description: Given a finite group scheme $\cG$ over an algebraically closed field $k$ of characteristic $\Char(k)=p>0$, we introduce new invariants for a $\cG$-module $M$ by associating certain morphisms $°^j_M : U_M \lra \Gr_d(M) \ \ (1\!\le\!j\!\le\! p\!-\!1)$ to $M$ that take values in Grassmannians of $M$. These maps are studied for two classes of finite algebraic groups, infinitesimal group schemes and elementary abelian group schemes. The maps associated to the so-called modules of constant $j$-rank have a well-defined degree ranging between $0$ and $j\rk^j(M)$, where $\rk^j(M)$ is the generic $j$-rank of $M$. The extreme values are attained when the module $M$ has the equal images property or the equal kernels property. We establish a formula linking the $j$-degrees of $M$ and its dual $M^\ast$. For a self-dual module $M$ of constant Jordan type this provides information concerning the indecomposable constituents of the pull-back $α^\ast(M)$ of $M$ along a $p$-point $α: k[X]/(X^p) \lra k\cG$.

description: Context. The elliptical galaxy NGC 3923 is surrounded by numerous stellar shells that are concentric arcs centered on the galactic core. They are very likely a result of a minor merger and they consist of stars in nearly radial orbits. For a given potential, the shell radii at a given time after the merger can be calculated and compared to observations. The Modified Newtonian Dynamics (MOND) is a theory that aims to solve the missing mass problem by modifying the laws of classical dynamics in the limit of small accelerations. Hernquist & Quinn(1987) claimed that the shell distribution of NGC 3923 contradicted MOND, but Milgrom(1988) found several substantial insufficiencies in their work. Aims. We test whether the observed shell distribution in NGC 3923 is consistent with MOND using the current observational knowledge of the shell number and positions and of the host galaxy surface brightness profile, which supersede the data available in the 1980s when the last (and negative) tests of MOND viability were performed on NGC 3923. Methods. Using the 3.6 um bandpass image of NGC 3923 from the Spitzer space telescope we construct the mass profile of the galaxy. The evolution of shell radii in MOND is then computed using analytical formulae. We use 27 currently observed shells and allow for their multi-generation formation, unlike the Hernquist & Quinn one-generation model that used the 18 shells known at the time. Results. Our model reproduces the observed shell radii with a maximum deviation of 5% for 25 out of 27 known shells while keeping a reasonable formation scenario. A multi-generation nature of the shell system, resulting from successive passages of the surviving core of the tidally disrupted dwarf galaxy, is one of key ingredients of our scenario supported by the extreme shell radial range. The 25 reproduced shells are interpreted as belonging to three generations.

description: We study different types of solitons of a generalized nonlinear Schrödinger equation (GNLSE) that models optical pulses traveling down an optical waveguide with quadratic as well as quartic dispersion. A traveling-wave ansatz transforms this partial differential equation into a fourth-order nonlinear ordinary differential equation (ODE) that is Hamiltonian and has two reversible symmetries. Homoclinic orbits of the ODE that connect the origin to itself represent solitons of the GNLSE, and this allows us to study the existence and organization of solitons with advanced numerical tools for the detection and continuation of connecting orbits. In this way, we establish the existence of connections from one periodic orbit to another, called PtoP connections. They give rise to families of homoclinic orbits to either of the two periodic orbits; in the GNLSE they correspond to generalized solitons with oscillating tails whose amplitude does not decay but reaches a nonzero limit. Moreover, PtoP connections can be found in the energy level of the origin, where connections between this equilibrium and a given periodic orbit, called EtoP connections, are known to organize families of solitons. As we show here, EtoP and PtoP cycles can be assembled into different types of heteroclinic cycles that give rise to additional families of homoclinic orbits to the origin. In the GNLSE, these correspond to multi-oscillation solitons that feature several episodes of different oscillations in between their decaying tails. As for solitons organized by EtoP connections only, multi-oscillation solitons are shown to be an integral part of the phenomenon of truncated homoclinic snaking.

