Typhoon Lucy (197412) 的生命史始 at 1974年8月8日00时, formedPosition位 at lat 17.4°N, 118.8°附近海域. 在初始阶段 (8月8日00时至18时) , 系统Moving极为缓慢, 主要呈现微弱的 toward N及 toward W漂移Trend, 经The latitude变化幅度极小, 表明其处 at 引导气流较弱的区域或受周围环流牵制明显. 自8月9日06时起, Typhoon Moving速度显著加快, direction转为稳定的NE toward Moving. 从坐标序列分析, 其路径呈现出明显的“先缓后快, 持续N上”的特征. 在8月9日至8月11日期间, 纬度从19.4°N迅速推进至25.5°N, During则从119.2°E逐渐W退至118.3°E, 整体路径呈NNW走 toward . 直至8月12日00时消散, 该系统始终保持在海上活动, 全程无Landfall记录, 未对陆地造成直接冲击.
In terms of intensity, the Typhoon Lucy overallined a weaker level, the highest intensity during the entire life cycle is only Nameless. data showed that its Max Wind reached a peak of 17m/s on August 9 at 12 p.m., followed by the Go to fluctuation decrease period. August 9 at 06 am to August 10 at 12 p.m., wind speedined between 15-17m/s, for a relatively strong stage; after that wind speed gradually declined, to August 11 at 12 p.m. to 10m/s, and finally ended life history at 12 p.m. at 10m/swind speed. by at lack of air pressure data, can only be judged by wind speed its structure loose, not significantly enhanced.
Historical records show that the same-name Typhoon “Lucy” peak intensity in 1965, 1968, 1971 and 1977 reached the Super Typhoon level, with extremely strong destruction potential. In comparison, the 1974 number Typhoon only stopped in the Nameless phase, max wind less than 20m/s, belonging to the typical weak tropical cycling process. This huge Intensity difference reflects the significant impact of the different years atmospheric background on the development of Typhoon, in 1974 Lucy may be affected by factors such as a larger vertical wind cut or sea temperature conditions, not being able to develop into a mature and strong wind system like the other years of the same name Typhoon.
