The 2005 Pacific typhoon season was the least active typhoon season since 2000, producing 23 named storms, of which 13 became typhoons. 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 2005, though most tropical cyclones typically develop between May and October. The season's first named storm, Kulap, developed on January 13, while the season's last named storm, Bolaven, dissipated on November 20. The season's first typhoon, Haitang, reached typhoon status on July 13, and became the first super typhoon of the year three days later.
The 2006 Pacific typhoon season was a near-average season which produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20.
The 1991 Pacific typhoon season was a slightly above-average season with 29 tropical storms, 17 typhoons and five super typhoons forming. It was quite a catastrophic season – Typhoon Yunya impacted the Philippines in mid June while in the same time experiencing a volcanic eruption, Typhoon Mireille severely impacting Japan, which became known for being the costliest typhoon on record with US$10 billion worths of damages, and Tropical Storm Thelma on November which became one of the deadliest storms to strike the Philippines, killing at least over 5,000 people.
Typhoon Nabi, known in the Philippines as Super Typhoon Jolina, was a powerful typhoon that struck southwestern Japan in September 2005. The 14th named storm of the 2005 Pacific typhoon season, Nabi formed on August 29 to the east of the Northern Mariana Islands. It moved westward and passed about 55 km (34 mi) north of Saipan on August 31 as an intensifying typhoon. On the next day, the Joint Typhoon Warning Center upgraded the storm to super typhoon status, with winds equivalent to that of a Category 5 hurricane on the Saffir–Simpson Hurricane Scale. The Japan Meteorological Agency estimated peak ten-minute winds of 175 km/h (109 mph) on September 2. Nabi weakened while curving to the north, striking the Japanese island of Kyushu on September 6. After brushing South Korea, the storm turned to the northeast, passing over Hokkaido before becoming extratropical on September 8, before dissipating on September 12.
Typhoon Tingting was a destructive tropical cyclone that produced record-breaking rains in Guam. The eighth named storm of the 2004 Pacific typhoon season, Tingting originated from a tropical depression over the open waters of the western Pacific Ocean. The storm gradually intensified as it traveled northwest, becoming a typhoon on June 28 and reaching its peak the following day while passing through the Mariana Islands. After maintaining typhoon intensity for three days, a combination of dry air and cooler sea surface temperatures caused the storm to weaken as it traveled northward. On July 1, the storm passed by the Bonin Islands, off the coast of Japan, before moving out to sea. By July 4, Tinting had transitioned into an extratropical cyclone. The remnants were last reported by the Japan Meteorological Agency, the Regional Specialized Meteorological Center for the western Pacific basin, near the International Date Line on July 13.
Typhoon Melor, known in the Philippines as Super Typhoon Quedan, was the second category 5 super typhoon in 2009. It interacted with Typhoon Parma in the first week of October southeast of Taiwan.
Typhoon Mirinae, known in the Philippines as Typhoon Santi, was the 34th depression and the 14th typhoon in the 2009 Pacific typhoon season. It came several weeks after Typhoons Ketsana and Parma devastated the Philippines, thus adding additional damage wrought by the two preceding typhoons.
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. 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 Chaba was the strongest tropical cyclone in the western Pacific during 2004 and caused a swath of damage from the Mariana Islands to Japan from August through September of that year. Chaba was the Japan's second costliest storm during the season, only behind Songda in September, and peaked as a typhoon with maximum sustained winds equivalent to that of a Category 5 on the Saffir–Simpson hurricane wind scale.
Severe Tropical Storm Linfa, known in the Philippines as Tropical Storm Chedeng, brought deadly flooding to areas of the Philippines and Japan in May and June 2003. The fourth named storm within the northwestern Pacific that year, Linfa developed as a tropical depression just off the western coast of Luzon on May 25. The disturbance quickly intensified to reach tropical storm intensity a few hours after cyclogenesis. However, intensification leveled off as Linfa executed a small clockwise loop before a subsequent landfall on Luzon on May 27. Due to land interaction the storm temporarily weakened and decoupled before reforming in the Philippine Sea. Afterwards Linfa began reintensifying and reached its peak intensity on May 29 with maximum sustained winds of 100 km/h (65 mph) and a barometric pressure of 980 mbar. Following its peak the tropical storm began to deteriorate and transitioned into an extratropical cyclone on May 30; these extratropical remnants continued to track northward through Japan before dissipating in the Sea of Okhotsk on June 4.
Tropical Storm Morakot, known in the Philippines as Tropical Storm Juaning, brought significant rainfall to Taiwan before alleviating drought conditions in mainland China in August 2003. The tenth named storm in the western Pacific that year, Morakot spawned from an area of disturbed weather in the Philippine Sea on July 31. Tracking northwest, favorable conditions allowed for the intensification of the system to tropical storm strength on August 2. Morakot reached peak intensity later that day with winds of 85 km/h (50 mph) and a minimum barometric pressure of 992 mbar. This intensity was held for several hours until less conducive atmospheric conditions slightly weakened the system; this was followed by Morakot making landfall on southern Taiwan on August 3. Subsequently, the storm weakened and moved into the Taiwan Strait before making its final landfall near Quanzhou, China the next day. The storm quickly weakened over the Chinese mainland, and dissipated entirely several hours after landfall.