description: Robertson DM, Diebel MW. 2020. Importance of accurately quantifying internal loading in developing phosphorus reduction strategies for a chain of shallow lakes. Lake Reserv Manage. XX:XXX–XXX. The Winnebago Pool is a chain of 4 shallow lakes in Wisconsin. Because of high external phosphorus (P) inputs to the lakes, the lakes became highly eutrophic, with much P contained in their sediments. In developing a total maximum daily load (TMDL) for these lakes, it is important to determine how their phosphorus concentrations should respond to changes in external P loading. In many TMDLs, internal P loading is assumed to be negligible or it is estimated based on sediment release rates and dissolved oxygen conditions in the lake, and each lake is considered independently. To evaluate these assumptions, internal P loading and external P loading were quantified by developing detailed P budgets for the Winnebago Pool chain of lakes. This information was then inputted into 2 eutrophication models (BATHTUB and Jensen models), which were used to simulate the steady-state and transient effects of various P reduction strategies. The importance of internal P loading varied among lakes, from being a minor source to representing almost 60% of the summer P input. Model results indicate that each lake responds to external P reductions, but internal loading can delay the lake responses, especially in the most downstream lake, Lake Winnebago, where internal P loading was most important to its summer P budget. Accurately quantifying net internal P loading and using this information in lake models are important in evaluating how large shallow lakes should respond to P reduction strategies, setting realistic expectations from watershed P reductions, and guiding TMDL efforts.

description: We present PYATB, a Python package designed for computing band structures and related properties of materials using the ab initio tight-binding Hamiltonian. The Hamiltonian is directly obtained after conducting self-consistent calculations with first-principles packages using numerical atomic orbital (NAO) bases, such as ABACUS. The package comprises three modules: Bands, Geometric, and Optical. In the Bands module, one can calculate essential properties of band structures, including the partial density of states (PDOS), fat bands, Fermi surfaces, and Weyl/Dirac points. The band unfolding method is utilized to obtain the energy band spectra of a supercell by projecting the electronic structure of the supercell onto the Brillouin zone of the primitive cell. With the Geometric module, one can compute the Berry phase and Berry curvature-related quantities, such as electric polarization, Wilson loops, Chern numbers, and anomalous Hall conductivities. The Optical module offers a range of optical property calculations, including optical conductivity and nonlinear optical responses, such as shift current and Berry curvature dipole.

description: We develop a nonlinear force-free field (NLFFF) extrapolation code based on the magnetohydrodynamic (MHD) relaxation method. We extend the classical MHD relaxation method in two important ways. First, we introduce an algorithm initially proposed by cite{2002JCoPh.175..645D} to effectively clean the numerical errors associated with $nabla cdot vec{B}$. Second, the multi-grid type method is implemented in our NLFFF to perform direct analysis of the high-resolution magnetogram data. As a result of these two implementations, we successfully extrapolated the high resolution force-free field introduced by cite{1990ApJ...352..343L} with better accuracy in a drastically shorter time. We also applied our extrapolation method to the MHD solution obtained from the flux-emergence simulation by cite{2012ApJ...748...53M}. We found that NLFFF extrapolation may be less effective for reproducing areas higher than a half-domain, where some magnetic loops are found in a state of continuous upward expansion. However, an inverse S shaped structure consisting of the sheared and twisted loops formed in the lower region can be captured well through our NLFFF extrapolation method. We further discuss how well these sheared and twisted fields are reconstructed by estimating the magnetic topology and twist quantitatively.

description: The PICOSEC Micromegas (MM) detector is a precise timing gaseous detector consisting of a Cherenkov radiator combined with a photocathode and a MM amplifying structure. A 100-channel non-resistive PICOSEC MM prototype with 10x10 cm^2 active area equipped with a Cesium Iodide (CsI) photocathode demonstrated a time resolution below 18 ps. The objective of this work is to improve the PICOSEC MM detector robustness aspects; i.e. integration of resistive MM and carbon-based photocathodes; while maintaining good time resolution. The PICOSEC MM prototypes have been tested in laboratory conditions and successfully characterised with 150 GeV/c muon beams at the CERN SPS H4 beam line. The excellent timing performance below 20 ps for an individual pad obtained with the 10x10 cm^2 area resistive PICOSEC MM of 20 MOhm/sq showed no significant time resolution degradation as a result of adding a resistive layer. A single-pad prototype equipped with a 12 nm thick Boron Carbide (B4C) photocathode presented a time resolution below 35 ps; opening up new possibilities for detectors with robust photocathodes. The results made the concept more suitable for the experiments in need of robust detectors with good time resolution.

description: We introduce a semi-parametric approach to ecological regression for disease mapping, based on modelling the regression M-quantiles of a Negative Binomial variable. The proposed method is robust to outliers in the model covariates, including those due to measurement error, and can account for both spatial heterogeneity and spatial clustering. A simulation experiment based on the well-known Scottish lip cancer data set is used to compare the M-quantile modelling approach and a random effects modelling approach for disease mapping. This suggests that the M-quantile approach leads to predicted relative risks with smaller root mean square error than standard disease mapping methods. The paper concludes with an illustrative application of the M-quantile approach, mapping low birth weight incidence data for English Local Authority Districts for the years 2005-2010.

