The 2000 Pacific typhoon season marked the first year using names contributed by the World Meteorological Organization. It was a rather below-average season, producing a total of 23 tropical storms, 13 typhoons and 4 intense typhoons. The season ran throughout 2000, though typically most tropical cyclones develop between May and October. The season's first named storm, Damrey, developed on May 7, while the season's last named storm, Soulik, dissipated on January 4 of the next year. The Accumulated Cyclone Energy (ACE) index for the 2000 Pacific typhoon season as calculated by Colorado State University using data from the Joint Typhoon Warning Center was 252.9units.[1]
The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and the 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones, which often results in a storm having two names. The Japan Meteorological Agency(JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65km/h (40mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration(PAGASA) assigns names to tropical cyclones which move into or form as tropical depressions in their area of responsibility, located between 115°E and 135°E and between 5°N and 25°N, regardless of whether or not the tropical cyclone has already been given a name by the JMA. Tropical depressions monitored by the United States' Joint Typhoon Warning Center(JTWC) are given a number with a "W" suffix.
The season began with Typhoon Damrey on May 4, marking the first tropical depression, tropical storm, typhoon, and super typhoon of the season. The storm later dissipated after eight days. Five days later, Tropical Storm Longwang formed, drifting across the Philippines, dissipating after three days. Three tropical depressions formed across the rest of May and the first part of July. Typhoon Kirogi later formed on July 2, affecting eastern Japan, then dissipating after six days. The next day, Typhoon Kai-tak later formed, affecting Taiwan, then dissipating after seven days.
Three tropical depressions, two tropical storms (Tembin, Chanchu), and one severe Tropical Storm (Bolaven) formed on the rest of July, then Typhoon Jelawat formed in August as a strong typhoon. Two tropical depressions formed, then Typhoon Ewiniar formed and disspated. Three tropical depressions formed, then Typhoon Bilis formed as a super typhoon, then a tropical depression formed. A tropical depression, a tropical storm (Bopha), and a typhoon (Wukong) formed on the first week of September, then on the second week, a tropical depression and a severe tropical storm (Sonami) formed. Then on the third week Typhoon Shanshan formed, and for the fourth week, two tropical depressions formed.
In October, three tropical depressions formed, then Typhoon Yagi formed. Typhoon Xangsane also formed, then dissipated at the end of October. In November, a severe tropical storm (Bebinca) and a tropical depression formed. In December, Tropical Storm Rumbia formed, then three tropical depressions, then Typhoon Soulk.
The first storm of the season started out as a tropical low near Palau on May 3, when the JTWC first gave the system a poor chance of formation. However within the next few hours the low quickly organized, and the next day the JMA recognized the low as a depression. Operationally it wasn't until May 5 that the JTWC issued its first warning for the newly formed depression. Drifting northwest the depression gradually organized into a tropical storm on May 6. It was given the name Asiang on May 6 by PAGASA[4] and Damrey on May 7 by the JMA, respectively. At this time a weakening sub-tropical ridge was moving northward causing Damrey to move in a northeasterly direction. Damrey became a typhoon early on May 8 and soon thereafter satellite images began to show an eye forming at the center. During the next 24 hours Damrey quite steadily intensified, reaching winds of 130mph (215km/h) by May 9. The system became very symmetrical and small, allowing the typhoon to reach a peak intensity of 180mph (290km/h) and gusts as high as 220mph late on May 9. The JTWC unofficially estimated a pressure of 878 mbar, which would make it one of the strongest tropical cyclones ever. Due to the compact structure of the typhoon it would only take twenty-four hours of high vertical wind shear, from a nearby high pressure, to reduce Damrey to a tropical storm. The convection continue to decrease around the LLCC and the system picked up in forward momentum under deteriorating environment.[5] By May 12 Damrey became fully extra-tropical and eventually dissipated on May 16.[6]
Damrey was the strongest May typhoon since Phyllis in 1958. Phyllis, however, attained higher sustained winds of 185mph (295km/h).[7] Damrey had no significant effects on land in its life.
On May 15, a monsoonal trough associated with a low pressure area formed north west of the Philippines. On May 17 the low pressure area started to drift across the northern Philippines, and rapidly intensified into a tropical storm before quickly dissipating due to vertical wind shear on May 20. The remnants were soon absorbed by a non-tropical low on May 22.
On May 20, a low pressure area formed south of Hong Kong and drifted east towards the Philippines. On May 21 the low pressure area rapidly organized and strengthened into a tropical depression. However it quickly dissipated due to vertical wind shear.
