Typhoon Vongfong,known in the Philippines as Super Typhoon Ompong,was the most intense tropical cyclone worldwide in 2014,and struck Japan as a large tropical system. It also indirectly affected the Philippines and Taiwan. Vongfong was the nineteenth named storm and the ninth typhoon of the 2014 Pacific typhoon season. Estimates assess damage from Vongfong to have been over US$160 million,mainly for striking mainland Japan. At least 9 people were killed along the path of the typhoon in those countries.
Both the JMA and the JTWC upgraded Vongfong to a tropical storm on October 3. [1] [2] Under low vertical wind shear and excellent outflow,Vongfong intensified into a typhoon east of Guam on October 5. [3] [4] Afterwards,subsidence and moderate to strong vertical wind shear caused the typhoon to struggle to intensify. [5] On October 7,the PAGASA named the system Ompong,while it underwent rapid deepening owing to a TUTT cell. [6] The JTWC then classified Vongfong as the sixth super typhoon of 2014,shortly before reaching peak intensity with a round eye late on the same day. [7] [8]
Maintaining peak intensity for over one day,Vongfong began to gradually weaken on October 9,because of an eyewall replacement cycle. [9] On October 10,the structure of the typhoon decayed more,and it totally lost its eye feature on the next day when passing through Okinawa. [10] Due to mid-latitude westerlies,Vongfong's low-level circulation center became partially exposed. The typhoon accelerated east-northeastward on October 12 and made landfall over Kyushu. [11] [12] The system continued passing through the main islands of Japan and weakened into a severe tropical storm on October 13,before it became extratropical on October 14. [13] [14]
On September 30, a tropical disturbance began to persist near Ebon Atoll of the Marshall Islands, before the Japan Meteorological Agency (JMA) started to monitor the system as a low-pressure area early on the next day. [15] [16] Due to increased consolidation and favorable conditions, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert early on October 2, shortly before the Japan Meteorological Agency (JMA) upgraded the system to a tropical depression. [17] [18] More than a half of day later, the JTWC upgraded the system to a tropical depression and designated it as 19W, as a microwave imagery has already revealed the formative banding. [19] When the tropical depression was tracking along the southern periphery of a deep subtropical ridge, the JMA started to issue tropical cyclone advisories at 00:00 UTC on October 3, shortly before the JTWC upgraded 19W to a tropical storm because of further consolidation. [2] [20] In the afternoon, the JMA upgraded it to a tropical storm and named it Vongfong, when the fragmented banding was wrapping broadly into the slowly consolidating low-level circulation center with a weak eye-like feature. [1] [21]
Under low vertical wind shear and excellent outflow, the JTWC indicated that Vongfong had intensified into a typhoon at 06:00 UTC on October 4, as well as the JMA upgraded the system to a severe tropical storm at noon. [3] [22] With an improved northeastward channel into a tropical upper tropospheric trough (TUTT) cell, the storm briefly formed a pinhole eye on October 5, and the JMA upgraded it to a typhoon approximately 330 km (210 mi) east of Guam at 09:00 UTC. [4] [23] However, an area of subsidence north of the system and moderate to strong vertical wind shear began to impact Vongfong's development later. [5] The typhoon continued struggling to develop further early on October 6, as the broken convective banding was wrapping into a re-consolidating low-level circulation center. [24] In the second half of day, microwave imageries revealed that a thick eyewall structure had formed under a large central dense overcast, and a new but larger eye began to develop. Moreover, moderate vertical wind shear was being offset by excellent equatorward outflow and the motion of the system, when Vongfong was passing through the Northern Mariana Islands. [25]
Once Typhoon Vongfong entered the Philippine Area of Responsibility shortly after 06:00 UTC on October 7, the PAGASA named it Ompong. [6] The system started to undergo rapid deepening early on that day, owing to low vertical wind shear and multiple outflow mechanisms including a TUTT cell positioned to the east. The JTWC upgraded it to a super typhoon at noon, as the system had formed a 40 km (25 mi) round eye surrounded by a symmetric annulus of intense convection. [7] Vongfong reached peak intensity six hours later, when the system's T-number of the Dvorak technique had increased to 7.5 according to both of the JMA and the JTWC, becoming the first tropical cyclone to reach that status since Haiyan in 2013. As the result, the JMA indicated that the maximum ten-minute sustained winds had increased to 215 km/h (134 mph) and the system's atmospheric pressure had dropped to 900 hPa (27 inHg). [8] The JTWC also indicated that Vongfong had become equivalent to a Category 5 hurricane on the Saffir–Simpson hurricane wind scale, with maximum one-minute sustained winds at 285 km/h (177 mph). Additionally, although the typhoon was still generally tracking westward, it noticeably slowed down due to the weakening subtropical ridge. [26]