description: Magnetohydrodynamic (MHD) waves are ubiquitously observed in the solar atmosphere. Kink waves are a type of transverse MHD waves in magnetic flux tubes that are damped due to resonant absorption. The theoretical study of kink MHD waves in solar flux tubes is usually based on the simplification that the transverse variation of density is confined to a nonuniform layer much thinner than the radius of the tube, i.e., the so-called thin boundary approximation. Here, we develop a general analytic method to compute the dispersion relation and the eigenfunctions of ideal MHD waves in pressureless flux tubes with transversely nonuniform layers of arbitrary thickness. Results for kink waves are produced and are compared with fully numerical resistive MHD eigenvalue computations in the limit of small resistivity. We find that the frequency and resonant damping rate are the same in both ideal and resistive cases. The actual results for thick nonuniform layers deviate from the behavior predicted in the thin boundary approximation and strongly depend on the shape of the nonuniform layer. The eigenfunctions in ideal MHD are very different from those in resistive MHD. The ideal eigenfunctions display a global character regardless of the thickness of the nonuniform layer, while the resistive eigenfunctions are localized around the resonance and are indistinguishable from those of ordinary resistive Alfvén modes. Consequently, the spatial distribution of wave energy in the ideal and resistive cases is dramatically different. This poses a fundamental theoretical problem with clear observational consequences.

New insights on the behaviour of solar wind protons and alphas in the Stream Interaction Region in solar cycle 23 and 24

description: Although the enhancements in the alpha-proton ratio in the solar wind (expressed as $A_{He} = N_a/N_p*100$) in the Interplanetary Coronal Mass Ejections (ICMEs) have been studied in the past, $A_{He}$ enhancements at the stream interface region received very little attention so far. In this letter, by extensively analyzing the stream interaction region (SIR) events observed in solar cycle 23 and 24, we show that the stream interface of alphas starts separating out from that of protons from the minimum of solar cycle 23. The population of alpha particles are enhanced compared to protons at higher angles between bulk velocity and local magnetic field (henceforth, bulk velocity angle) in the fast wind region of SIRs if the background solar wind is taken as reference. The analysis of differential velocities between alphas and protons also reveals that the faster alpha particles accumulate near the fast wind side of the stream interface region leading to enhancement of $A_{He}$. The investigation brings out, for the first time, the salient changes in $A_{He}$ in SIRs for the two solar cycles and highlight the importances of bulk velocity angle and differential velocity in the fast wind region for the changes in $A_{He}$ in SIRs.
Altruism and Agriculture: The Ethics of Fictional Farmyards
Creators: name: Oakes, Kate
Publisher: name: The Australian National University
Year: 2022

description: This Creative Writing thesis comprises a creative and a critical component. The critical component, "An Arrant Traitor to His Defenceless Sheep": Farmyard Ethics in the Fiction of Thomas Hardy, examines the work of this canonical Victorian author. Hardy's work is often characterised by biophilia, and the animal life represented in his fiction is complex, nuanced, and ideologically loaded. Scholars have long been fascinated by Hardy's animals and their meanings in his works (West, Kreilkamp, Cohn, Sumpter, Levine, Beer, Sherman, Carroll, Martell, Fischler). While wild creatures and domestic pets in Hardy's novels have received ample critical attention, livestock have been registered by only a few scholars. The thesis uses a theoretical approach from Animal Studies, an interdisciplinary project aimed at interrogating human-animal relations, as well as extensive existing research on Hardy's fiction. It asks how an author so invested in animal welfare depicts an industry so founded upon animal exploitation, which is fundamental to Hardy's landscape. To answer this question, the thesis examines three novels central to Hardy's oeuvre that are characterised by their agricultural content. These are Far from the Madding Crowd (1874), Tess of the d'Urbervilles (1891), and Jude the Obscure (1895). I argue that Hardy's depiction of livestock animals is best understood as displaying two competing discourses, one humanitarian in nature and the other utilitarian, and that the unreconciled contradictions of these competing discourses creates a lingering tension. This tension has the effect of creating a shocking and visceral experience of the farm which provokes further consideration of animal issues like carnism. Reading Hardy's novels in this way opens up understandings of Hardy's conceptions of human-animal relations and exposes the masterful literary techniques used in expressing them. The thesis also illuminates Victorian animal rights discourses, sets out their continuing implications today, and even more crucially, highlights the influential role that fiction can take in animal welfare discussions. The creative and critical components are united in their desire to explore how fiction can grapple with the inherent ethical paradoxes of traditional animal farming. Where Green Limbs Grow depicts a rural community centred around animal farming. In the fictional hamlet of Westhill, newcomer Charlotte watches her farmer neighbours naming their animals and also consuming them, assisting in the birth of calves and dragging them from their mothers, sees their gentleness and their duplicity. Charlotte struggles to reconcile these components of the farmer's role whilst simultaneously grappling with new realisations about her own animality.

