Genesis of Twin Tropical Cyclones As Revealed by a Global Mesoscale
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, D13114, doi:10.1029/2012JD017450, 2012 Genesis of twin tropical cyclones as revealed by a global mesoscale model: The role of mixed Rossby gravity waves Bo-Wen Shen,1,2 Wei-Kuo Tao,2 Yuh-Lang Lin,3 and Arlene Laing4 Received 12 January 2012; revised 26 April 2012; accepted 29 May 2012; published 12 July 2012. [1] In this study, it is proposed that twin tropical cyclones (TCs), Kesiny and 01A, in May 2002 formed in association with the scale interactions of three gyres that appeared as a convectively coupled mixed Rossby gravity (ccMRG) wave during an active phase of the Madden-Julian Oscillation (MJO). This is shown by analyzing observational data, including NCEP reanalysis data and METEOSAT 7 IR satellite imagery, and performing numerical simulations using a global mesoscale model. A 10-day control run is initialized at 0000 UTC 1 May 2002 with grid-scale condensation but no sub-grid cumulus parameterizations. The ccMRG wave was identified as encompassing two developing and one non-developing gyres, the first two of which intensified and evolved into the twin TCs. The control run is able to reproduce the evolution of the ccMRG wave and thus the formation of the twin TCs about two and five days in advance as well as their subsequent intensity evolution and movement within an 8–10 day period. Five additional 10-day sensitivity experiments with different model configurations are conducted to help understand the interaction of the three gyres, leading to the formation of the TCs. These experiments -

Dataset on the 6-Year Radiocesium Transport in Rivers Near Fukushima
www.nature.com/scientificdata oPEN Dataset on the 6-year radiocesium Data DescriptoR transport in rivers near Fukushima Daiichi nuclear power plant Keisuke Taniguchi 1,2 ✉ , Yuichi Onda 1, Hugh G. Smith 3, William Blake 4, Kazuya Yoshimura 5, Yosuke Yamashiki6 & Takayuki Kuramoto 2,7 Radiocesium released from the Fukushima Daiichi nuclear power plant (FDNPP) and deposited in the terrestrial environment has been transported to the sea through rivers. To study the long-term efect of riverine transport on the remediation process near the FDNPP, a monitoring project was initiated by the University of Tsukuba. It was commissioned by the Ministry of Education, Culture, Sports, Science, and Technology, and the Nuclear Regulatory Commission in June 2011, and was taken over by the Fukushima Prefectural Centre for Environmental Creation from April 2015. The activity concentration and monthly fux of radiocesium in a suspended form were measured in the project. This provides valuable measurement data to evaluate the impact of the accidentally released radiocesium on residents and the marine environment. It can also be used as verifcation data in the development and testing of numerical models to predict future impacts. Background & Summary A 9.0 magnitude earthquake on March 11, 2011, caused the Tokyo Electric Power Company’s Fukushima Daiichi nuclear power plant (FDNPP) to be damaged by a tsunami, causing a large accident that spread radioactive mate- rials into the environment1,2. Tis was the largest release of radioactivity into the environment since the Chernobyl nuclear power plant accident in 1986, and has been rated on the International Nuclear and Radiological Event Scale (INES) as a “Major Accident” by International Atomic Energy Agency (IAEA)3. -

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. -
PDF: Calling on the Japanese Government to Enhance Its
Calling on the Japanese government to enhance its NDC The Paris Agreement has entered the implementation phase this year, in 2020. Parties of the agreement are required to resubmit to the secretariat of the UNFCCC their Nationally Determined Contributions (NDCs), including greenhouse gas emissions reduction targets by 2030, before COP26 this November. The IPCC's Special Report “Global Warming of 1.5° C”, published in October 2018, indicated that average temperature rise should be kept below 1.5 ° C, rather than below 2.0 ° C, and in order to achieve that, carbon dioxide emissions need to be halved by 2030 and reach net zero by 2050. In fact, the year 2019 again saw a number of extreme weather events such as heat waves, wildfires, droughts and floods all over the world, which caused enormous damages. Japan was no exception. Unprecedented weather disasters including Typhoon Faxai and Typhoon Hagibis have brought huge loss to many people in Japan by destroying nature and their property. While the terms “climate crisis” and “climate emergency” are being widely used, young people around the world have risen up, urging adults to enhance their climate actions in the form of school strikes and peaceful marches. If Japan does not enhance its NDC in the midst of the escalating climate crisis year by year and the growing voices around the world calling for stronger climate actions, it not only ends up showing Japan's passive attitude on climate change to the world, but also jeopardizes the efforts of other countries that are seeking to enhance their emission reduction targets and measures even under difficult circumstances in each country. -

