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. -
2014 North Atlantic Hurricane Season Review
2014 North Atlantic Hurricane Season Review WHITEPAPER Executive Summary The 2014 Atlantic hurricane season was a quiet season, closing with eight 2014 marks the named storms, six hurricanes, and two major hurricanes (Category 3 or longest period on stronger). record – nine Forecast groups predicted that the formation of El Niño and below consecutive years average sea surface temperatures (SSTs) in the Atlantic Main – that no major Development Region (MDR)1 through the season would inhibit hurricanes made development in 2014, leading to a below average season. While 2014 landfall over the was indeed quiet, these predictions didn’t materialize. U.S. The scientific community has attributed the low activity in 2014 to a number of oceanic and atmospheric conditions, predominantly anomalously low Atlantic mid-level moisture, anomalously high tropical Atlantic subsidence (sinking air) in the Main Development Region (MDR), and strong wind shear across the Caribbean. Tropical cyclone activity in the North Atlantic basin was also influenced by below average activity in the 2014 West African monsoon season, which suppressed the development of African easterly winds. The year 2014 marks the longest period on record – nine consecutive years since Hurricane Wilma in 2005 – that no major hurricanes made landfall over the U.S., and also the ninth consecutive year that no hurricane made landfall over the coastline of Florida. The U.S. experienced only one landfalling hurricane in 2014, Hurricane Arthur. Arthur made landfall over the Outer Banks of North Carolina as a Category 2 hurricane on July 4, causing minor damage. While Mexico and Central America were impacted by two landfalling storms and the Caribbean by three, Bermuda suffered the most substantial damage due to landfalling storms in 2014.Hurricane Fay and Major Hurricane Gonzalo made landfall on the island within a week of each other, on October 12 and October 18, respectively. -

An Incoherent Subseasonal Pattern of Tropical Convective and Zonal Wind
An incoherent subseasonal pattern of tropical convective and zonal wind anomalies contributed to weak signals on both the Wheeler-Hendon (RMM) and CPC MJO indices during the past week. The spatial pattern of upper-level velocity potential anomalies exhibited influences from higher frequency modes, such as tropical cyclone activity over the eastern Pacific and anomalous divergence over Africa. During the past several days, however, these conflicting signals have weakened. Additionally, constructive interference of a strong equatorial Rossby Wave (ERW) and a Kelvin Wave over the eastern Indian Ocean and Maritime Continent contributed to an ongoing large area of enhanced convection. The RMM Index has responded to this evolution and is currently projecting a signal in Phase-4. Dynamical model MJO index forecasts are consistent with a rapid propagation of this signal eastward over the Maritime Continent during the upcoming week, likely due to influence from the Kelvin Wave. Beyond this period, however, the GFS weakens the MJO signal while the CFS, UKMET, and ECMWF models continue a slower eastward propagation over the western Pacific. There is uncertainty whether the enhanced convection over the Maritime Continent associated with the interactions between a more transient Kelvin Wave and the ERW will evolve into a more robust subseasonal signal on the MJO time scale. Due to the consensus among numerous dynamical models, however, impacts of MJO propagation from the Maritime Continent to the West Pacific were considered for this outlook. Tropical cyclones developed over both the eastern and western Pacific basins during the past week. Super Typhoon Neoguri, the third typhoon of 2014 and the first major cyclone, developed east of the Philippines on 3 July. -