description: Optical interferometry has been successful at achieving milliarcsecond resolution on bright stars. Imaging performance can improve greatly by increasing the number of baselines, which has motivated proposals to build large (~ 100 m) optical interferometers with tens to hundreds of telescopes. It is also desirable to adaptively correct atmospheric turbulence to obtain direct phased images of astrophysical sources. When a natural guide star is not available, we investigate the feasibility of using a modified laser-guide-star technique that is suitable for large diluted apertures. The method consists of using sub-sets of apertures to create an array of artificial stars in the sodium layer and collecting back-scattered light with the same sub-apertures. We present some numerical and laboratory simulations that quantify the requirements and sensitivity of the technique.

description: Star clusters have long been used to illuminate both stellar evolution and Galactic evolution. They also hold clues to the chemical and nucleosynthetic processes throughout the history of the Galaxy. We have taken high signal-to-noise, high-resolution spectra of 11 solar-type stars in the Praesepe open cluster to determine the chemical abundances of 16 elements: Li, C, O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Fe, Ni, Y, and Ba. We have determined Fe from Fe I and Fe II lines and find [Fe/H] = +0.12 $\pm$0.04. We find that Li decreases with temperature due to increasing Li depletion in cooler stars; it matches the Li-temperature pattern found in the Hyades. The [C/Fe] and [O/Fe] abundances are below solar and lower than the field star samples due to the younger age of Praesepe (0.7 Gyr) than the field stars. The alpha-elements, Mg, Si, Ca, and Ti, have solar ratios with respect to Fe, and are also lower than the field star samples. The Fe-peak elements, Cr and Ni, track Fe and have solar values. The neutron capture element [Y/Fe] is found to be solar, but [Ba/Fe] is enhanced relative to solar and to the field stars. Three Praesepe giants were studied by Carrera and Pancino; they are apparently enhanced in Na, Mg, and Ba relative to the Praesepe dwarfs. The Na enhancement may indicate proton-capture nucleosynthesis in the Ne -> Na cycling with dredge-up into the atmospheres of the red giants.

description: Drones have the potential to revolutionize power line inspection by increasing productivity, reducing inspection time, improving data quality, and eliminating the risks for human operators. Current state-of-the-art systems for power line inspection have two shortcomings: (i) control is decoupled from perception and needs accurate information about the location of the power lines and masts; (ii) obstacle avoidance is decoupled from the power line tracking, which results in poor tracking in the vicinity of the power masts, and, consequently, in decreased data quality for visual inspection. In this work, we propose a model predictive controller (MPC) that overcomes these limitations by tightly coupling perception and action. Our controller generates commands that maximize the visibility of the power lines while, at the same time, safely avoiding the power masts. For power line detection, we propose a lightweight learning-based detector that is trained only on synthetic data and is able to transfer zero-shot to real-world power line images. We validate our system in simulation and real-world experiments on a mock-up power line infrastructure. We release our code and datasets to the public.

description: Graphene electrodes provide a suitable alternative to metal contacts in molecular conduction nanojunctions. Here, we propose to use graphene electrodes as a platform for effective photon assisted tunneling through molecular conduction nanojunctions. We predict dramatic increasing currents evaluated at side-band energies $\sim n\hbarω$ ($n$ is a whole number) related to the modification of graphene gapless spectrum under the action of external electromagnetic field of frequency $ω$. A side benifit of using doped graphene electrodes is the polarization control of photocurrent related to the processes occurring either in the graphene electrodes or in the molecular bridge. The latter processes are accompanied by surface plasmon excitation in the graphene sheet that makes them more efficient. Our results illustrate the potential of graphene contacts in coherent control of photocurrent in molecular electronics, supporting the possibility of single-molecule devices.

