The name Ruping was used for seven tropical cyclones by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and its predecessor, the Philippine Weather Bureau, in the Western Pacific Ocean.
Due to the severe loss of life and destruction brought by its 1990 iteration, the name Ruping was retired after 1990. It was replaced by Ritang, which was only used once:
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 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 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 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 name Isang has been used for sixteen tropical cyclones worldwide: fifteen times by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) in the Western Pacific, and once by the Météo-France in the South-West Indian Ocean.
The name Bising has been used for 14 tropical Cyclones in the Philippine Area of Responsibility by PAGASA in the Western Pacific.
The name Openg was used for nine tropical cyclones in the Philippines by the PAGASA in the Western Pacific Ocean.
The name Luding was used for ten tropical cyclones by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and its predecessor, the Philippine Weather Bureau, in the Western Pacific Ocean.
