP05, which were closely correlated to the redox potential in the vent effluent. This was prominent in both plumes from the East Scotia Ridge and the Southwest Indian Ridge, which also had distinct microbial community structures. Across the Southwest Indian Ocean the microbial communities were firstly segregated by depth. However, on a regional scale their physical environment primarily divided the microbial communities into three biological regimes the sub-tropical, con- vergence zone and the sub-Antarctic. The microbial community structure and biogeography is influenced by steep environmental gradients, displaying a distance-decay relationship between sampling locations. With environmental conditions persisting at different scales, from local (10s m) around the hydrothermal vents to regional (100-1000 km) between the seamounts, driving the microbial community patterns. The same horizontal and vertical patterns for microorganisms and metazoans points to fundamental differences throughout all parts of the ecosystem/food web.

Abstract:
This thesis examines relationships that formed between US Transcendentalism and the Southern Hemisphere in the nineteenth century. It argues that the works of Ralph Waldo Emerson, Walt Whitman and Henry David Thoreau are relevant to the literary histories of regions including Latin America, Southern Africa and Australasia, and that this fact has been inadequately addressed by criticism. The introduction serves to situate this claim within ongoing debates in fields such as American Studies and World Literature. I contend that the inclusion of Southern Hemispheric literature within these discussions has the potential to enrich our interpretations of both US and world literary texts, particularly by enabling new approaches to be taken to long-standing, transnational questions of race, settler colonialism, globalization and Romantic nationalism. Each chapter centres on a different continental region in the Southern Hemisphere. In each, North American literary perceptions of that region are put into dialogue with nineteenth-century Southern Hemispheric responses to US Transcendentalism. The first chapter is devoted to Latin America; it concerns Edward and Alexander Everett, Sophia Peabody, Mary Mann, Domingo Faustino Sarmiento and José Martí. The second chapter focuses on South Africa in the late colonial period and highlights aspects of the thought and work of figures such as Olive Schreiner, Jan Smuts and Mahatma Gandhi. The final chapter considers Australia and the Pacific Islands. It begins with a discussion of the US philosopher Josiah Royce’s tour of Australasia and, thereafter, gives an account of Australian poetry’s response to Transcendentalism. Four poets are included in this section: Charles Harpur, Henry Kendall, William Gay and Bernard O’Dowd. The chapter concludes by drawing parallels between Charles Warren Stoddard’s correspondence with Whitman, his writings about the Pacific Islands and the strains of Primitivism that can be identified in Transcendentalist texts more generally.

Abstract:
To date, more than 300 planets orbiting stars other than our sun have been discovered using a range of observing techniques, with new discoveries occuring monthly. The work in this thesis focused on the detection of exoplanets using the transit method. Planets orbiting close to their host stars have a roughly 10 per cent chance of eclipsing (transiting) the star, with Jupiter?sized planets causing a one per cent dip in the flux of the star over a few hours. A wealth of orbital and physical information on the system can be extracted from these systems, including the planet density which is essential in constraining models of planetary formation. To detect these types of planets requires monitoring tens of thousands of stars over a period of months. To accomplish this, we conduct a wide-field survey using the 0.5-meter Automated Patrol Telescope (APT) at Siding Spring Observatory (SSO) in NSW, Australia. Once candidates were selected from the data?set, selection criteria were applied to separate the likely planet candidates from the false?positives. For this thesis, the methods and instrumentation used in attaining data and selecting planet candidates are discussed, as well as the results and analysis of the planet candidates selected from star fields observed from 2004?2007. Of the 65 planet candidates initially selected from the 25 target fields observed, only two were consistent with a planet transit. These candidates were later determined to be eclipsing binary stars based on follow up observations using the 40-inch telescope, 2.3-m telescope, and the 3.9-m Anglo-Australian Telescope, all located at SSO. Additionally, two planet candidates from the SuperWASP-North consortium were observed on the 40-inch telescope. Both proved to be eclipsing binary stars. While no planets were found, our search methods and results are consistent with successful transit surveys targeting similar fields with stars in a similar magnitude range and using similar methods.

Full text
Abstract:
The 15-16 June 1991 eruption of Mount Pinatubo delivered approximately 20 million metric tons of SO2 to the stratosphere. This is about three times the estimate for El Chichon (Bluth et al., 1992). While El Chichon's volcanic plume was confined mostly to the northern hemisphere, the SO2plume from Mount Pinatubo straddled the equator resulting in a more symmetrical global distribution of the H2SO4-H2O aerosol that results from the photochemical conversion of the SO2. Dutton and Christy (1992) find that the average Mount Pinatubo aerosol cloud as measured at two southern and two northern hemisphere sites exceeds the El Chichon aerosol optical depth for the first 10 months by about 70%. This is consistent with the extra SO2 loading and more uniform dispersal of the plume between hemispheres. They found the global and northern hemispheric temperatures of the lower troposphere to be 0.4 and 0.7° C below normal, respectively, by June 1992. This is consistent, thus far, with the predictions of Hansen et al. (1992).

Full text
Abstract:
Tetepare, an island in the Western Province of the Solomon Islands, is the largest uninhabited tropical island in the Southern Hemisphere. Tetepare has a largely intact wilderness, with remarkable biodiversity of globally significant conservation importance. This case study explores the biodiversity of Tetepare and efforts to maintain Tetepare as “the last wild island.” In response to threats by the extractive logging industry, the landowners of the island – Solomon Islanders descended from Tetepare’s original inhabitants - formed what is today known as the Tetepare Descendants’ Association (TDA), an organization that manages and conserves the island and its resources. TDA members receive benefits through a community conservation agreement (CCA): in return for conserving the land and rejecting all commercial exploitative industries, members receive benefits including scholarships, sustainable livelihood development, and employment opportunities. Tetepare’s conservation serves as an example of landowners successfully leveraging their natural inheritance to sustainably meet the economic needs of their communities without sacrificing the natural heritage of future generations.