description: We present a comprehensive study of graphene grown by chemical vapor deposition on copper single crystals with exposed (100), (110) and (111) faces. Direct examination of the as-grown graphene by Raman spectroscopy using a range of visible excitation energies and microRaman mapping shows distinct strain and doping levels for individual Cu surfaces. Comparison of results from Raman mapping with X-ray diffraction techniques and Atomic Force Microscopy shows it is neither the crystal quality nor the surface topography responsible for the specific strain and doping values, but it is the Cu lattice orientation itself. We also report an exceptionally narrow Raman 2D band width caused by the interaction between graphene and metallic substrate. The appearance of this extremely narrow 2D band with full-width-at-half maximum (FWHM) as low as 16 cm-1 is correlated with flat and undoped regions on the Cu(100) and (110) surfaces. The generally compressed (~ 0.3% of strain) and n-doped (Fermi level shift of ~250 meV) graphene on Cu(111) shows the 2D band FWHM minimum of ~20 cm-1. In contrast, graphene grown on Cu foil under the same conditions reflects the heterogeneity of the polycrystalline surface and its 2D band is accordingly broader with FWHM > 24 cm-1.

description: Through this thesis, I describe my field placement at Health Protection NSW (HPNSW) in fulfilment of the requirements of the Master of Philosophy in Applied Epidemiology (MAE). After spending much of my first year in COVID-19 pandemic response activities, the second year of my MAE was mainly based in the Communicable Diseases Branch (CDB) of HPNSW, as a member of the team responding to other notifiable conditions in NSW. My epidemiological study project focuses on these other notifiable conditions. In this project, I reviewed the surveillance data for a range of notifiable conditions, for changes in the epidemiology that may be attributable to the events of 2020, particularly the restriction of international travel. The findings showed a decrease in the incidence of most travel-related notifiable conditions in NSW, with the notable exception of tuberculosis. In light of the lifting of travel restrictions in late 2021, these findings were presented to a range of HPNSW staff, to inform planning for future surveillance strategies in NSW. My data analysis project was driven by the Environmental Health Branch of HPNSW, but with extensive input from both CDB and the medical entomologists at the Institute of Clinical Pathology and Medical Research (ICPMR), the state arboviral reference laboratory. I reviewed the last decade of data from the NSW Arbovirus Surveillance and Mosquito Monitoring Program (ASMMP), and the corresponding human notification data for Ross River virus (RRV) and Barmah Forest virus (BFV) infections. I attended a laboratory visit to the ICPMR Medical Entomology Laboratory, and a field visit to a mosquito trapping site at Sydney Olympic Park. I also assisted with the weekly EHB reporting of ASMMP data. In CDB, I was the main contact person for vector-borne diseases for the latter half of 2021. All these activities enabled me to ground the design and analysis of these data in real world context. The findings of the project, and recommendations for the ASMMP derived from these findings, were presented to stakeholders. These finding supported the continued use of trapped mosquito counts to inform human RRV and BFV risk, and indicated that in future analyses, it could be useful to include a time lag between mosquito numbers and human notifications, which had not previously been attempted in the analysis of these data in NSW.

description: We study the pion Distribution Amplitude (πDA) in the context of a nonlocal chiral quark model. The corresponding Lagrangian reproduces the phenomenological values of the pion mass and decay constant, as well as the momentum dependence of the quark propagator obtained in lattice calculations. It is found that the obtained πDA has two symmetric maxima, which arise from the new contributions generated by the nonlocal character of the interactions. This πDA is applied to leading order and next-to-leading order calculations of the pion-photon transition form factor. Implications of the results are discussed.

American Grand Strategy in the Middle East, 1972-2018: Toward a Neoclassical Realist Appraisal of Strategic Adjustment
Creators: name: Ricketts, Anthony
Publisher: name: The Australian National University
Year: 2018

