The SummaryTyphoon Nadine (international code 197414) is a 1974 Northwest Pacific typhoon; peak intensity Severe Tropical Storm, max wind 25m/s, minimum central pressure 980hPa, not in China Landfall, 1974-08-18 was numbered off, recording 14 track points.
Typhoon Nadine, international code 197414, international name NADINE, 1974 Northwest Pacific typhoon. Formed: 1974-08-15 00:00:00, ended: 1974-08-18 06:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 980 hPa, max wind: 25m/s.
Typhoon Nadine at 1974-08-15 00:00:00 at 16.4°N, 125.6°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 25 m/s (~90 km/h) and a minimum central pressure of 980hPa, recorded at 1974-08-16 00:00:00.
1974-08-18 06:00:00 After, Typhoon Nadine gradually weakened and was numbered off on 1974-08-18 06:00:00 was numbered off; its lifecycle recorded 14 track points.
Typhoon Nadine (197414)'s life cycle is shorter, from formed to dispersed for about 3 and a half days. Its path overall presents a significant 'NW-N-NE' turn toward feature, belonging to the typical ocean-pelled line path. Initial phase (August 15 00 to 12) , system position at Philippines at E surface (16.4°N, 125.6°E near) , led by the sub-tropical high pressure S side E air flow, the main toward W direction rapid Moving, length rapidly increases in about 5.2 degrees within 12h. Then, with the latitude slightly S pressure to 15.5°N, the path begins to take a critical turn. From August 15 18th, Moving direction gradually turns to NW, and at around August 16 06 at reach
Go to August 16 at 12 a.m., Typhoon accelerated toward NE, the latitude rapidly climbed from 18°N to 31.4°N, the length then stabilized in the lng 140°-141° interval after shaking toward W. Thro the process, the Typhoon did not landfall any land, was always active on the open ocean surface, and eventually at August 18 at 06 a.m. at 31.4°N, 139.7°E near decreased dispersion.
在Intensity变化方面, Nadine经历了“快速增强-短暂巅峰-持续减弱”的过程. formed初期为Nameless, wind speed15m/s; 在 toward NWMoving过程中迅速加强, 仅用18h便发展为Severe Tropical Storm, 并 at 8月16日00时达到peak intensity, max wind 25m/s. 然而, 其巅峰状态维持Time极短, 仅6h后便开始减弱. 自8月16日12时起, 尽管The latitude仍在增加, 但中心wind speed回落至20m/s并降级为Tropical Storm, 随后进一步 weakened into Nameless, 直至消散. 值得注意的是, 在整个生命周期中, 气压数据缺失, 仅能依据wind speed判断Intensity等级.
Looking back on the historical record, Nadine had reached the Super Typhoon level in 1971, intensity far exceeding this year; while the same name Typhoon peak intensity in 1968, 1965 and 1960 was Severe Tropical Storm, with Nadine in 1974. this shows that in the naming sequence 'Nadine', the system in 1974 is at the medium weak level, and by at its higher latitudes rapidly weakened, does not pose a direct threat to the surrounding land, reflecting the diversity and uncertainty of the named Typhoon Intensity.
