Typhoon Neoguri Disaster Risk Reduction Situation Report1 DRR Sitrep 2014‐001 ‐ Updated July 8, 2014, 10:00 CET
Typhoon Neoguri Disaster Risk Reduction Situation Report1 DRR sitrep 2014‐001 ‐ updated July 8, 2014, 10:00 CET Summary Report Ongoing typhoon situation The storm had lost strength early Tuesday July 8, going from the equivalent of a Category 5 hurricane to a Category 3 on the Saffir‐Simpson Hurricane Wind Scale, which means devastating damage is expected to occur, with major damage to well‐built framed homes, snapped or uprooted trees and power outages. It is approaching Okinawa, Japan, and is moving northwest towards South Korea and the Philippines, bringing strong winds, flooding rainfall and inundating storm surge. Typhoon Neoguri is a once‐in‐a‐decade storm and Japanese authorities have extended their highest storm alert to Okinawa's main island. The Global Assessment Report (GAR) 2013 ranked Japan as first among countries in the world for both annual and maximum potential losses due to cyclones. It is calculated that Japan loses on average up to $45.9 Billion due to cyclonic winds every year and that it can lose a probable maximum loss of $547 Billion.2 What are the most devastating cyclones to hit Okinawa in recent memory? There have been 12 damaging cyclones to hit Okinawa since 1945. Sustaining winds of 81.6 knots (151 kph), Typhoon “Winnie” caused damages of $5.8 million in August 1997. Typhoon "Bart", which hit Okinawa in October 1999 caused damages of $5.7 million. It sustained winds of 126 knots (233 kph). The most damaging cyclone to hit Japan was Super Typhoon Nida (reaching a peak intensity of 260 kph), which struck Japan in 2004 killing 287 affecting 329,556 people injuring 1,483, and causing damages amounting to $15 Billion. -
Chapter 7. Building a Safe and Comfortable Society
Section 1 Realizing a Universal Society Building a Safe and Comfortable Chapter 7 Society Section 1 Realizing a Universal Society 1 Realizing Accessibility through a Universal Design Concept The “Act on Promotion of Smooth Transportation, etc. of Elderly Persons, Disabled Persons, etc.” embodies the universal design concept of “freedom and convenience for anywhere and anyone”, making it mandatory to comply with “Accessibility Standards” when newly establishing various facilities (passenger facilities, various vehicles, roads, off- street parking facilities, city parks, buildings, etc.), mandatory best effort for existing facilities as well as defining a development target for the end of FY2020 under the “Basic Policy on Accessibility” to promote accessibility. Also, in accordance with the local accessibility plan created by municipalities, focused and integrated promotion of accessibility is carried out in priority development district; to increase “caring for accessibility”, by deepening the national public’s understanding and seek cooperation for the promotion of accessibility, “accessibility workshops” are hosted in which you learn to assist as well as virtually experience being elderly, disabled, etc.; these efforts serve to accelerate II accessibility measures (sustained development in stages).

