A Summary of Palau's Typhoon History 1945-2013
A Summary of Palau’s Typhoon History 1945-2013 Coral Reef Research Foundation, Palau Dec, 2014 © Coral Reef Research Foundation 2014 Suggested citation: Coral Reef Research Foundation, 2014. A Summary of Palau’s Typhoon History. Technical Report, 17pp. www.coralreefpalau.org Additions and suggestions welcome. Please email: [email protected] 2 Summary: Since 1945 Palau has had 68 recorded typhoons, tropical storms or tropical depressions come within 200 nmi of its islands or reefs. At their nearest point to Palau, 20 of these were typhoon strength with winds ≥64kts, or an average of 1 typhoon every 3 years. November and December had the highest number of significant storms; July had none over 40 kts and August had no recorded storms. Data Compilation: Storms within 200 nmi (nautical miles) of Palau were identified from the Digital Typhoon, National Institute of Informatics, Japan web site (http://agora.ex.nii.ac.jp/digital- typhoon/reference/besttrack.html.en). The storm tracks and intensities were then obtained from the Joint Typhoon Warning Center (JTWC) (https://metoc.ndbc.noaa.gov/en/JTWC/). Three storm categories were used following the JTWC: Tropical Depression, winds ≤ 33 kts; Tropical Storm, winds 34-63 kts; Typhoon ≥64kts. All track data was from the JTWC archives. Tracks were plotted on Google Earth and the nearest distance to land or reef, and bearing from Palau, were measured; maximum sustained wind speed in knots (nautical miles/hr) at that point was recorded. Typhoon names were taken from the Digital Typhoon site, but typhoon numbers for the same typhoon were from the JTWC archives. -
Detail Response to Referee #1 (Anonymous) in the Following Letter, Each Comment by Referee #1 in Black Is Followed by Our Replies in Red
Detail response to Referee #1 (anonymous) In the following letter, each comment by Referee #1 in black is followed by our replies in red. This paper proposes an assessment of the risk of coastal flooding and submersion by waves in one of the Palau islands surrounded by a coral reef in 2100, in a context of climate change. The study is certainly of interest, the study is rather comprehensive, well conducted and the paper is concise, clear and well written. The objectives of the paper are clearly exposed and the conclusions correspond to these objectives. We are grateful to you that you review. I have however two main concerns, that in my opinion prevent the acceptance of the paper in its present state: 1- The authors state that their first objective is to assess the present-day efficiency of the Palau coral reef as wave breaker and natural barrier against water level rise during a tropical cyclone (TC). They give (from what I understand) the corresponding figures obtained from a numerical hydrodynamic modeling, using as forgings the outer wave significant height (SWHo), the outer significant wave period, and the outer water level. These forcings are taken from a GFS simulation and observations of SWH in similar conditions. The percent of reduction of wave height due to the reef is 85.7% (87.9%) with (without) storm surge. As these values are used as a reference in the projective part of the paper, it would be relevant to confirm them (at least at first order) using observations. Recent TCs (Bopha and Haiyan) hit Palau, and it is may be possible to find even crude observations of (outer) SWHo and (reef) SWHr to check either the value of SWHr or the percentage of reduction (Table1). -
Appendix 8: Damages Caused by Natural Disasters
Building Disaster and Climate Resilient Cities in ASEAN Draft Finnal Report APPENDIX 8: DAMAGES CAUSED BY NATURAL DISASTERS A8.1 Flood & Typhoon Table A8.1.1 Record of Flood & Typhoon (Cambodia) Place Date Damage Cambodia Flood Aug 1999 The flash floods, triggered by torrential rains during the first week of August, caused significant damage in the provinces of Sihanoukville, Koh Kong and Kam Pot. As of 10 August, four people were killed, some 8,000 people were left homeless, and 200 meters of railroads were washed away. More than 12,000 hectares of rice paddies were flooded in Kam Pot province alone. Floods Nov 1999 Continued torrential rains during October and early November caused flash floods and affected five southern provinces: Takeo, Kandal, Kampong Speu, Phnom Penh Municipality and Pursat. The report indicates that the floods affected 21,334 families and around 9,900 ha of rice field. IFRC's situation report dated 9 November stated that 3,561 houses are damaged/destroyed. So far, there has been no report of casualties. Flood Aug 2000 The second floods has caused serious damages on provinces in the North, the East and the South, especially in Takeo Province. Three provinces along Mekong River (Stung Treng, Kratie and Kompong Cham) and Municipality of Phnom Penh have declared the state of emergency. 121,000 families have been affected, more than 170 people were killed, and some $10 million in rice crops has been destroyed. Immediate needs include food, shelter, and the repair or replacement of homes, household items, and sanitation facilities as water levels in the Delta continue to fall. -
Briefing Note on Typhoon Goni
Briefing note 12 November 2020 PHILIPPINES KEY FIGURES Typhoon Goni CRISIS IMPACT OVERVIEW 1,5 million PEOPLE AFFECTED BY •On the morning of 1 November 2020, Typhoon Goni (known locally as Rolly) made landfall in Bicol Region and hit the town of Tiwi in Albay province, causing TYPHOON GONI rivers to overflow and flood much of the region. The typhoon – considered the world’s strongest typhoon so far this year – had maximum sustained winds of 225 km/h and gustiness of up to 280 km/h, moving at 25 km/h (ACT Alliance 02/11/2020). • At least 11 towns are reported to be cut off in Bato, Catanduanes province, as roads linking the province’s towns remain impassable. At least 137,000 houses were destroyed or damaged – including more than 300 houses buried under rock in Guinobatan, Albay province, because of a landslide following 128,000 heavy rains caused by the typhoon (OCHA 09/11/2020; ECHO 10/11/2020; OCHA 04/11/2020; South China Morning Post 04/11/2020). Many families will remain REMAIN DISPLACED BY in long-term displacement (UN News 06/11/2020; Map Action 08/11/2020).

We focus on observed TC changes in the western North Pacific (WNP) basin, including frequency, intensity, precipitation, track pattern, and storm surge. Results from an updated survey of impacts of past TC activity on various Members of the Typhoon Committee are also reported. Existing TC datasets continue to show substantial interdecadal variations in basin-wide TC frequency and intensity in the WNP. There has been encouraging progress in improving the consensus between different datasets concerning intensity trends. A statistically significant northwest- ward shift in WNP TC tracks since the 1980s has been documented. There is low-to-medium confidence in a detectable poleward shift since the 1940s in the average latitude where TCs reach their peak intensity in the WNP. A worsening of storm inundation levels is believed to be occurring due to sea level rise-due in part to anthropogenic influence-assuming all other factors equal. -