The system continued maintaining peak intensity and tracked west-northwestward on October 8, although the JTWC indicated that the eyewall had slightly warmed. [27] Having remained at peak intensity for 18 hours and at Category 5-equivalent intensity for 30 hours, Vongfong began to gradually weaken due to an eyewall replacement cycle. [28] The JMA reported that Vongfong had become a large typhoon in the afternoon. [29] Moreover, the system started to track northward along the western periphery of an extension of the subtropical ridge, as well as the poleward outflow channel was slightly diminished owing to the filled (weakened) TUTT cell which previously enhanced outflow. [9] Early on October 10, the JTWC downgraded Vongfong to a typhoon, as the eye became more ragged and surrounded by elongated convection. [30] The typhoon then turned north-northwestward in the afternoon due to some migratory ridging building in the north, when excellent outflow was being enhanced along the poleward side because of the mid-latitude westerlies. [31]
Vongfong totally lost the eye feature owing to increasing southwesterly vertical wind shear on October 11, yet its circulation grew even larger. [32] After crossing Okinawa Island and entering the East China Sea at 15:30 UTC, the overall structure of Typhoon Vongfong diminished more, resulting in the beginning of a significant weakening trend. [10] [33] On October 12, the convective organisation was almost diminished, as the only remaining deep convection became contained to the northern flank. Moreover, cold air stratocumulus clouds were observed streaming into the western periphery of the system, as the low level circulation center had become partially exposed and elongated caused by strong vertical wind shear. Because of these reasons, the JTWC downgraded Vongfong to a tropical storm early on that day. [11] The system accelerated east-northeastward along the northwestern periphery of the subtropical ridge in the afternoon and made landfall over Makurazaki, Kagoshima at 23:30 UTC, right before the JMA downgraded Vongfong to a severe tropical storm only a half of hour later. [12] [13] [34]
On October 13, Vongfong made landfall over Sukumo, Kōchi at 05:30 UTC, Awaji Island, Hyōgo at 10:30 UTC and Izumisano, Osaka at 11:00 UTC, yet the system had started the extratropical transition because of the formation of weak fronts. [35] [36] Isolated deep convection was displaced over the east quadrant of the exposed low-level circulation due to strong westerly vertical wind shear. [37] Vongfong became completely extratropical at 00:00 UTC on October 14, shortly after the system arrived at the area off the Pacific coast of the Tōhoku region. [14] Late on October 16, the extratropical system crossed the International Date Line. [38] The storm split into two systems south of the Alaska Peninsula during the afternoon of October 17; however, the low that constituted Vongfong's remnants was absorbed into the new storm only a few hours later, early on October 18. [39] [40]
Vongfong affected the Mariana Islands as an intensifying Category 2 typhoon on October 5. The highest winds gusts in Andersen Air Force Base were at 110 km/h (70 mph), while the highest wind gusts in Saipan were at 97 km/h (60 mph). Andersen Air Force Base also recorded rainfall of over 7 in (180 mm). In Yigo, 17 people were rescued from flooding. Total damage in Guam and Rota were estimated at $300,000. [41] [42]
Vongfong was also known as Ompong in the Philippines. The typhoon affected the country by affecting the Intertropical Convergence Zone, bringing flash floods in parts of Visayas and Mindanao. Luzon also experienced northeasterly winds from Ompong. PAGASA had warned rough sea conditions in the seaboards of most eastern parts of the archipelago as the typhoon reached its peak strength. [43] According to the NDRRMC, 4 people were killed due to heavy flooding as of October 18. Damages were estimated at PhP62.6 million (US$1.4 million). [44]