A vortex in an active trough over the South China Sea developed into a small tropical depression on June 18, 35km south-southwest of Hong Kong. It moved northward and made landfall that day, with its very small circulation being well captured by the Observatory's network of automatic weather stations. The depression brought light rain to Hong Kong and strong winds. Although this tropical depression was widely recognised by Asian agencies, there are still disputes on the nature of this system. It had an unusually small size and formed surprisingly close to land.[8]
On June30, an area of disturbed weather was identified roughly 650km (405mi) east of the Philippine island of Mindanao. This system gradually organized as it remained stationary, prompting the JTWC to issue a TCFA the following day. The JMA and JTWC began monitoring the disturbance as a tropical depression early on July2, with the former classifying it as 05W. Several hours later, PAGASA also issued their first advisory on the depression, giving it the local name Ditang. Tracking northward, the system intensified into a tropical storm, at which time it received the name Kirogi, before undergoing rapid intensification late on July3. Following this phase, the storm attained typhoon intensity and developed a well-defined 59km (37mi) wide symmetrical eye. Typhoon Kirogi attained its peak intensity early on July4 with winds of 155km/h (100mph 10-minute sustained) and a barometric pressure of 940mbar (hPa; 27.76inHg).
In Japan, hundreds of residents were evacuated as Typhoon Kirogi approached the country. Since the storm weakened considerably from its peak intensity, damage was much less than initially anticipated. In all, damages from the storm amounted to 15billion yen (2000 value, $140million USD) and 3 confirmed fatalities.[9][10]
On July 2, a low pressure area formed north west of the Philippines and became a tropical depression on July 3 and started to drift northward, becoming a storm on the 5th and a typhoon on the 6th. Kai-tak continued northward, hitting Taiwan on the 9th. Kai-tak dissipated on the 11th over the Yellow Sea. It was named after Hong Kong's old international airport, Kai Tak Airport.
The combined effects of Kai-tak and Tropical Depression Gloring led to the collapse of a large garbage pile, devastating a scavenger community with 300shanty homes near Manila. At least 218people died in the avalanche – some of whom were decapitated by machinery – and at least 73 others were injured.[11]
Clouds from TD Gloring (07W) affected Northern Luzon, Central Luzon, Southern Luzon, Bicol Region, and Parts of Visayas, but no damage or casualties were reported.
On July 13 an area of low pressure formed over Luzon and moved north west, and strengthened into a tropical depression on July 14.Tropical Depression 08W made landfall over Yangjiang, Guangdong, China on July 17 and dissipated inland.
On July 13 a cluster of thunderclouds grouped together to form a low pressure area. On July 14 it started to organize and slowly became a tropical depression on July 19, and quickly intensified into a tropical storm. On July 22 convection was displaced to south of the storm's center due to high wind shear, and caused it to dissipate.
JTWC treated 10W and 11W as separate depressions, although PAGASA and JMA both considered them the same system. On July 25, 11W became Severe Tropical Storm Bolaven.
On July 17, a disturbance with a large area of rotation formed south east of the Philippines. On July 24, favorable conditions allow the disturbance to quickly organize so it became a tropical depression the next day.
Damage of the flooding brought by the extratropical remnants of Bolaven in Primorsky Krai exceeded 600 million rubles ($20 million, 2000 USD).[12]
The remnants of Tropical Storm Upana encountered a favorable environment just west of the dateline, and they formed Tropical Depression 12W. The depression strengthened into Tropical Storm Chanchu. The name Chanchu, submitted by Macau, is a Chinese word for pearl. Chanchu moved north, and had dissipated by July 30.
Meteorologist Gary Padgett suggested that there was good evidence Chanchu was actually a regeneration of Upana. The official policy is that dateline crossers keep their name. However, there was supposedly some doubt at the time, so Chanchu and Upana were officially treated as distinct tropical cyclones. Also, since Upana had dissipated several days earlier, and the Joint Typhoon Warning Center had already assigned a new number for the system, Gary Padgett deemed it likely that the Japan Meteorological Agency's decision to rename the cyclone was the best choice. Also, a scatterometer pass near 0500 UTC on July 23 indicated an open wave with no closed circulation,[13] evidence that Upana had fully dissipated before restrengthening.
