Typhoon Bavi,known in the Philippines as Severe Tropical Storm Igme,was a powerful tropical cyclone that made landfall in North Korea in August 2020. The eighth named storm and third typhoon of the 2020 Pacific typhoon season,Bavi formed from a low pressure area depression on August 21 to the north of the Philippines and strengthened into a tropical storm on August 22. Bavi gradually strengthened as it skirted Taiwan and Okinawa,and became a typhoon on August 24. Passing over warm waters,Bavi turned to northwest and reached its peak intensity near Jeju Island on August 26. Thereafter,increasing wind shear and cooler waters caused Bavi to quickly weaken. Bavi made landfall in North Korea on August 27,and became an extratropical cyclone shortly thereafter.
Bavi caused minimal damage in portions of South Korea and Japan,but caused widespread structural damage and flooding in North Korea. It was the first storm in two weeks span to affect Korea. Others were Maysak and Haishen.
On August 19, the JTWC began monitoring a broad area of low pressure situated a couple hundred miles northeast of the Philippine archipelago. By the next day, the system rapidly organised, and the JTWC subsequently issued a Tropical Cyclone Formation Alert (TCFA), and on August 21, the area of low pressure organized into Tropical Depression 09W. [1] At 15:00 UTC, the PAGASA named the system "Igme" and issued a severe weather bulletin for it. [2] By the next day the system had intensified into a tropical storm, and the JMA gave it the name Bavi and upgraded it, with the JTWC doing the same. [3] Favorable conditions allowed Bavi to rapidly intensify, and by 12:00 UTC on August 22, the system became a severe tropical storm. The system left the Philippine Area of Responsibility on the same day. [4] Bavi's period of rapid intensification was brief, with its intensification significantly slowed on August 23.
On August 24, Bavi was upgraded into a typhoon by the JTWC as it continued to slowly intensify. Later on that day, it became a Category 2 typhoon, with it becoming a Category 3 typhoon on the next day. As Bavi moved closer to the Korean peninsula, one person died in Jeju Island on August 25. [5] Soon afterwards, as Bavi moved northwards into very hostile conditions and high wind shear, which caused Bavi to rapidly weaken. Wind shear was still high and the storm started extratropical transition. Around 00:30 UTC on August 27, a weakened Bavi made landfall over North Pyongan Province, North Korea as a minimal typhoon. [6] Both the JMA and the JTWC issued their final advisory on Bavi a few hours later as it became an extratropical cyclone over Northeastern China.
Bavi caused wind gusts of over 60 mph (97 km/h) and dropped 300 mm (12 in) of rain on the island of Okinawa. [7] Agricultural damage in Okinawa Prefecture was JP¥25.14 million (US$237 thousand). [8] Large waves associated with Bavi were reported as far away as Kagoshima Prefecture. [9]
In South Korea, as a precaution over 470 flights were cancelled and railroad services were halted. Public parks were also closed for the typhoon. [10]
In Jeju Island, five people were swept away by strong waves, one of them died later. [11] Heavy rainfall was also reported in the island with a maximum amount of 399.5 mm (15.73 in) being reported near Mount Halla. [12] Despite a close pass to mainland South Korea, damage was minimal, consisting mostly of power outages, broken windows, and downed trees. Nevertheless, more than 100 reports of damage was submitted. The typhoon forced about 30 people in Gokseong, South Jeolla Province, to evacuate due to landslides. About 440 flights were cancelled at eleven airports across the country, while nearly 160 passenger ferries were grounded on 99 ferry routes. [13] Roughly 1,600 households in South Korea lost power. [14] Losses in Jeju reached ₩484 million (US$408 thousand). [15]
North Korean leader Kim Jong-un held a high-level political conference where he voiced his concerns about Typhoon Bavi and the COVID-19 pandemic. [16] He ordered all levels of the Workers' Party to take steps to protect the country from the threat of the storm. [17]
Snapped utility poles and trees were reported near Bavi's landfall location, as well as flooded roads. A peak precipitation amount of 224 mm (8.8 in) was reported in Anju. [7] Several homes and public buildings were damaged in North and South Hwanghae provinces. [18]
In an unusual step, Korean Central Television remained on the air overnight on 27 August as the typhoon impacted the country, interrupting programs every 30 minutes with updates from the State Hydro-Meteorological Administration. It later broadcast images of storm damage, as well as field reports from correspondents in Pyongyang and Nampo—a major divergence from the strict format and content of all other KCTV news bulletins, where the activities of Kim Jong-un take precedence. No other coverage of the storm was included in KCTV bulletins until 28 August, when a story followed Kim as he inspected damage from the storm. [17] [19]
Several weather alerts were issued for portions of China as Typhoon Bavi neared. The Chinese Ministry of Emergency Management stated that 20,000 firefighters had been deployed equipped with 329 rescue boats.
