1973, 1974, 1975, 1976, 1977

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.

Contents

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.

Some of the notable storms here are Typhoon Nina, which caused the Banqiao Dam flood, which resulted in approximately 126,000 people dead, and Typhoon June, which was the strongest storm on record with a pressure of 875 mbar, until beaten by Typhoon Tip in 1979 with 870 mbar.

On November 15, a disturbance was first detected in the monsoon trough well to the southeast of Guam, before finally developing into a tropical depression on November 16. Moving erratically, the depression was then later upgraded by the JTWC to a tropical storm. During November 17-18 June then began to explosively deepen as it moved to the north in response to a weakness in the ridge caused by a nearby trough, deepening as much as 52 mbars in under 12 hours, and 90 mbars in 24 hours. Early on November 19, a US Air Force reconnaissance aircraft measured a near record low pressure of 875mb just off the eyewall, indicating it could have been stronger. Shortly after the near-record peak, June then began a eyewall replacement cycle, becoming one of the first recorded cases of triple eyewalls. [5] It then began to slowly weaken as it moved northwest, weakening below category 5 status early on November 21, before beginning to recurve to the northeast as it began extratropical transition, achieving a forward speed as high as 70mph. June finally became extratropical late on November 23. The remnants then became a powerful extratropical storm, with a pressure of 960mb before it was last noted over far northeastern Siberia. [6]

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 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1979 season. This is the same list used for the 1971 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.). Names that were not assigned/going to use 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 1975. 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, the JTWC, and/or PAGASA. Peak wind speeds are in one-minute sustained standards unless otherwise noted. All damage figures will be in 1975 USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.

<span class="mw-page-title-main">2005 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">2003 Pacific typhoon season</span>

The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.

<span class="mw-page-title-main">2000 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1998 Pacific typhoon season</span>

The 1998 Pacific typhoon season was the least active Pacific typhoon season on record, until it was surpassed 12 years later. It would produce 16 tropical storms, 8 strengthening into typhoons. 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 1998 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.

<span class="mw-page-title-main">1997 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

The 1997 Pacific typhoon season was a record-breaking season featuring 11 tropical cyclones reaching super typhoon intensity, tying the record with 1965 with the most violent tropical cyclones globally. It has no official bounds; it ran year-round in 1997, 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 1992 Pacific typhoon season is the fourth consecutive above-average season, producing 31 tropical storms, 16 typhoons and five super typhoons. It had no official bounds; it ran year-round in 1992. Despite this, 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.

<span class="mw-page-title-main">1991 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1990 Pacific typhoon season</span>

The 1990 Pacific typhoon season was another active season. It has no official bounds; it ran year-round in 1990, 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.

<span class="mw-page-title-main">1986 Pacific typhoon season</span>

The 1986 Pacific typhoon season was an above average season, featuring 29 named storms, 19 typhoons, and 3 super typhoons. It has no official bounds; it ran year-round in 1986, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. Tropical Storms formed in the entire west pacific 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.

<span class="mw-page-title-main">1985 Pacific typhoon season</span>

The 1985 Pacific typhoon season was a slightly above average season in terms of named storms, though most storms were weak and short-lived. The season had 28 named storms, 15 typhoons and 1 super typhoon. It ran year-round, thus ending the two-season run which began in 1983 that only had tropical cyclones forming 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 57 tropical depressions formed this year, of which only 28 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. This made the season well above average. Additionally, tropical depressions that enter or form in the Philippine area of responsibility were 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 17 storms were named this way.

<span class="mw-page-title-main">1983 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1980 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1979 Pacific typhoon season</span>

The 1979 Pacific typhoon season featured the largest and most intense tropical cyclone recorded globally, Typhoon Tip. The season also used both male and female names as tropical cyclone names for the first time. Additionally, the season was slightly below-average in terms of tropical cyclone activity, with only 24 storms, 12 typhoons, and 4 super typhoons developing. The season had no official bounds; it ran year-round in 1979, 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.

<span class="mw-page-title-main">1977 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1970 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1974 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">1972 Pacific typhoon season</span>

The 1972 Pacific typhoon season was an above average season, producing 31 tropical storms, 24 typhoons and 2 intense typhoons.