RV Ocean Researcher 5 (海研五號), a large research vessel belonging to the Taiwan Ocean Research Institute which was worth NT$1.46 billion (US$47.9 million) sank off the coast of Penghu at 20:11 TST (12:11 UTC) on October 10 as the vessel ran into a reef when it was sailing off in the afternoon on October 10, possibly due to the strong northeast surge in the Taiwan Strait enhanced by Typhoon Vongfong. Although 45 people on board were rescued, 2 researchers were killed, with 24 people injured. [45] One was pronounced dead upon arrival at hospital, and the other died after doctors tried everything to keep him alive but to no avail. [46]
Typhoon Vongfong, simply called “Typhoon No. 19” (台風第19号) in Japan, left some devastation throughout the country. On October 13, a 90-year-old man was found dead in an irrigation channel in Yazu, Tottori, as well as a 72-year-old man in Shikokuchūō, Ehime, who drowned after driving his light truck into a pond. [47] One man went missing after three people were swept into water at the port of Chichibu, Saitama on October 12; he was confirmed dead later. Moreover, Vongfong also injured at least 96 people in the 23 prefectures of Japan. 33 people in Okinawa were injured, including a 9-year-old girl in Naha and a male in his 20s in Itoman with their fingers sandwiched between doors. 14 people in Hyōgo were injured, including a 56-year-old female in Kobe getting fractured by strong winds when riding a bicycle. [48] Agriculture damages in Japan were calculated at ¥11.9 billion (US$111 million), [49] including ¥865 million (US$8.03 million) from Okinawa. [50]
The 2012 Pacific typhoon season was a slightly above average season that produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season, primarily due to Typhoon Bopha which killed 1,901 people in the Philippines. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2012, though most tropical cyclones typically develop between May and October. The season's first named storm, Pakhar, developed on March 28, while the season's last named storm, Wukong, dissipated on December 29. The season's first typhoon, Guchol, reached typhoon status on June 15, and became the first super typhoon of the year on June 17.
The 2014 Pacific typhoon season was a slightly below average season in terms of named storms, but featured the highest amount of Category 5 typhoons since 1997. This was mainly due to a developing El Niño that favors multiple powerful storms to form in the basin. The season formed twenty-three tropical storms, eleven typhoons, eight super typhoons, and seven Category 5 typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically develop between May and October. The season began with the development of Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi which dissipated on January 1 of the next year.
The 2015 Pacific typhoon season was a slightly above average season that produced twenty-seven tropical storms, eighteen typhoons, and nine super typhoons. The season ran throughout 2015, though most tropical cyclones typically develop between May and November. The season's first named storm, Mekkhala, developed on January 15, while the season's last named storm, Melor, dissipated on December 17. The season saw at least one named tropical system forming in each of every month, the first time since 1965. Similar to the previous season, this season saw a high number of super typhoons. Accumulated cyclone energy (ACE) during 2015 was extremely high, the third highest since 1970, and the 2015 ACE has been attributed in part to anthropogenic warming, and also the 2014-16 El Niño event, that led to similarly high ACE values in the East Pacific.
The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.
Typhoon Guchol, known in the Philippines as Super Typhoon Butchoy, was a powerful tropical cyclone which became the first typhoon to make landfall in Japan on June since 2004. The storm formed as tropical disturbance south-southeast of Pohnpei on June 7, and was upgraded to a tropical depression on June 10. The system later intensified in favorable conditions, and reached typhoon intensity on June 15. It reached peak intensity late on June 17, before making landfall over Japan as a typhoon on June 19. The system became extratropical shortly after traversing Japan and was last noted by the Japan Meteorological Agency on June 22.
This timeline documents all of the events of the 2014 Pacific typhoon season. Most of the tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
Typhoon Neoguri, known in the Philippines as Typhoon Florita, was a large and powerful tropical cyclone which struck Japan in 2014. The eighth named storm and the second typhoon of the annual typhoon season, Neoguri developed into a tropical storm on July 3 and then a typhoon on July 4. It rapidly deepened on July 5, reaching peak intensity late on July 6. Neoguri began to decay on July 7 and passed through Okinawa on July 8 and then making landfall over Kyushu as a severe tropical storm late on July 9. After Neoguri passed through the southern coast of Honshū on July 10, it became extratropical on July 11.