On July 29, a cluster of thunderstorms quickly formed into a low pressure area, which became Tropical Depression 13W on August 1. Favorable conditions allowed the system to rapidly intensify, and it was named Jelawat. On August 2, it reached its peak intensity as a Category 4 typhoon. On August 3, Jelawat weakened into a category 2 typhoon due to unfavorable wind shear. On August 6, Jelawat restrengthened into a category 3 typhoon due to more favorable conditions, and started to develop a large eye which was 60 kilometers across. Weak steering winds soon caused Jelawat to move slowly from August 7 to August 8. On August 7, Jelawat underwent an eyewall replacement cycle for 4 hours, and began to display annular characteristics, with a large, symmetric eye 170 kilometers across surrounded by a thick ring of intense convection. After developing a large, symmetric eye, Jelawat restrengthened from a category 1 typhoon to a category 2 typhoon, but soon weakened back to a category 1 typhoon as it encountered wind shear. It made landfall at southern Shanghai and rapidly weakened.
Typhoon Ewiniar developed on August 9. It strengthened into a typhoon while moving northward. Ewiniar weakened and eventually curved east-northeastward. The typhoon re-intensified, but dissipated on August 18.
A tropical disturbance developed in the Western Pacific Ocean along the eastern periphery of the monsoon trough in mid-August. Located at 33° north, it steadily organized, and became Tropical Depression Sixteen-W on August 15 while located 1700miles to the northwest of Honolulu, Hawaii. It moved eastward along the west- east oriented surface pressure trough, and crossed the International Date Line later on the 15th.[14] Warmer than usual water temperatures allowed the system to intensify despite its unusually high latitude, and it became Tropical Storm Wene on the 16th. It quickly attained a peak intensity of 50mph, but weakened due to cooler waters and wind shear. Wene continued to weaken, and dissipated when the storm merged with an extratropical cyclone.
As a depression, Wene was the first western Pacific tropical cyclone to cross the dateline since the 1996 season, and the most recent to do so until Tropical Storm Omeka in the 2010 season. The name Wene is Hawaiian for "Wayne".
Tropical Depression 17W existed from August 17 to August 18.[15] It did not make landfall and it dissipated quickly. No victims were recorded during the storm's short lifespan.
On August 14, a low pressure area formed south of the Mariana islands and started to organize. On August 17 the low pressure area became a tropical depression and as it tracked northwestward, becoming a tropical storm on the 18th and a typhoon on the 19th. Favorable conditions allow Bilis continued to intensify to a super typhoon on the 21st, and it struck the southeastern coast of Taiwan as a Category 5 typhoon on the 22nd. It weakened slightly to a 140 miles per hour (230km/h) typhoon while crossing the country, and hit China on the 23rd. Significant rainfall fell across Taiwan, with up to 949 millimetres (37.4in) recorded across northeast sections of the mountainous island.[16] Bilis was responsible for 17 deaths and $133.5million in damage on Taiwan. The flooding was significant and an unknown number of people drowned in the flooding.
On August 19, a low-pressure area formed west of the Philippines. Favorable conditions allow the low-pressure area to strengthen into a tropical depression on August 20. Kaemi made landfall over Vietnam on August 21, and it was reported that tropical storm Kaemi killed 14 people in Vietnam.[17]
On August 24 a large area of disturbed weather formed south of the Philippine sea. Prapiroon killed 75 people in total and caused $6 billion in damages in Korea, China and the Philippines.
The origins of Maria appeared to originate from the inland remnants of Typhoon Bilis, which was pulled south due to the Fujiwhara effect between Typhoon Prapiroon. The low pressure area entered the South China Sea as it drifted south over Hong Kong on August 27. As it was pulled south to the South China Sea, it quickly strengthened into a tropical storm on August 30. Maria made landfall on September 1 east of Hong Kong.
Typhoon Saomai developed on September 2. It strengthened while heading westward and reached typhoon status. Later in its duration, the typhoon turned northwestward and the PAGASA named it Osang. Eventually, Saomai was classified as a super typhoon, peaking with winds of 175km/h (110mph). Thereafter, the typhoon weakened before making landfall in South Korea. It dissipated shortly thereafter.
On September 6, a monsoonal trough quickly spawned an embedded depression that became a tropical storm on September 9. However, due to the Fujiwhara effect, the much stronger system, Typhoon Saomai dragged Bopha approximately 1,550 kilometers south, and weakened Bopha from September 9-11. The remnants of Bopha continued to move eastwards as it became Sonamu, on September 15.
Typhoon Wukong developed in the South China Sea on September 6. It was also named Maring by PAGASA. Wukong strengthened into a typhoon prior to landfall in Hainan and northern Vietnam. The storm dissipated on September 10.
Severe Tropical Storm Sonamu developed on September 15 from the remnants of Bopha. It headed east-northeastward and then north-northeastward, peaking with winds of 100km/h (65mph). By September 18, Sonamu dissipated near Hokkaido.
