The SummaryTyphoon Lucy (international code 197717) is a 1977 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 59m/s, minimum central pressure 920hPa, not in China Landfall, 1977-12-07 was numbered off, recording 39 track points.
Typhoon Lucy, international code 197717, international name LUCY, 1977 Northwest Pacific typhoon. Formed: 1977-11-28 06:00:00, ended: 1977-12-07 18:00:00. Peak intensity: Super Typhoon, minimum central pressure: 920 hPa, max wind: 59m/s.
Typhoon Lucy at 1977-11-28 06:00:00 at 6.8°N, 160°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 59 m/s (~212 km/h) and a minimum central pressure of 920hPa, recorded at 1977-12-03 18:00:00.
1977-12-07 18:00:00 After, Typhoon Lucy gradually weakened and was numbered off on 1977-12-07 18:00:00 was numbered off; its lifecycle recorded 39 track points.
Typhoon Lucy (197717) formed at Northwest Pacific远洋海域, 初始Position位 at 6.8°N, 160°E附近. 在生命史初期 (11月28日至12月1日) , 该系统维持NamelessIntensity, 整体呈现稳定的WNTrend, The latitude从6.8°N缓慢上升至8.8°N, During则由160°E大幅W进至140.6°E, 横跨约20个经度, 显示出深厚的低层引导气流作用.
After 2 December, as the system intensified into Tropical Storm and Typhoon, its Moving pathway occurred a significant reversal. After reaching Super TyphoonIntensity on 3 December, the pathway gradually shifted from pure W toward to NW toward, and at 5 December before at 18.8°N, 129.9°E reached the nearest W end. Then, influenced by the high-air W wind band or sub-tropical high-voltage shape changes, Typhoon occurred a noticeable reversal toward, the pathway turned to NE. From 5 December 18:00 to disperse, the center coordinates length from 134.1°E rapidly back to 152.9°E, latitudeined between 21°N-22°N zone, eventually weakened in the ocean area.
The system stagnated for up to 4 days in the Nameless phase, wind speedined at 15m/s. From 2 December 00:00, intensity began to increase significantly, in only 36h jumped from Tropical Storm (23m/s) to Super Typhoon (56m/s) , and at 3 December 12:00 to 4 December 06:00ined the peak wind speed of 56m/s, max wind had reached 59m/s, showing its core structure had been highly organized.
Compared with previously named Typhoon, Lucy's Intensity performance in 1977 was rather prominent. Compared to at 1974 Lucy only reached NamelessIntensity, the system in 1977 was more fully developed. At the same time, as with the LucyTyphoon in 1971, 1968 and 1965, it reached the Super Typhoon level, showing that the name 'Lucy' corresponded to many strong tropical cyclones in history. Despite peak intensity comparable, but in 1977 Lucy's life cycle was longer (about 9.5 days) and the pathway was large, reflecting the typical complexity of the late autumn Northwest Pacific Typhoon activity.
