The 1973 Pacific typhoon season, in comparison to the two years preceding it, was a below average season, with only 21 named storms and 12 typhoons forming. However, it featured Typhoon Nora, which ties Typhoon June of 1975 for the second strongest typhoon on record. It has no official bounds; it ran year-round in 1973, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1973 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. 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.
25 tropical depressions formed this year in the Western Pacific, of which 21 became tropical storms. 12 storms reached typhoon intensity, of which 3 reached super typhoon strength. [1]

Tropical Storm Wilda formed as a disturbance east of the Philippines. It traveled northwest and became a tropical depression as it made landfall on Luzon on June 30. It crossed the island, and became a tropical storm as it entered the South China Sea on 1 July. It traveled north and made landfall in southern China on the 3rd. The remnants of Wilda dissipated inland a few days later.

Tropical Storm Billie, which developed on July 12 east of the Philippines, rapidly strengthened on the 14th and 15th to a 150 mph super typhoon. It tracked due north, fluctuating in intensity for the next 3 days. A building ridge over the Sea of Japan forced Billie to the northwest, where it weakened greatly, first to a tropical storm on the 18th, then to a tropical depression on the 19th as it passed over northeastern China. The storm dissipated on the 20th.

Typhoon Ellen formed as a disturbance on July 16 in the vicinity of Okinotorishima, [lower-alpha 1] from a trough in the convergence zone trailing to the southeast of Typhoon Billie the day before. [4] Its circulation closed up by 17 July, [4] and at 0900 JST (0000 UTC) on the following day, the JMA upgraded it to a tropical storm. [5] Due to its sluggish, erratic movements, Shikoku and Kyushu received heavy rains between July 23 and July 26. This contributed to the above-average monthly precipitation for July 1973 in southern Shikoku and eastern Kyushu, when the rest of Japan was suffering from droughts. [6]

The monsoon trough spawned a tropical depression east of the Philippines on October 1. Under weak steering currents, it meandered westward, where favorable conditions allowed for it to strengthen, first to a tropical storm on the 2nd, then to a typhoon on the 3rd. Nora continued to the northwest, and explosively deepened on the 5th and 6th to a 185 mph super typhoon. At the time, it had a minimum central pressure of 875 millibars, the lowest pressure on record at the time and currently tied for 9th. The typhoon weakened as it headed to the northwest, and struck northeastern Luzon on the 7th as a 115 mph typhoon. Nora continued to the northwest, weakening to a minimal typhoon as it hit southeast China on the 10th. The typhoon caused 18 fatalities, with over $2 million in damage.

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 1969 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.).
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 1973. It will include their intensity, duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. Classification and intensity values will be based on estimations conducted by the JMA, however due to lack of information around this time sustained winds were recorded by the JTWC. All damage figures will be in 1973 USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.

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 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 252.9 units.
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 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.
The 1993 Pacific typhoon season was the most active season for the Philippines, seeing a total of 32 storms forming or entering their area of responsibility. Overall, it was an average season, spawning 28 tropical storms, 15 typhoons and three super typhoons. The season had no official bounds; it ran year-round in 1993, 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 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.
The 1983 Pacific typhoon season was the latest start for a Pacific typhoon season on record, and also slightly below-average in terms of named storms. It ran year-round in 1983, but all 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 32 tropical depressions formed this year, of which only 23 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. Additionally, 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. This year, a total of 23 storms were named this way.
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.
The 1977 Pacific typhoon season was one of the least active Pacific typhoon seasons on record, with only 19 tropical storms forming. It was also the second of three known typhoon seasons during the satellite era to not produce a Category 5-equivalent super typhoon, sandwiched between the 1974 and 2017 seasons. The season's first storm, Severe Tropical Storm Patsy, formed on March 23 and the last, Typhoon Mary, dissipated on January 2, 1978. With Mary spanning two calendar years, it became the fourth typhoon to do so since 1945. Since then, two other typhoons have achieved this feat.
The 1976 Pacific typhoon season has no official bounds; it ran year-round in 1976, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1975 Pacific typhoon season was one of the deadliest tropical cyclone seasons on record, with nearly 229,000 fatalities occurring during the season. It had no official bounds; it ran year-round in 1975, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1974 Pacific typhoon season was the first season on record to not feature a Category 5 equivalent super typhoon; a feat later repeated by the 1977 and 2017 seasons. Even so, the season was overly active, with 32 tropical storms and 16 typhoons being developed this year. It has no official bounds; it ran year-round in 1974, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1969 Pacific typhoon season was the fourth least-active season on record. The season had no official bounds; it ran year-round in 1969, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1968 Pacific typhoon season has no official bounds; it ran year-round in 1968, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1967 Pacific typhoon season was one of the most active Pacific typhoon seasons on record, witnessing the formation of 35 tropical storms during the season. It began on January 1, 1967, though most storms usually form between June and December within the basin. The first storm of the season, Ruby, formed on January 28 west of the Philippines. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1967 Pacific hurricane season. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) were given a numerical designation with a "W" suffix, and any storms reaching 1-minute sustained winds of over 40 mph were given a name. 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.
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.
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.
This timeline documents all of the events of the 2011 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean in 2011. Most of the tropical cyclones formed between May and November 2011. 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 (JMA).

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.
