Global Catastrophe Review – 2015
GC BRIEFING An Update from GC Analytics© March 2016 GLOBAL CATASTROPHE REVIEW – 2015 The year 2015 was a quiet one in terms of global significant insured losses, which totaled around USD 30.5 billion. Insured losses were below the 10-year and 5-year moving averages of around USD 49.7 billion and USD 62.6 billion, respectively (see Figures 1 and 2). Last year marked the lowest total insured catastrophe losses since 2009 and well below the USD 126 billion seen in 2011. 1 The most impactful event of 2015 was the Port of Tianjin, China explosions in August, rendering estimated insured losses between USD 1.6 and USD 3.3 billion, according to the Guy Carpenter report following the event, with a December estimate from Swiss Re of at least USD 2 billion. The series of winter storms and record cold of the eastern United States resulted in an estimated USD 2.1 billion of insured losses, whereas in Europe, storms Desmond, Eva and Frank in December 2015 are expected to render losses exceeding USD 1.6 billion. Other impactful events were the damaging wildfires in the western United States, severe flood events in the Southern Plains and Carolinas and Typhoon Goni affecting Japan, the Philippines and the Korea Peninsula, all with estimated insured losses exceeding USD 1 billion. The year 2015 marked one of the strongest El Niño periods on record, characterized by warm waters in the east Pacific tropics. This was associated with record-setting tropical cyclone activity in the North Pacific basin, but relative quiet in the North Atlantic.

This study developed a fast storm surge ensemble prediction method based on TC track probability forecasting and searching optimization of a numerical scenario database (SONSD). In a case study of the Fujian Province coast (China), a storm surge scenario database was established using numerical simulations generated by 93 150 hypothetical TCs. In a GIS-based visualization system, a single surge forecast representing 2562 distinct typhoon tracks and the occurrence probability of overflow of seawalls along the coast could be achieved in 1–2 min. Application to the cases of Typhoon Soudelor (2015) and Typhoon Maria (2018) demonstrated that the proposed method is feasible and effective. Storm surge calculated by SONSD had excellent agreement with numerical model results (i.e., mean MAE and RMSE: 7.1 and 10.7 cm, respectively, correlation coefficient: .0.9).

NASA Satellites Analyze Typhoon Soudelor Moving Toward Taiwan 5 August 2015
NASA satellites analyze Typhoon Soudelor moving toward Taiwan 5 August 2015 mission core observatory, a satellite managed by both NASA and the Japan Aerospace Exploration Agency, took a look at rainfall and cloud heights. Typhoon Soudelor's sustained winds were 105 knots (about 121 mph) when the GPM core observatory satellite flew above on August 5, 2015 at 1051 UTC. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a rainfall analysis was made from data collected from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. The analysis showed that Soudelor was very large and had a well-defined eye. Intense feeder bands are shown spiraling into the center. Three dimensional radar reflectivity data from GPM's DPR (ku Band) were used to construct a simulated cross section through Typhoon Soudelor's center. A view from the south showed the 3-D vertical structure of rainfall within Soudelor. On Aug. 5, the GPM satellite data was used to make a Some storms examined with GPM's radar reached 3-D vertical structure of rainfall within Soudelor.

Indigenous Knowledge and Endogenous Actions for Building Tribal Resilience After Typhoon Soudelor in Northern Taiwan
sustainability Article Indigenous Knowledge and Endogenous Actions for Building Tribal Resilience after Typhoon Soudelor in Northern Taiwan Su-Hsin Lee 1 and Yin-Jen Chen 2,* 1 Department of Geography, National Taiwan Normal University, 162, Section 1, Heping E. Rd., Taipei City 10610, Taiwan; [email protected] 2 Graduate Institute of Earth Science, Chinese Culture University, 55, Hwa-Kang Road, Yang-Ming-Shan, Taipei City 11114, Taiwan * Correspondence: [email protected] Abstract: Indigenous peoples often face signiﬁcant vulnerabilities to climate risks, yet the capacity of a social-ecological system (SES) to resilience is abstracted from indigenous and local knowledge. This research explored how the Tayal people in the Wulai tribes located in typhoon disaster areas along Nanshi River used indigenous knowledge as tribal resilience. It applied empirical analysis from secondary data on disaster relief and in-depth interviews, demonstrating how indigenous people’s endogenous actions helped during post-disaster reconstructing. With the intertwined concepts of indigenous knowledge, SESs, and tribes’ cooperation, the result presented the endogenous actions for tribal resilience. In addition, indigenous knowledge is instigated by the Qutux Niqan of mutual assistance and symbiosis among the Wulai tribes, and there is a need to build joint cooperation through local residence, indigenous people living outside of their tribes, and religious or social groups. The ﬁndings of tribal resilience after a typhoon disaster of co-production in the Wulai, Lahaw, and Fushan tribes include the importance of historical context, how indigenous people turn to their local knowledge rather than just only participating in disaster relief, and how they produce indigenous tourism for indigenous knowledge inheritance.

Guard and Mark A. Lander. In the earlier assessment, Soudelor was ranked as a high Category 3 tropical cyclone, with peak over-water wind speed of 110 kts with gusts to 130 kts (127 mph with gusts to 150 mph). As noted in the first press release, some of the damage on Saipan was consistent with even stronger gusts to at-or-above the Category 4 threshold of 115kt with gusts to 140 kt (130 mph with gusts to 160 mph). After considering the hundreds of damage pictures obtained on-site by the team and a careful analysis of the other factors relating to typhoon intensity, such as the measurements of the minimum central pressure and the characteristics of Soudelor’s eye on satellite imagery, the team has now raised it’s estimate of Soudelor equivalent over-water intensity to the 115 kt (130 mph) sustained wind threshold of a Category 4 tropical cyclone.
