Typhoon Peter (1997)
The 1997 Pacific typhoon season was a record-breaking season featuring eleven tropical cyclones reaching super typhoon intensity, tying the record with 1965 Pacific typhoon season, 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 Pacific typhoon season, 1988. Its extremely high activity produced highest ACE index ever index recorded in a single tropical cyclone season. In addition, this season had ten Saffir-Simpson scale, Saffir-Simpson Category 5-equivalent tropical cyclones, the most ever recorded, even greater than the 2005 Atlantic hurricane season, and 2020 Atlantic hurricane season, for Category 4, which had nearly half of the amount. 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-ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Ivan
Typhoon Ivan, known in the Philippines as Super Typhoon Narsing, was an extremely intense tropical cyclone that existed simultaneously with another storm of the same intensity, Typhoon Joan (1997), Typhoon Joan, in October 1997. Forming out of an area of disturbed weather on October 13, Ivan gradually intensified into a typhoon as it tracked steadily to the west-northwest. On October 15, the storm underwent Rapid deepening, rapid intensification and reached an intensity corresponding to Category 5 status on the Saffir–Simpson Hurricane Scale. Late on October 17, Ivan reached its peak strength with winds of and a barometric pressure of 905 hPa (mbar). Shortly thereafter, the typhoon began to weaken as it approached the Philippines. Ivan eventually made landfall in northern Luzon with winds of on October 20 before weakening to a tropical storm the next day.

Typhoon Oliwa
Typhoon Oliwa was one of a record eleven super typhoons in the 1997 Pacific typhoon season. Oliwa ( Hawaiian for Oliver) formed in the central Pacific Ocean on September 2 to the southwest of Hawaii, but it became a typhoon in the western Pacific. Oliwa explosively intensified on September 8, increasing its winds from 85 mph to 160 mph (140 to 260 km/h) in a 24‑hour period. Afterward, it slowly weakened, and after passing east of Okinawa, Oliwa turned northeast and struck Japan with winds of . There, it affected 30,000 people and killed 12; thousands of houses were flooded, and some were destroyed. Offshore South Korea, the winds and waves wrecked 28 boats, while one boat went missing with a crew of 10 people. Oliwa dissipated on September 19 in northern Pacific Ocean near the International Date Line. Meteorological history The origins of Typhoon Oliwa were from an unusually eastward extension of the monsoon trough in late August 1 ...

Tropical Storm Zita
Severe Tropical Storm Zita, known in the Philippines as Tropical Storm Luming, was a short-lived tropical cyclone that killed seven people throughout southern China in August 1997. Originating from a tropical disturbance over the South China Sea on August 19, Zita tracked westward as it quickly strengthened within a region of light wind shear, attaining winds of as it made landfall along the Leizhou Peninsula early on August 22. Maintaining this intensity, the storm made a second landfall in northern Vietnam later that day before rapidly weakening over land. The remnants of Zita were last noted over extreme northwestern Vietnam on August 24. Although a relatively weak system, Tropical Storm Zita caused significant damage in Southern China. There, seven people were known to have been killed by the storm and damage reached $433 million (1997 USD). However, a report from Dartmouth College states that 345 people were killed by the storm.

Typhoon Winnie (1997)
Typhoon Winnie, known in the Philippines as Super Typhoon Ibiang, was the most destructive tropical cyclone to impact the Chinese provinces of Zhejiang, Fujian, Jiangsu, and Shandong in 200 years. Originating from an area of low pressure over the Pacific Ocean on August 5, 1997, the system organized into a tropical depression. It headed northwestward, slowly strengthening into a tropical storm on August 9. Intensification became more rapid as conditions became more favorable, and Winnie reached typhoon strength on August 10. On August 12, 1997, Winnie became a Category 5-equivalent super typhoon, with peak 1-minute sustained winds of . Winnie then weakened and passed north of Taiwan, before making landfall in Eastern China at Category 1-equivalent typhoon strength on the August 18. Winnie continued northeast over land while weakening, bringing heavy rainfall before dissipating on August 23. Winnie is also tied with Typhoon Carmen in 1960 for having the ...

Typhoon Isa
Typhoon Isa was the first of a record eleven super typhoons to occur during the 1997 Pacific typhoon season. The second tropical cyclone of the season, Isa developed from a disturbance in the monsoon trough near the Caroline Islands on April 12. It moved erratically at first, though after attaining tropical storm status it curved westward due to the subtropical ridge to its north. Isa very gradually intensified, and on April 20 the typhoon reached peak 1-min winds of , as reported by the Joint Typhoon Warning Center; Japan Meteorological Agency reported maximum 10-min winds of . After turning northward, it accelerated to the northeast, and merged with a larger extratropical cyclone on April 24. Early in its duration, Isa caused light rainfall and moderate winds on Pohnpei. Later, a stationary rainband from the typhoon dropped heavy precipitation on Guam during its dry season. Damage in the Guam National Weather Service area of responsibility totaled $1 million (1997 USD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maximum Sustained Wind
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a certain distance from the center, known as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above mean sea level, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery is often used to estimate the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, an ...