In Northeast China, rounds of heavy downpours brought up to 150 mm (5.9 in) of rainfall in some areas. [20] Damage in Dalian amounted to be CN¥76.54 million (US$11.1 million). [21]
The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It had an ACE over 400 units, making it one of the most active seasons worldwide. 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 2002, though most tropical cyclones typically develop between May and October. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later.
The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. It also featured the lowest number of typhoons on record, with only five reaching this intensity. This was mainly due to a strong La Niña which persisted from last year. The season was also below-average in named storms, with only 20 of such spawning. It had no official bounds; it ran year-round in 1999, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The first named storm, Hilda, developed on January 6, while the last named storm, Gloria, dissipated on November 16.
The 1995 Pacific typhoon season was a slightly below average season in terms of named storms, ending a 6-year stretch of above average activity. It occurred all year round, though most tropical cyclones formed between May and November.
Typhoon Ewiniar, known in the Philippines as Typhoon Ester, was the third named storm of the 2006 Pacific typhoon season and one that lasted for twelve days as a tropical cyclone, moving on a generally northward track. During its lifespan, it affected Palau, Yap, eastern China, the Ryūkyū Islands of Japan, South Korea as well as North Korea, briefly threatening to make landfall in North Korea before doing so in South Korea. Ewiniar is responsible for at least 181 deaths. However, an unofficial report stated that up to 10,000 people had been killed by flooding in North Korea, with 4,000 people missing.
The 2008 Pacific typhoon season was a below average season which featured 22 named storms, eleven typhoons, and two super typhoons. The season had no official bounds; it ran year-round in 2008, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation during the 2008 Pacific typhoon season. The 2008 Pacific typhoon season officially started on January 1, 2008 and ended on January 1, 2009.
The 2010 Pacific typhoon season, with 14 named storms, was the least active Pacific typhoon season on record. Seven of them strengthened into typhoons while one reached super typhoon intensity. All of the 14 named storms developed west of 150°E.
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.
The 2019 Pacific typhoon season was the costliest Pacific typhoon season on record, just ahead of the previous year and 2023. The season featured fairly above-average tropical cyclone activity for the second consecutive year, producing 29 named storms, 17 typhoons, and five super typhoons, also, it was the final season of the Western Pacific's consecutive active hurricane seasons that started in 2013. The season's first named storm, Pabuk, reached tropical storm status on January 1, becoming the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record that was held by Typhoon Alice in 1979. The season's first typhoon, Wutip, reached typhoon status on February 20. Wutip further intensified into a super typhoon on February 23, becoming the strongest February typhoon on record, and the strongest tropical cyclone recorded in February in the Northern Hemisphere. The season's last named storm, Phanfone, dissipated on December 29 after it made landfall in the Philippines.
