Refugee Review Tribunal AUSTRALIA RRT RESEARCH RESPONSE Research Response Number: CHN31098 Country: China Date: 8 January 2007 Keywords: China – Taiwan Strait – 2006 Military exercises – Typhoons This response was prepared by the Country Research Section of the Refugee Review Tribunal (RRT) after researching publicly accessible information currently available to the RRT within time constraints. This response is not, and does not purport to be, conclusive as to the merit of any particular claim to refugee status or asylum. Questions 1. Is there corroborating information about military manoeuvres and exercises in Pingtan? 2. Is there any information specifically about the military exercise there in July 2006? 3. Is there any information about “Army day” on 1 August 2006? 4. What are the aquatic farming/fishing activities carried out in that area? 5. Has there been pollution following military exercises along the Taiwan Strait? 6. The delegate makes reference to independent information that indicates that from May until August 2006 China particularly the eastern coast was hit by a succession of storms and typhoons. The last one being the hardest to hit China in 50 years. Could I have information about this please? The delegate refers to typhoon Prapiroon. What information is available about that typhoon? 7. The delegate was of the view that military exercises would not be organised in typhoon season, particularly such a bad one. Is there any information to assist? RESPONSE 1. Is there corroborating information about military manoeuvres and exercises in Pingtan? 2. Is there any information specifically about the military exercise there in July 2006? There is a minor naval base in Pingtan and military manoeuvres are regularly held in the Taiwan Strait where Pingtan in located, especially in the June to August period. -
Toward the Establishment of a Disaster Conscious Society
Special Feature Consecutive Disasters --Toward the Establishment of a Disaster Conscious Society-- In 2018, many disasters occurred consecutively in various parts of Japan, including earthquakes, heavy rains, and typhoons. In particular, the earthquake that hit the northern part of Osaka Prefecture on June 18, the Heavy Rain Event of July 2018 centered on West Japan starting June 28, Typhoons Jebi (1821) and Trami (1824), and the earthquake that stroke the eastern Iburi region, Hokkaido Prefecture on September 6 caused damage to a wide area throughout Japan. The damage from the disaster was further extended due to other disaster that occurred subsequently in the same areas. The consecutive occurrence of major disasters highlighted the importance of disaster prevention, disaster mitigation, and building national resilience, which will lead to preparing for natural disasters and protecting people’s lives and assets. In order to continue to maintain and improve Japan’s DRR measures into the future, it is necessary to build a "disaster conscious society" where each member of society has an awareness and a sense of responsibility for protecting their own life. The “Special Feature” of the Reiwa Era’s first White Paper on Disaster Management covers major disasters that occurred during the last year of the Heisei era. Chapter 1, Section 1 gives an overview of those that caused especially extensive damage among a series of major disasters that occurred in 2018, while also looking back at response measures taken by the government. Chapter 1, Section 2 and Chapter 2 discuss the outline of disaster prevention and mitigation measures and national resilience initiatives that the government as a whole will promote over the next years based on the lessons learned from the major disasters in 2018. -

Gaining from Losses: Using Disaster Loss Data As a Tool for Appraising Natural Disaster Policy

IRB protocol #: 11-0029 iii Mohleji, Shalini (Ph.D., Environmental Studies) Gaining from Losses: Using Disaster Loss Data as a Tool for Appraising Natural Disaster Policy Thesis directed by Dr. Roger Pielke Jr. ABSTRACT This dissertation capitalizes on an opportunity, untapped until now, to utilize data on disaster losses to appraise natural disaster policy. Through a set of three distinct studies, I use data on economic losses caused by natural disasters in order to analyze trends in disaster severity and answer important disaster policy questions. The first study reconciles the apparent disconnect between (a) claims that global disaster losses are increasing due to anthropogenic climate change and (b) studies that find regional losses are increasing due to socioeconomic factors. I assess climate change and global disaster severity through regional analyses derived by disaggregating global loss data into their regional components. -

Deadly bushfires destroy hundreds of homes in Australia’s New South Wales Windstorm Christian moved across western and northern Europe, bringing hurricane-force wind gusts and torrential rains to several countries. At least 18 people were killed and dozens more were injured. The heaviest damage was sustained in the United Kingdom, France, Belgium, the Netherlands and Scandinavia, where a peak wind gust of 195 kph (120 mph) was recorded in Denmark. More than 1.2 million power outages were recorded and travel was severely disrupted throughout the continent. Reports from European insurers suggest that payouts are likely to breach EUR1.0 billion (USD1.35 billion). Total economic losses will be even higher. Christian becomes the costliest European windstorm since WS Xynthia in 2010. Cyclone Phailin became the strongest system to make landfall in India since 1999, coming ashore in the eastern state of Odisha. At least 46 people were killed. Tremendous rains, an estimated 3.5-meter (11.0-foot) storm surge, and powerful winds led to catastrophic damage to more than 430,000 homes and 668,000 hectares (1.65 million) acres of cropland. -

Tropical Cyclogenesis Associated with Rossby Wave Energy Dispersion of a Preexisting Typhoon
VOLUME 63 JOURNAL OF THE ATMOSPHERIC SCIENCES MAY 2006 Tropical Cyclogenesis Associated with Rossby Wave Energy Dispersion of a Preexisting Typhoon. Part I: Satellite Data Analyses* TIM LI AND BING FU Department of Meteorology, and International Pacific Research Center, University of Hawaii at Manoa, Honolulu, Hawaii (Manuscript submitted 20 September 2004, in final form 7 June 2005) ABSTRACT The structure and evolution characteristics of Rossby wave trains induced by tropical cyclone (TC) energy dispersion are revealed based on the Quick Scatterometer (QuikSCAT) and Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) data. Among 34 cyclogenesis cases analyzed in the western North Pacific during 2000–01 typhoon seasons, six cases are associated with the Rossby wave energy dispersion of a preexisting TC. The wave trains are oriented in a northwest–southeast direction, with alternating cyclonic and anticyclonic vorticity circulation. A typical wavelength of the wave train is about 2500 km. The TC genesis is observed in the cyclonic circulation region of the wave train, possibly through a scale contraction process. The satellite data analyses reveal that not all TCs have a Rossby wave train in their wakes. The occur- rence of the Rossby wave train depends to a certain extent on the TC intensity and the background flow. Whether or not a Rossby wave train can finally lead to cyclogenesis depends on large-scale dynamic and thermodynamic conditions related to both the change of the seasonal mean state and the phase of the tropical intraseasonal oscillation. Stronger low-level convergence and cyclonic vorticity, weaker vertical shear, and greater midtropospheric moisture are among the favorable large-scale conditions.