1 Storm Surge in Seto Inland Sea with Consideration Of
STORM SURGE IN SETO INLAND SEA WITH CONSIDERATION OF THE IMPACTS OF WAVE BREAKING ON SURFACE CURRENTS Han Soo Lee1, Takao Yamashita1, Tomoaki Komaguchi2, and Toyoaki Mishima3 Storm surge and storm wave simulations in Seto Inland Sea (SIS) in Japan were conducted for Typhoon Yancy (9313) and Chaba (0416) using an atmosphere (MM5)-wave (SWAN)-ocean (POM) modeling system. In the coupled modeling system, a new method for wave-current interaction in terms of momentum transfer due to whitecapping in deep water and depth-induced wave breaking in shallow water was considered. The calculated meteorological and wave fields show good agreement with the observations in SIS and its vicinities. The storm surge results also exhibit good accordance with the observations in SIS. To resolve a number of islands in SIS, we also performed numerical experiments with different grid resolutions and obtained improved results from higher resolutions in wave and ocean circulation fields. Keywords: Seto Inland Sea; storm surge; atmosphere-wave-ocean coupled model; air-sea interaction; whitecapping; depth-induced wave breaking INTRODUCTION Storm surge due to tropical cyclones (TCs) varies from place to place depending on the geographical features of the place we are interested in such as the effect of surrounding topography on meteorological fields, geographical shape of the bay or harbor, underwater bathymetry, tide, and interaction with other water bodies including rivers and open seas and oceans. In the storm surge modeling it is difficult to consider all of these effects such that we have to compromise some of them for simplifying a problem, more efficient modeling and engineering purpose. -
Tracking the Origin and Dispersion of Contaminated Sediments Transported by Rivers Draining the Fukushima Radioactive Contaminant Plume
Sediment Dynamics from the Summit to the Sea 237 (Proceedings of a symposium held in New Orleans, Louisiana, USA, 11–14 December 2014) (IAHS Publ. 367, 2014). Tracking the origin and dispersion of contaminated sediments transported by rivers draining the Fukushima radioactive contaminant plume HUGO LEPAGE1, OLIVIER EVRARD1, YUICHI ONDA2, CAROLINE CHARTIN1, IRENE LEFEVRE1, AYRAULT SOPHIE1 & PHILIPPE BONTE1 1 Laboratoire des Sciences du Climat et de l’Environnement (CEA, CNRS,UVSQ), F-91198 Gif-sur-Yvette France [email protected] 2 Center for Research in Isotopes and Environmental Dynamics (CRIED), Tsukuba University, Tsukuba, Japan Abstract This study was conducted in several catchments draining the main Fukushima Dai-ichi Power Plant contaminant plume in Fukushima prefecture, Japan. We collected soils and sediment drape deposits (n = 128) and investigated the variation in 137Cs enrichment during five sampling campaigns, conducted every six months, which typically occurred after intense erosive events such as typhoons and snowmelt. We show that upstream contaminated soils are eroded during summer typhoons (June–October) before being exported during the spring snowmelt (March–April). However, this seasonal cycle of sediment dispersion is further complicated by the occurrence of dam releases that may discharge large amounts of contaminants to the coastal plains during the coming years. Key words erosion; sediment; soil; Fukushima; radio-caesium; enrichment factor INTRODUCTION The Tohoku earthquake and the subsequent tsunami that occurred on 11 March 2011 impacted the Fukushima Dai-Ichi Nuclear Power Plant (FDNPP) and led to a significant atmospheric release of 137 radionuclides such as Cs (T1/2 = 30 years). About 80% of the release was transported out and over the Pacific Ocean, with the rest primarily deposited on the soils of Fukushima Prefecture as a result of wet atmospheric fallout. -
Sensitivity of Horizontal Resolution and Sea Spray to the Simulations
Sensitivity of horizontal resolution and sea spray to the simulations of Typhoon Roke in 2011 Akiyoshi Wada* *Meteorological Research Institute, Tsukuba, Ibaraki, 305-0052, JAPAN [email protected] 1. Introduction A previous report of Wada (2012) indicated that the horizontal resolution of 2 km was not enough to simulate the maximum intensity and structural change of Typhoon Roke in 2011 although the nonhydrostatic atmosphere model without ocean coupling well reproduced a rapid decrease in central pressure, 30 hPa in a day. In reality, a rapid intensification of Roke occurred when sea surface cooling was induced by the typhoon. This study addresses the sensitivity of horizontal resolution to the simulations of the typhoon. In addition, the sensitivity of an increase in turbulent heat fluxes due to the effect of sea spray induced by strong winds to the simulations was investigated in order to investigate the impact on the maximum intensity and intensification of simulated Roke. 2. Experimental design Summary of numerical simulations performed by Table 1 Summary of ocean coupling/noncoupling, horizontal resolution the atmosphere-wave-ocean coupled model (Wada et al., and sea spray parameterization Experiment Ocean Horizontal Sea spray 2010) is listed in Table1. The coupled model covered coupling resolution nearly a 1600 km x 1600 km computational domain with A2km NO 2 km - a horizontal grid spacing of 2 km in experiments A2km C2km YES 2 km - and C2km, and that of 1.5km in experiments C1.5km and CSP1.5km. The coupled model had 40 vertical levels C1.5km YES 1.5km - with variable intervals from 40 m for the near-surface CSP1.5km YES 1.5km Bao et al.(2000) layer to 1180 m for the uppermost layer. -

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. -

Introduction Osaka Bay on September 4, causing severe damage to Kansai area, Japan’s second largest economical region. We conducted field surveys around the Osaka Bay including the cities of Osaka, Annually, an average of 2.9 tropical cyclones Wakayama, Tokushima, Hyogo, and the island of Awaji-shima to (from 1951 to 2016) have hit Japan (Takagi and evaluate the situation of these areas immediately after Typhoon Esteban 2016; Takagi et al. 2017). The recent Jebi struck. Jebi generated high waves over large areas in these regions, and many coasts were substantially damaged by the Typhoon Jebi in September 2018 has been the combined impact of high waves and storm surges. The Jebi storm strongest tropical cyclone to come ashore in the last surge was the highest in the recorded history of Osaka. We used a 25 years since Typhoon Yancy (the 13th typhoon to storm surge–wave coupled model to investigate the impact caused by Jebi. The simulated surge level was validated with real data hit Japan, in 1993), severely damaging areas in its acquired from three tidal stations, while the wave simulation results trajectory. -
Development of and Studies with Coupled Ocean-Atmosphere Models
Section 9 Development of and studies with coupled ocean-atmosphere models Numerical simulations of the intensity change of Typhoon Choiwan (2009) and the oceanic response Akiyoshi Wada *Meteorological Research Institute, Tsukuba, Ibaraki, 305-0052, JAPAN [email protected] 1. Introduction Interactions between typhoons and the ocean are known to be important for predicting their intensity changes. In addition, a strong wind curl accompanied by typhoons induces sea surface cooling by passage of a TC, and causes variations in pCO2 in the upper ocean. The concentration of pCO2 is a function of the concentration of hydrogen ions, which is calculated by given water temperature, salinity, dissolved inorganic carbon (DIC) and total alkalinity (ALK). Wada et al. (2011a, b) reported that a simple chemical scheme coupled with an ocean general circulation model (Wada et al., 2011a) or coupled with a nonhydrostatic atmosphere model coupled with a multilayer ocean model and the third generation ocean wave model enabled us to simulate variations in pCO2 and air-sea CO2 flux caused by Typhoons Tina and Winnie (1997) and Typhoon Hai-Tang (2005). However, the variations in pCO2 could not be validated for numerical simulations of Typhoon Hai-Tang (2005) due to lack of observation. Bond et al. (2011) reported that pCO2, the water minus air value, increased dramatically giving a maximum value of 55 atm and then it slowly decreases at the surface mooring buoy named the Kuroshio Extension Observatory (KEO) buoy by passage of Typhoon Choiwan in 2009. In order to clarify the mechanism of the variations in pCO2 in the upper ocean by passage of Choiwan, numerical simulations were performed using a nonhydrostatic atmosphere model coupled with the multilayer ocean model and the third generation ocean wave model. -
