The 2004 Pacific typhoon season was an extremely active season that featured the second-highest ACE ever recorded in a single season, second only to 1997, which featured 29 named storms, nineteen typhoons, and six super 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 2004, though most tropical cyclones typically develop between May and October. The season's first named storm and also the first typhoon, Sudal, developed on April 4, later was reached typhoon status two days later, and became the first super typhoon of the year three days later. The season's last named storm, Noru, dissipated on December 21.
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 1998 Pacific typhoon season was at the time the least active Pacific typhoon season on record, until the record was surpassed 12 years later, spawning 16 tropical storms and 8 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.
The 1996 Pacific typhoon season has no official bounds; it ran year-round in 1996, 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 1993 Pacific typhoon season has 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 ran year-round in 1991, although most tropical cyclones tended to form in the northwestern Pacific Ocean between May and November, 1991. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
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.
The 1985 Pacific typhoon season has no official bounds; it ran year-round in 1985, 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. 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.
The 1980 Pacific typhoon season has no official bounds; it ran year-round in 1980, 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. Tropical storms which 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.
The 1979 Pacific typhoon season featured the largest and most intense tropical cyclone recorded globally, Typhoon Tip. The season also experienced slightly above-average tropical cyclone activity. 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.
The 1978 Pacific typhoon season was a very active season that produced 31 tropical storms, 16 typhoons and one intense typhoon. It has no official bounds; it ran year-round in 1978, 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 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 1973 Pacific typhoon season 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 1972 Pacific typhoon season was an above average season, producing 31 tropical storms, 24 typhoons and 2 intense typhoons. It has no official bounds; it ran year-round in 1972, 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 1965 Pacific typhoon season has no official bounds; it ran year-round in 1965, 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 1957 Pacific typhoon season has no official bounds; it ran year-round in 1957, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December.

Typhoon Bess, known in the Philippines as Typhoon Susang, was responsible for the disappearance of a United States Air Force weather reconnaissance aircraft. Developing out of a poorly organized system on October 8 to the east of the Philippines, Bess featured two centers of circulation. Initially the southern low was monitored; however, a low to the north soon became the dominant center. Tracking generally west-northwestward, the storm gradually intensified before striking northern Luzon as a minimal typhoon on October 11. Temporary weakening took place due to interaction with land. After moving back over water the following morning, Bess regained typhoon intensity. This was short-lived though, as conditions surrounding the cyclone soon caused it to weaken. Now moving due west, the weakening storm eventually struck Hainan Island as a tropical storm on October 12 before diminishing to a tropical depression. The depression briefly moved back over water before dissipating in northern Vietnam on October 14.