description: How do we understand American strategic adjustment in the Middle East? In the discipline of strategic studies, answers to this question are regularly found within realist theoretical literature. The realist canon has long argued that the anarchic international system forces states to adopt "self-help" strategies for their survival. Systemic factors push and pull states in directions according to shifts in the global distribution of power. When one state acquires more economic and military power, realists argue, other states will balance against this rising power to restore the equilibrium. As a result, American strategic adjustment in the Middle East is regularly understood to have occurred in response to an alteration in the regional balance of power. This thesis agrees with part of this realist explanation. It acknowledges that the anarchical international system has socialised the United States to adopt balancing behaviour in the region. Yet the thesis builds on this realist assumption to argue unit-level variables are necessary to explain the various strategies the United States has deployed with respect to balancing the region. While not dismissing the importance of the international realm, it is interested in how ideologies, ideas, and interests interpret systemic factors to produce a distinct military strategic adjustment. Therefore, this thesis does not isolate systemic and unit-level variables, as realist scholarship advises, but instead positions domestic factors as the explanatory variable in America's strategic adjustment in the Middle East. Through the deployment of a neoclassical realist framework, this thesis identifies five distinct cycles of American strategy in the Middle East: (i) 1972 - 1979, offshore balancing; (ii) 1980 - 2000, selective engagement; (iii) 2001-2008, pre-emption; (iv) 2009-2016, retrenchment; and (v) 2017-2018, selective engagement. The independent variable that produced these five phases of adjustment are traced to the four traditions identified by Walter Russell Mead in his Special Providence: American Foreign Policy and How it Changed the World. Specifically, I suggest that: (i) the offshore balancing strategy has an affinity with the Hamiltonian tradition of integrating America into the global economy; (ii) the selective engagement strategy has its origins in the Jacksonian tradition of the protection of American security interests through the use of military force abroad; (iii) the strategy of pre-emption can be traced to the Wilsonian tradition of democracy building abroad; and (iv) the strategy of retrenchment is connected to the Jeffersonian tradition of safeguarding American liberty and democracy, through the rejection of foreign entanglements.

description: We have measured the quasiparticle generation-recombination (GR) noise in aluminium lumped element kinetic inductors with a wide range of detector volumes at various temperatures. The basic detector consists of meandering inductor and interdigitated capacitor fingers. The inductor volume is varied from 2 to 153 μm^{3} by changing the inductor width and length to maintain a constant inductance. We started with measuring the power spectrum density (PSD) of the detectors frequency noise which is a function of GR noise and we clearly observed the spectrum roll off at 10 kHz which corresponds to the quasiparticle lifetime. Using data from a temperature sweep of the resonator frequency we convert the frequency fluctuation to quasiparticle fluctuation and observe its strong dependence on detector volume: detectors with smaller volume display less quasiparticle noise amplitude. Meanwhile we observe a saturated quasiparticle density at low temperature from all detectors as the quasiparticle life time τqp approaches a constant value at low temperature.

description: The ANAIS (Annual Modulation with NaI(Tl) Scintillators) experiment aims at the confirmation of the DAMA/LIBRA signal using the same target and technique at the Canfranc Underground Laboratory. 250 kg of ultrapure NaI(Tl) crystals will be used as a target, divided into 20 modules, each coupled to two photomultipliers. Two NaI(Tl) crystals of 12.5 kg each, grown by Alpha Spectra from a powder having a potassium level under the limit of our analytical techniques, form the ANAIS-25 set-up. The background contributions are being carefully studied and preliminary results are presented: their natural potassium content in the bulk has been quantified, as well as the uranium and thorium radioactive chains presence in the bulk through the discrimination of the corresponding alpha events by PSA, and due to the fast commissioning, the contribution from cosmogenic activated isotopes is clearly identified and their decay observed along the first months of data taking. Following the procedures established with ANAIS-0 and previous prototypes, bulk NaI(Tl) scintillation events selection and light collection efficiency have been also studied in ANAIS-25.

Climate Change and Atmospheric Factors in Predicting Fire Season Severity
Creators: name: Taylor, Rachel Elizabeth
Publisher: name: The Australian National University
Year: 2018

description: Weather systems and climate drivers affect temperature and precipitation and are clearly associated with regional fire regimes; however, these links are poorly understood in many areas. In this thesis the relationships between fire season severity in the period 1950-2017 in seven locations in southern Australia, and synoptic-scale atmospheric variables and large-scale climate drivers are investigated. These relationships are found to be spatially coherent, with south-eastern and south-western Australia generally being affected by similar weather systems and climate drivers. Using the random forest technique – one not often used in climate science – the identified relationships are used to develop predictive tests for fire season severity which can be employed two to six months prior to the fire season. These predictive tests differ between the earliest years of the dataset and the most recent. This suggests changing influences of climate variables on fire season severity in each location. These changes are consistent with the expected effects of climate change, such as the intensification of climate drivers and of the subtropical ridge in the Australian region. This is the first study to produce a reliable tool for fire danger prediction in southern Australia with seasonal lead times. Such a tool could prove useful for fire agencies in planning and preparing for fire seasons in the future.