On September 14, a low-pressure area formed near the southern Marshall Islands. Favorable conditions allowed the low to strengthen into a tropical depression on September 17, and to intensify into a typhoon early on September 20. Shanshan reached peak intensity on September 21 as a Category 4 super typhoon. Due to the Fujiwhara effect, Shanshan was weakened by an extratropical cyclone located south of Kamchatka Krai, and Shanshan merged with it and collapsed into a single extratropical cyclone.
Tropical Storm 27W developed on September 28. It moved northeastward and peaked with winds of 65km/h (40mph). The storm eventually weakened and dissipated on September 30.
Typhoon Yagi developed on October 22. It was also named Paring by PAGASA. Peaking as a typhoon with winds of 130km/h (80mph), Yagi executed a cyclonic loop near the Ryukyu Islands. It then began weakening and dissipated near Taiwan on October 26.
On October 27, Typhoon Xangsane hit southern Luzon of the Philippines. It turned to the north over the South China Sea, and after strengthening to a 100mph typhoon it hit Taiwan. Xangsane dissipated on Nov. 1st, after causing 181 casualties, 83 of which were from the crash of Singapore Airlines Flight 006 the previous day on October 31, 2000.
On November 2, Tropical Storm Bebinca hit the central Philippines. It strengthened to a severe tropical storm and reached a peak of 60knot winds while crossing the archipelago, due to the contraction of the wind field. Bebinca continued northwestward, eventually dissipating over the South China Sea on the 8th after killing 26 people.[18] Severe Tropical Storm Bebinca made a direct hit over the capital city of Manila, with the center of the storm passing directly over it. Although other such storms, such as Typhoon Vera in 1983 and Typhoon Angela in 1995, crossed Metro Manila and brought typhoon-force winds to the city of Manila itself, Bebinca was the first storm to have made a direct hit in the city since Severe Tropical Storm Colleen in 1992 which passed over the city at tropical storm level, and the strongest to pass directly over Manila since Typhoon Patsy in 1970.
Tropical Depression 32W developed near Luzon on November 8. It turned northward and later east-northeastward. The depression dissipated on November 10.
On November 23, 2000 a low pressure area together with inter-tropical convergence zone developed into a tropical depression. Later that day, JTWC announced that it became a tropical storm. It had maximum of winds of 75 km/h near the center, and a pressure of 990 mbar. It then killed 48 people from the heavy rains which caused widespread flooding. The storm dissipated on December 7.
Typhoon Soulik formed to the east of the Philippines on December 28, 2000. It strengthened into a category 3 typhoon with a central pressure of 955 mbar on January 2. It finally dissipated on January 4, 2001.
Storm names
Within the North-western Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names.[20] The Japan Meteorological Agency's RSMC Tokyo— Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65km/h, (40mph).[21] While the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N even if the cyclone has had an international name assigned to it.[20] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[21] Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray.
International names
During the season 23 named tropical cyclones developed in the Western Pacific and were named by the Japan Meteorological Agency, when it was determined that they had become tropical storms. These names were contributed to a list of a 140 names submitted by the fourteen members nations and territories of the ESCAP/WMO Typhoon Committee. All of these names were used for the first time this year.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. This is the same list used for the 1996 season. This is the last season that the PAGASA uses its own naming scheme that starts in Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). The 2001 season is the official start of their new naming scheme that starts with the English Alphabet. Names that were not assigned are marked in gray.
Season effects
This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 2000. It will include their intensity, duration, name, areas affected, deaths, and damage totals. Classification and intensity values will be based on estimations conducted by the JMA. All damage figures will be in 2000USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical cyclone.
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 destructive and deadly season, although it was near-average in terms of activity with a total of 23 named storms, 15 typhoons, and six super typhoons. Compared to the previous season, more typhoons inflicted damage across several countries, particularly China and the Philippines, some of which made landfall at higher intensities. The ratio of intense typhoons to all typhoons is at 0.73, the highest since 1970.
The 2001 Pacific typhoon season was an average season with twenty-six named storms, sixteen typhoons and three super typhoons, with a near normal Accumulated Cyclone Energy (ACE) of 307.3 units. It ran year-round in 2001, with most tropical cyclones in the northwestern Pacific Ocean tending between May and November.
This timeline documents all of the events of the 2005 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean during the year. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical depressions that form in the basin were given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). If a depression intensified into a tropical storm, it would be assigned a name by the Japan Meteorological Agency (JMA). In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigned names to tropical cyclones which were in their area of responsibility.