Our thoughts and support are with those suffering. 2 Since September 2019, the raging fires across the eastern and southeastern Australian coastal regions have burned over 17.9 million acres, destroyed over 2000 homes, and killed least 27 people. A billion animals have been caught in the fires, with some species now pushed to the brink of extinction. Skies are reddened from air heavy with smoke— smoke which can be seen 2,000km away in New Zealand and even from Chile, South America, which is more than 11,000km away. Currently, massive efforts are being taken to tackle the bushfires and protect people, animals, and homes in the vicinity.

Hurricane Andrew in Florida: Dynamics of a Disaster ^
Hurricane Andrew in Florida: Dynamics of a Disaster ^ H. E. Willoughby and P. G. Black Hurricane Research Division, AOML/NOAA, Miami, Florida ABSTRACT Four meteorological factors aggravated the devastation when Hurricane Andrew struck South Florida: completed replacement of the original eyewall by an outer, concentric eyewall while Andrew was still at sea; storm translation so fast that the eye crossed the populated coastline before the influence of land could weaken it appreciably; extreme wind speed, 82 m s_1 winds measured by aircraft flying at 2.5 km; and formation of an intense, but nontornadic, convective vortex in the eyewall at the time of landfall. Although Andrew weakened for 12 h during the eyewall replacement, it contained vigorous convection and was reintensifying rapidly as it passed onshore. The Gulf Stream just offshore was warm enough to support a sea level pressure 20-30 hPa lower than the 922 hPa attained, but Andrew hit land before it could reach this potential. The difficult-to-predict mesoscale and vortex-scale phenomena determined the course of events on that windy morning, not a long-term trend toward worse hurricanes. 1.

Challenges of Restoring and Rehabilitating Sewer Systems Damaged by the Great East Japan Earthquake and Tsunami
Journal of JSCE, Vol. 5, 279-297, 2017 Special Topic - Restoration and Recovery from the 2011 Great East Japan Earthquake( Invited Paper) CHALLENGES OF RESTORING AND REHABILITATING SEWER SYSTEMS DAMAGED BY THE GREAT EAST JAPAN EARTHQUAKE AND TSUNAMI Hiroyasu SATOH1 1Member of JSCE, Associate Professor, Graduate School of Frontier Sciences, The University of Tokyo (5-1-5 Kashiwanoha, Kashiwa, Chiba 277-8563, Japan) E-mail: [email protected] This is a review of the restoration and rehabilitation of sewer systems damaged by the Great East Japan Earthquake and Tsunami. The disaster caused serious damage to sewer systems, amounting to approxi- mately 470 billion JPY. The damage was mainly caused by the tsunami, but the damage due to liquefac- tion was also serious. The tectonic activity caused additional discharge loads to municipalities in coastal areas. The nuclear accident at Fukushima Daiichi Nuclear Power Plant also affected sewer systems in such forms as radio-contamination of sewage sludge and reduction of power supplies. In addition, migra- tion of users of sewer systems took place. In the restoration activities, sewage treatment plants (STPs) were restored step-by-step, and guidelines were developed to strengthen STPs against tsunamis. The ef- fectiveness of different countermeasures against earthquakes and liquefaction were examined, and new countermeasures were proposed. Software measures such as the introduction of business continuity plans and information technologies are recognized as effective measures for overcoming disasters. In particular, the sewer systems in Sendai City have been successfully restored and rehabilitated after the disaster, with different hardware and software measures. In contrast, sewer systems in small municipalities seriously damaged by the tsunami are still taking time to rehabilitate. -