Typhoon Phanfone, known in the Philippines as Typhoon Neneng, was a powerful tropical cyclone which affected Japan in early October 2014. It was the eighteenth named storm and the eighth typhoon of the 2014 Pacific typhoon season. Phanfone started as a large area of convection well west of the International Date Line. The system was well organized and classified as Tropical Depression 18W on September 29. At the same day, it gained the name Phanfone due to very favorable conditions and intense thunderstorms rich with convection surrounding the storm's center. Phanfone would later go rapid intensification on October 1 due to warm sea-surface temperatures and very favorable environments. JTWC upgraded Phanfone to a Category 4 typhoon but weakened later back to Category 3 due to its eye replacing the old one and undergoing a minor eyewall replacement cycle.
Typhoon Nuri, known in the Philippines as Super Typhoon Paeng, was the third most intense tropical cyclone worldwide in 2014. Nuri developed into a tropical storm and received the name Paeng from the PAGASA on October 31, before it intensified into a typhoon on the next day. Under excellent conditions, especially the synoptic scale outflow, Nuri underwent rapid deepening and reached its peak intensity on November 2, forming a round eye in a symmetric Central dense overcast (CDO). Having maintained the impressive structure for over one day, the typhoon began to weaken on November 4, with a cloud-filled eye.
Typhoon Hagupit known in the Philippines as Super Typhoon Ruby, was the second most intense tropical cyclone in 2014. Hagupit particularly impacted the Philippines in early December while gradually weakening, killing 18 people and causing $114 million of damage in the country. Prior to making landfall, Hagupit was considered the worst threat to the Philippines in 2014, but it was significantly smaller than 2013's Typhoon Haiyan.
Typhoon Melor, known in the Philippines as Typhoon Nona, was a powerful tropical cyclone that struck the Philippines in December 2015. The twenty-seventh named storm and the eighteenth typhoon of the annual typhoon season, Melor killed 51 people and caused ₱7.04 billion in damage.
Typhoon Malakas, known in the Philippines as Typhoon Gener, was a powerful tropical cyclone which affected Taiwan and Japan in mid September 2016. It was the sixteenth named storm and the sixth typhoon of the annual typhoon season in 2016. Malakas formed on September 11, just south of Guam. The system gradually organized and improved its outer bands, which prompted JTWC to give its identifier as Tropical Depression 18W. A few hours later, JMA received its name Malakas for 18W. On September 13, Malakas entered the Philippine Area of Responsibility, which gained the name Gener by PAGASA. Despite its marginal conditions for further development, Malakas continued to intensify into a typhoon.
Typhoon Songda was the sixth most intense tropical cyclone of the Northwest Pacific Ocean in 2016. Also known as the Ides of October storm, it struck the Pacific Northwest region of the United States and Canada as a powerful extratropical cyclone. Songda was the twentieth named storm and the ninth typhoon of the annual typhoon season. The system developed into a tropical storm south of Minamitorishima on October 8 and strengthened into a typhoon on October 10. Songda reached its peak intensity southeast of Japan late on October 11 at an unusually high latitude, before it became extratropical on October 13.
Typhoon Nock-ten, known in the Philippines as Super Typhoon Nina, was the strongest Christmas Day tropical cyclone worldwide in terms of 1-minute sustained winds. Forming as a tropical depression southeast of Yap and strengthening into the twenty-sixth tropical storm of the annual typhoon season on December 21, 2016, Nock-ten intensified into the thirteenth typhoon of the season on December 23. Soon afterwards, the system underwent explosive intensification and became a Category 5-equivalent super typhoon early on December 25. Nock-ten weakened shortly afterwards before making eight landfalls over the Philippines. The typhoon weakened rapidly due to the landfalls as it entered the South China Sea on December 26, turned southwest, and ultimately dissipated on December 28 due to the winter monsoon.
Typhoon Lan, known in the Philippines as Super Typhoon Paolo, was the third-most intense tropical cyclone worldwide in 2017, behind only hurricanes Irma and Maria in the Atlantic. A very large storm, Lan was the twenty-first tropical storm and ninth typhoon of the annual typhoon season. It originated from a tropical disturbance that the United States Naval Research Laboratory had begun tracking near Chuuk on October 11. Slowly consolidating, it developed into a tropical storm on October 15, and intensified into a typhoon on October 17. It expanded in size and turned northward on October 18, although the typhoon struggled to intensify for two days. On October 20, Lan grew into a very large typhoon and rapidly intensified, due to favorable conditions, with a large well-defined eye, reaching peak intensity as a "super typhoon" with 1-minute sustained winds of 249 km/h (155 mph) – a high-end Category 4-equivalent storm – late on the same day. Afterward, encroaching dry air and shear caused the cyclone to begin weakening and turn extratropical, before it struck Japan on October 23 as a weaker typhoon. Later that day, it became fully extratropical before it was absorbed by a larger storm shortly afterward.
