  • Cyclone Factsheet UPDATE
    TROPICAL CYCLONES AND CLIMATE CHANGE: FACTSHEET CLIMATECOUNCIL.ORG.AU TROPICAL CYCLONES AND CLIMATE CHANGE: FACT SHEET KEY POINTS • Climate change is increasing the destructive power of tropical cyclones. o All weather events today, including tropical cyclones, are occurring in an atmosphere that is warmer, wetter, and more energetic than in the past. o It is likely that maximum windspeeds and the amount of rainfall associated with tropical cyclones is increasing. o Climate change may also be affecting many other aspects of tropical cyclone formation and behaviour, including the speed at which they intensify, the speed at which a system moves (known as translation speed), and how much strength is retained after reaching land – all factors that can render them more dangerous. o In addition, rising sea levels mean that the storm surges that accompany tropical cyclones are even more damaging. • While climate change may mean fewer tropical cyclones overall, those that do form can become more intense and costly. In other words, we are likely to see more of the really strong and destructive tropical cyclones. • A La Niña event brings an elevated tropical cyclone risk for Australia, as there are typically more tropical cyclones in the Australian region than during El Niño years. BACKGROUND Tropical cyclones, known as hurricanes in the North Atlantic and Northeast Pacific, typhoons in the Northwest Pacific, and simply as tropical cyclones in the South Pacific and Indian Oceans, are among the most destructive of extreme weather events. Many Pacific Island Countries, including Fiji, Vanuatu, Solomon Islands and Tonga, lie within the South Pacific cyclone basin.

  • The Bathurst Bay Hurricane: Media, Memory and Disaster
    The Bathurst Bay Hurricane: Media, Memory and Disaster Ian Bruce Townsend Bachelor of Arts (Communications) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2019 School of Historical and Philosophical Inquiry Abstract In 1899, one of the most powerful cyclones recorded struck the eastern coast of Cape York, Queensland, resulting in 298 known deaths, most of whom were foreign workers of the Thursday Island pearling fleets. Today, Australia’s deadliest cyclone is barely remembered nationally, although there is increasing interest internationally in the cyclone’s world record storm surge by scientists studying past cyclones to assess the risks of future disasters, particularly from a changing climate. The 1899 pearling fleet disaster, attributed by Queensland Government meteorologist Clement Wragge to a cyclone he named Mahina, has not until now been the subject of scholarly historical inquiry. This thesis examines the evidence, as well as the factors that influenced how the cyclone and its disaster have been remembered, reported, and studied. Personal and public archives were searched for references to, and evidence for, the event. A methodology was developed to test the credibility of documents and the evidence they contained, including the data of interest to science. Theories of narrative and memory were applied to those documents to show how and why evidence changed over time. Finally, the best evidence was used to reconstruct aspects of the event, including the fate of several communities, the cyclone’s track, and the elements that contributed to the internationally significant storm tide. The thesis concludes that powerful cultural narratives were responsible for the nation forgetting a disaster in which 96 percent of the victims were considered not to be citizens of the anticipated White Australia.

    Recovery of the Great Barrier Reef Dr David Bourne, James Cook University Hillary Smith, James Cook University May-September, 2018 PAGE 1 LETTER TO VOLUNTEERS Dear Earthwatch volunteers, Our team at James Cook University and Earthwatch Australia wish to thank you for the continued field support during our 12th and 13th field trip expeditions. Again with great weather conditions, this season has been especially successful in fulfilling our missions in the field. In February 2011, a severe tropical cyclone (Yasi) struck the coast of North Queensland and caused catastrophic damage to reefs in the study area around Orpheus Island located in the central sector of the Great Barrier Reef. In 2016 and 2017 the Great Barrier Reef was also hit by the largest bleaching events on recorded resulting in unprecedented coral mortality in some areas of the reef. Finally coral populations at the study sites have previously suffered from outbreaks of a coral disease, black- band disease (BBD). Our goals of the field work were; 1) monitor the recovery of coral populations extensively damaged following cyclone Yasi; 2) Assess the impacts of the bleaching events in 2017 and 2017 on these recovering populations; 3) study how coral disease outbreaks influence this reef recovery processes; 4) elucidate the microbial mechanisms of BBD; and 5) conduct pilot surveys of benthic cover for future algal removal research. We are grateful for the hard work of the Earthwatch volunteers during the field trips in 2018 and appreciated the fantastic sunny days that volunteers brought with them. Favourable conditions allowed us to efficiently collect coral data from all the study sites that we have been monitoring.

Firstly, I would like to thank my wife Marcella whose constant belief that I could accomplish this project, while she was learning to live with her own personal trauma at the same time, encouraged me to persevere with this thesis project when the tide of my own faith would ebb. I could not have come this far without her faith in me and her determination to journey with me on this path. I would also like to thank my supervisors, Professors Stephen Torre and Richard Landsdown, for their valuable support, constructive criticism and suggestions during the course of our work together.

Introduction The following information was taken from the Bureau of Meteorology (BOM) webpage: http://www.bom.gov.au/cyclone/history/yasi.shtml (see also Figure 1). Severe Tropical Cyclone Yasi began developing as a tropical low northwest of Fiji on 29 January 2011 and started tracking on a general westward track. The system quickly intensified to a cyclone category to the north of Vanuatu and was named Yasi at 10pm on 30 January by the Fijian Meteorological Service. Yasi maintained a westward track and rapidly intensified to a Category 2 by 10am on 31 January and then further to a Category 3 by 4pm on the same day. Yasi maintained Category 3 intensity for the next 24 hours before being upgraded to a Category 4 at 7pm on 1 February. During this time, Yasi started to take a more west-southwestward movement and began to accelerate towards the tropical Queensland coast.

Tropical cyclones (cyclones) are natural meteorological events which cannot be prevented. However, the combination of their impacts and those of other stressors — such as poor water quality, crown-of-thorns starfish predation and warm ocean temperatures — can permanently damage reefs if recovery time is insufficient. In the short term, management response to a particular tropical cyclone may be warranted to promote recovery if critical resources are affected. Over the long term, using modelling and field surveys to assess the impacts of individual tropical cyclones as they occur will ensure that management of the Great Barrier Reef represents world best practice. This Tropical Cyclone Risk and Impact Assessment Plan was first developed by the Great Barrier Reef Marine Park Authority (GBRMPA) in April 2011 after tropical cyclone Yasi (one of the largest category 5 cyclones in Australia’s recorded history) crossed the Great Barrier Reef near Mission Beach in North Queensland.
