1997 Pacific typhoon season
typhoon season in the Pacific Ocean
The 1997 Pacific typhoon season was a record-breaking season featuring eleven tropical cyclones reaching super typhoon intensity, tying the record with 1965 with the most intense tropical cyclones globally, and was the ninth and last consecutive year of above-average tropical cyclone activity that started in 1988. Its extremely high activity produced the highest ACE index ever recorded in a single tropical cyclone season. In addition, this season had ten Saffir-Simpson Category 5-equivalent tropical cyclones, the most ever recorded in a single regional tropical cyclone season. The 1997–98 El Niño event was a contributing factor to this unusually high activity. Despite this, the season produced an average number of tropical storms, spawning 28 tropical storms.
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 first named storm, Hannah, developed on January 20 while the last named storm, Paka, dissipated on December 23. Tropical Storm Linda became the worst tropical cyclone to hit Vietnam, killing over 3,000 people.

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q869444. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997, 1965 and 1988.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
