The SummaryTyphoon Oliwa (international code 199716) is a 1997 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 71m/s, minimum central pressure 915hPa, not in China Landfall, 1997-09-17 was numbered off, recording 54 track points.
Typhoon Oliwa, international code 199716, international name OLIWA, 1997 Northwest Pacific typhoon. Formed: 1997-09-04 00:00:00, ended: 1997-09-17 06:00:00. Peak intensity: Super Typhoon, minimum central pressure: 915 hPa, max wind: 71m/s.
Typhoon Oliwa at 1997-09-04 00:00:00 at 13.1°N, 179.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 71 m/s (~256 km/h) and a minimum central pressure of 915hPa, recorded at 1997-09-09 18:00:00.
1997-09-17 06:00:00 After, Typhoon Oliwa gradually weakened and was numbered off on 1997-09-17 06:00:00 was numbered off; its lifecycle recorded 54 track points.
Typhoon Oliwa (199716)'s life began at 00:00 on September 4, 1997 in the Northwest Pacific Ocean, at the initial position at 13.1°N, 179.4°E. During the period formed from early September 7th, the systemined NamelessIntensity, overall presenting a stable WNTrend, latitude slowly rising from 13.1°N to 17°N, length significantly shifted from 179.4°E to 165.3°E. As the system gradually enhanced, its Moving pathwayined a relatively flat W trend between September 8th and September 12th, transcending the international date shift line to W broad surface.
Co-ordinate data show that from 21.3°N, 141.4°E on September 12 to 37.7°N, 138.4°E on September 17, the latitude of the system rapidly increased by N over 16 latitudes, while the length changes were relatively slowed and accompanied by a small E fall. This suggests that after the system reached lat 24 degrees near, influenced by the high latitude W wind belt guided airflow, the path turned from W to NE, and eventually dispersed from the ocean to E in Japan.
Oliwa’s Intensity evolution shows a typical “fast enhancement – peak maintenance – gradual weakening” characteristic.On September 7, after upgrading to Tropical Storm, the system Go to rapid enhancement period.In just 48h, max wind increased from 23m/s to 46m/s, and at September 10 reached Super Typhoon intensity with max winds of 71m/s. Two days later, the systemined a 71m/speak intensity between 18.6°N and 19.5°N, showing extremely strong structural stability.
From September 12, as the latitude increases and the possible vertical wind shift increases, the Typhoon begins to weaken. Max Wind gradually drops from 64m/s to 48m/s on September 14, the level falls back to Severe Typhoon. Go to High latitude waters, the effect of heat decrease is significant, the 16th of September decreases to Typhoon , finally at September 17th morning at 37.7 degrees weakened into Nameless and ends the observation. As the 16th Typhoon in 1997, its 71m/s peak wind speed reflects the intensity of Northwest Pacific Typhoon activity at the time, despite the lack of specific air pressure values, but extremely high speedwind indicators are sufficient to prove the strong momentum of its core flow system.