Typhoon Sanba, known in the Philippines as Super Typhoon Karen, was the strongest tropical cyclone worldwide in 2012. The sixteenth named storm and tenth typhoon of the annual typhoon season, Sanba formed as a tropical depression east of the Philippines on September 10. The storm gradually intensified as it moved generally northward in an area favorable for tropical development. The system was soon upgraded to a tropical storm less than a day after formation and subsequently further to a typhoon on September 12. Later that day, Sanba entered a phase of rapid intensification, and quickly strengthened. On September 13, the system attained its peak intensity with maximum sustained winds of 125 mph (205 km/h), and a barometric pressure of 900 mbar, becoming the strongest typhoon in the Western Pacific Ocean since Megi in 2010. Accelerating towards more northerly latitudes, a period of gradual weakening ensued afterwards as its eye expanded. It made landfall on South Korea late on September 17 as a typhoon before transitioning into an extratropical cyclone the following day. Sanba's remnants tracked into the Primorsky Krai region of eastern Russia before they were last noted on September 19.
The 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. Despite that, this season featured Super Typhoon Goni, which made the strongest landfall worldwide in terms of 1-minute wind speed. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.
Typhoon Olga, also known in the Philippines as Typhoon Ising, was a destructive and deadly typhoon that hit Korean Peninsula in 1999. Olga killed 106 people in Korea and caused $657 million in damages.
This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed 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. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.
Typhoon Chaba, known in the Philippines as Super Typhoon Igme, was the fourth most intense tropical cyclone in 2016 and the strongest tropical cyclone to make landfall in South Korea since Sanba in 2012. Chaba also caused 7 deaths in the country. Typhoon Chaba was the eighteenth named storm and the eighth typhoon of the 2016 Pacific typhoon season. Chaba originated as a depression around the east-northeast of Guam. Being in a marginally favorable environment, JMA proceeds to name the system as Chaba. On September 28, JTWC gave its identifier as Tropical Depression 21W. Its LLCC starts to improve, prompting the JTWC to upgrade into a tropical storm. Chaba entered the Philippine Area of Responsibility, receiving the name Igme as it moved northwestwards. Chaba became more symmetrical which later ensued its rapid intensification.
The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
Typhoon Maysak, known in the Philippines as Typhoon Julian, was a deadly, damaging and powerful tropical cyclone that struck the Ryukyu Islands and the Korean Peninsula in September 2020. The third typhoon of the 2020 Pacific typhoon season, Maysak formed from a tropical disturbance. The disturbance gradually organized, receiving the name Julian from PAGASA as it became a tropical depression. As the depression strengthened, the JMA subsequently named the system Maysak. Maysak rapidly intensified into a strong typhoon before weakening and making landfall in South Korea.
Typhoon Haishen, known in the Philippines as Super Typhoon Kristine, was a powerful tropical cyclone that became the first super typhoon of the 2020 Pacific typhoon season. Being also the tenth named storm and this season's fifth typhoon, Haishen's origins can be tracked back to a disorganised low pressure area situated near Guam. While the disturbance tracked south-westward and quickly organised, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system, and a day later, on September 1, the system became a tropical depression. The depression strengthened into Tropical Storm Haishen according to the Japan Meteorological Agency as it moved southwestward. At about 12:00 UTC on September 2, the Philippine Atmospheric, Geological and Astronomical Services Administration indicated that Haishen had entered the Philippine Area of Responsibility and was subsequently named Kristine. Later that day, Haishen became a typhoon. Intensification on September 3 was significant. Drifting northwestward into extremely favorable conditions, Haishen became a category 3-equivalent typhoon, acquiring a pinhole eye, before undergoing an eyewall replacement cycle (EWRC). Strengthening resumed soon after and the JTWC assessed wind speeds of 135 kn as it peaked as a powerful Category 4 super typhoon and had attained a new, symmetrical, clear eye.
Typhoon Lingling, also known in the Philippines as Typhoon Liwayway, was a powerful typhoon that hit the Philippines, China, and Korea in 2019. It was also the strongest to strike North Korea. Lingling caused agriculture damage to Japan and the Korean Peninsula, causing several million USD in damage. Overall, Lingling caused $300 million in damage and claimed 8 lives.
The Korean Peninsula is a peninsula region located over Eastern Asia. The region is divided into North Korea and South Korea.