Typhoon Saomai, known in the Philippines as Typhoon Osang, was a long-tracked and intense tropical cyclone that brought flooding rainfall in Japan and the Korean Peninsula in September 2000. The torrential precipitation in Japan was considered some of the worst in the past century.
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 Songda, known in the Philippines as Typhoon Nina, was the fifth-costliest typhoon on record. The 18th named storm of the 2004 Pacific typhoon season, Songda developed on August 26 near the Marshall Islands. Following a path that Typhoon Chaba took nine days prior, Songda moved west-northwestward and strengthened quickly amid favorable conditions.
Typhoon Soudelor, known in the Philippines as Super Typhoon Hanna, was the third most intense tropical cyclone worldwide in 2015 after Hurricane Patricia and Cyclone Pam as well as the strongest tropical cyclone of the 2015 Pacific typhoon season. Soudelor had severe impacts in the Northern Mariana Islands, Taiwan, and eastern China, resulting in 40 confirmed fatalities. Lesser effects were felt in Japan, South Korea and the Philippines. The thirteenth named storm of the annual typhoon season, Soudelor formed as a tropical depression near Pohnpei on July 29. The system strengthened slowly at first before entering a period of rapid intensification on August 2. Soudelor made landfall on Saipan later that day, causing extensive damage. Owing to favorable environmental conditions, the typhoon further deepened and reached its peak intensity with ten-minute maximum sustained winds of 215 km/h (134 mph) and a central atmospheric pressure of 900 hPa on August 3. The Joint Typhoon Warning Center assessed one-minute sustained winds at 285 km/h (177 mph), making Soudelor a Category 5-equivalent super typhoon. Steady weakening ensued thereafter as the storm moved generally west-northwest. Soudelor made landfall over Hualien, Taiwan, late on August 7 and emerged over in the Taiwan Strait early the next day. The typhoon soon moved inland over eastern China and degraded to a tropical depression by August 9.
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 Jebi, known in the Philippines as Super Typhoon Maymay, was the costliest typhoon in Japan's history in terms of insured losses. Jebi formed from a tropical disturbance south-southwest of Wake Island on August 26 and became the twenty-first named storm of the 2018 Pacific typhoon season on August 27. Amid favorable environmental conditions, Jebi quickly strengthened into a typhoon on August 29 as it headed west and rapidly intensified as it passed the Northern Mariana Islands on August 30. Jebi reached its peak intensity as a Category 5-equivalent typhoon on August 31, with 10-minute sustained winds of 195 km/h (120 mph), 1-minute sustained winds of 285 km/h (180 mph), and a minimum pressure of 915 hPa. Afterwards, Jebi began a slow weakening trend as it turned northwest, briefly passing through the Philippine Area of Responsibility on September 2. Jebi accelerated north-northeast towards Japan on September 3 as it interacted with the westerlies, and made landfalls over Shikoku and near Kobe early on September 4. Jebi quickly weakened over land and became an extratropical cyclone later that day over the Sea of Japan. Its remnants moved over the Russian Far East before dissipating on September 9.
Typhoon Yutu, known in the Philippines as Super Typhoon Rosita, was an extremely powerful tropical cyclone that caused catastrophic destruction on the islands of Tinian and Saipan in the Northern Mariana Islands, and later impacted the Philippines. It is the strongest typhoon ever recorded to impact the Mariana Islands, and is tied as the second-strongest tropical cyclone to strike the United States and its unincorporated territories by both wind speed and barometric pressure. It also tied Typhoon Kong-rey as the most powerful tropical cyclone worldwide in 2018. The fortieth tropical depression, twenty-sixth named storm, twelfth typhoon, and the seventh super typhoon of the 2018 Pacific typhoon season, Yutu originated from a low-pressure area that formed in the western Pacific Ocean on October 15. The disturbance organized into a tropical depression on the same day, as ocean sea-surface heat content increased. Shortly after becoming a tropical depression, the Joint Typhoon Warning Center (JTWC) assigned the system the identifier 31W. The system continued to strengthen, becoming a tropical storm several hours later, with the Japan Meteorological Agency (JMA) naming the system Yutu. Increasingly favorable conditions allowed Yutu to explosively intensify, as the system maintained deep convection and subsequently became a severe tropical storm and then a typhoon.
Typhoon Hagibis, known in Japan as Typhoon No.19 or Reiwa 1 East Japan Typhoon, was a large and costly tropical cyclone that caused widespread destruction in Japan. The thirty-eighth depression, nineteenth tropical storm, ninth typhoon, and third super typhoon of the 2019 Pacific typhoon season, it was the strongest typhoon to strike mainland Japan in decades, and one of the largest typhoons ever recorded, with a peak gale-force diameter of 825 nautical miles. The typhoon raised global media attention, as it greatly affected the 2019 Rugby World Cup being hosted by Japan. Hagibis was also the deadliest typhoon to strike Japan since Typhoon Fran in 1976.