The 1987 Pacific typhoon season was a below average season, though it featured a relatively high amount of typhoons. It had no official bounds; it ran year-round in 1987, but most tropical cyclones formed between May and November. Tropical storms that formed in the entire basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The 1980 Pacific typhoon season was a slightly-below average season when compared to the long-term average, though it featured several intense storms. It ran year-round in 1980, but most tropical cyclones formed between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 28 tropical depressions formed this year in the Western Pacific, of which 24 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. Beginning in March, tropical cyclones formed in each subsequent month through December. Of the 24 named storms, 15 storms reached typhoon intensity, of which 2 reached super typhoon strength.
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 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 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.
This timeline documents all of the events of the 2009 Pacific typhoon season which was the period that tropical cyclones formed in the Western Pacific Ocean during 2009, with 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.
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 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 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.
Most of the tropical cyclones of the 2013 Pacific typhoon season formed between May and November of that year. The scope of this article is the Pacific Ocean north of the equator, between 100°E and the International Date Line. Tropical storms which form in the Western Pacific basin are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions forming in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility, but these names are not in common use outside the Philippines.
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.
This timeline documents all of the events of the 2012 Pacific typhoon season. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. During the season, 34 systems were designated as tropical depressions by either the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. Since the JMA runs the Regional Specialized Meteorological Centre (RSMC) for the Western Pacific, they assigned names to tropical depressions which developed into tropical storms in the basin. PAGASA also assigned local names to systems which are active in their area of responsibility; however, these names are not in common use outside of the Philippines.
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.
The 2023 Pacific typhoon season was the fourth consecutive below-average season and became the third-most inactive typhoon season on record in terms of named storms, with just 17 named storms developing, only ahead of 2010 and 1998. Despite the season occurring during an El Niño event, which typically favors activity in the basin, activity was abnormally low. This was primarily due to a consistent period of negative PDO, which typically discourages tropical storm formation in this basin. The season was less active than the 2023 Atlantic hurricane season in terms of named storms, the fourth such season on record, after 2005, 2010 and 2020. The season's number of storms also did not exceed that of the 2023 Pacific hurricane season. Only ten became typhoons, with four strengthening further into super typhoons. However, it was very destructive, primarily due to Typhoon Doksuri which devastated the northern Philippines, Taiwan, and China in July, becoming the costliest typhoon on record as well as the costliest typhoon to hit mainland China, and Typhoon Haikui in September, which devastated China, Taiwan, and Hong Kong. The season was less active in Southeast Asia, with no tropical storm making landfall in mainland Vietnam.
Tropical Storm Kirogi, known in the Philippines as Tropical Storm Tino, was a weak tropical cyclone that affected the Philippines and Vietnam. The thirty-ninth tropical depression, twenty-fifth tropical storm, and fourteenth system to affect Vietnam in the 2017 Pacific typhoon season, Kirogi formed as a tropical depression on November 16 in the Moro Gulf. After being given the local name Tino by the PAGASA, it entered the South China Sea, intensifying into a tropical storm and receiving the name Kirogi from the Japan Meteorological Agency on November 18. Continuing westwards, it weakened into a tropical depression before making landfall near Cam Ranh Bay in Vietnam on the next day, dissipating shortly afterwards. Kirogi's remnants later contributed to the formation of Cyclone Ockhi.
During 2023, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. They were named by various weather agencies when they attained maximum sustained winds of 35 knots. Throughout the year, a total of 115 systems formed, with 79 of them being named. The most intense storm this year was Typhoon Mawar, which had a minimum pressure of 900 hPa (26.58 inHg). The deadliest tropical cyclone of the year was Storm Daniel, which killed at least 5,591 people in Libya, Greece, Turkey, and Bulgaria. Meanwhile, the costliest tropical cyclone was Typhoon Doksuri which caused at least $28.4 billion (USD) worth of damage in China, the Philippines and Taiwan, becoming the costliest on record outside the Atlantic Ocean basin. Among this year's systems, thirty became major tropical cyclones, of which ten intensified into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). This year, for the first time on record, at least one such Category 5 system formed in each tropical cyclone basin: Typhoons Mawar, Saola, and Bolaven in the western Pacific Ocean, Hurricanes Jova and Otis in the eastern Pacific, Hurricane Lee in the Atlantic, Cyclone Mocha in the North Indian Ocean, Cyclone Freddy in the southwest Indian Ocean, Cyclone Ilsa in the Australian region, and Cyclone Kevin in the South Pacific. The accumulated cyclone energy (ACE) index for the 2023, as calculated by Colorado State University (CSU) was 857.4 units, which was above the 1991-2020 mean of 770.2 units.