The 2021 Pacific typhoon season was the second consecutive to have below average tropical cyclone activity, with twenty-two named storms, and was the least active since 2011. Nine became typhoons, and five of those intensified into super typhoons. This low activity was caused by a strong La Niña that had persisted from the previous year. The season's first named storm, Dujuan, developed on February 16, while the last named storm, Rai, dissipated on December 21. The season's first typhoon, Surigae, reached typhoon status on April 16. It became the first super typhoon of the year on the next day, also becoming the strongest tropical cyclone in 2021. Surigae was also the most powerful tropical cyclone on record in the Northern Hemisphere for the month of April. Typhoons In-fa and Rai are responsible for more than half of the total damage this season, adding up to a combined total of $2.02 billion.
Typhoon Vongfong, known in the Philippines as Typhoon Ambo, was a strong tropical cyclone that impacted the Philippines in May 2020. Beginning as a tropical depression on May 10 east of Mindanao, Vongfong was the first storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow northward course, strengthening into a tropical storm on May 12 and curving west thereafter. The next day, Vongfong entered a period of rapid intensification, becoming a typhoon and attaining 10-minute maximum sustained winds of 150 km/h (93 mph). The storm made landfall at this intensity near San Policarpo, Eastern Samar, at 04:15 UTC on May 14. The system tracked across Visayas and Luzon, making a total of seven landfalls. Persistent land interaction weakened Vongfong, leading to its degeneration into a tropical depression over the Luzon Strait on May 17.
Typhoon Prapiroon, known in the Philippines as Severe Tropical Storm Florita, was a Category 1 typhoon that worsened the floods in Japan and also caused impacts in neighboring South Korea. The storm formed from an area of low pressure near the Philippines and strengthened to a typhoon before entering the Sea of Japan. The seventh named storm and the first typhoon of the annual annual typhoon season. Prapiroon originated from a low-pressure area far off the coast of Northern Luzon on June 28. Tracking westwards, it rapidly upgraded into a tropical storm, receiving the name Prapiroon due to favorable conditions in the Philippine Sea on the next day.
Severe Tropical Storm Maliksi, known in the Philippines as Severe Tropical Storm Domeng, was a tropical cyclone in June 2018 that brought rainfall to the Philippines and Japan. It caused 2 deaths and prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The fifth named storm and 4th tropical cyclone in the Philippine Area of Responsibility (PAR), it was first noted as an area of convection in the South of Palau on May 31.
Typhoon Chanthu, known in the Philippines as Super Typhoon Kiko, was the second most intense tropical cyclone worldwide in 2021 after Typhoon Surigae in April. It impacted the Cagayan Valley region of the Philippines and became the strongest typhoon to affect the Batanes province since Typhoon Meranti in 2016. The twenty-ninth tropical depression, fourteenth named storm and fourth typhoon of the 2021 Pacific typhoon season, Chanthu originated from a disturbance well east of the Philippine islands on September 5 which organized into a tropical depression later that day. By the next day, the depression had formed into a mature tropical storm which began to explosively intensify by September 7, featuring a pinhole eye on satellite, characteristic of rapidly intensifying storms. Chanthu became a Category 5-equivalent super typhoon by September 8, the highest category on the Saffir–Simpson scale. Subsequent eyewall replacement cycles caused intensity fluctuations, but on September 10, Chanthu peaked with 1-minute sustained winds of 285 km/h (180 mph) just northeast of extreme northeastern Luzon. The typhoon passed very near the Babuyan Islands before passing directly over Ivana, Batanes as a weakening but still powerful Category 5-equivalent super typhoon. Chanthu continued steadily weakening as it passed just east of Taiwan and eventually stalled just east of Shanghai, China. The storm eventually made its second and final landfall near Ikitsuki, Nagasaki in Japan, before crossing the country's mountainous terrain and becoming an extratropical cyclone on September 18. Chanthu then continued eastward and curved southward, before dissipating on September 20. According to Aon Benfield, economic losses totaled US$30 million.
