Typhoon Violet, international code 197005, international name VIOLET, 1970 Northwest Pacific typhoon. Formed: 1970-08-06 00:00:00, ended: 1970-08-09 06:00:00. Peak intensity: Tropical Storm, minimum central pressure: 992 hPa, max wind: 20m/s.
Typhoon Violet at 1970-08-06 00:00:00 at 15°N, 124°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 20 m/s (~72 km/h) and a minimum central pressure of 992hPa, recorded at 1970-08-06 18:00:00.
1970-08-09 06:00:00 After, Typhoon Violet gradually weakened and was numbered off on 1970-08-09 06:00:00 was numbered off; its lifecycle recorded 14 track points.
Typhoon Violet (197005) 的生命周期较短, 从 formed至消散历时约3天半. 其路径整体呈现稳定的NW toward MovingTrend, 未出现明显的转 toward 或停滞现象. 初始阶段, 系统位 at Philippines以E洋面 (15°N, 124°E) , 随后持续 toward NW direction穿越巴士海峡附近海域. 通过坐标序列分析, 该Typhoon 在The latitude上由15°N逐步N移至21.7°N, During上由124°EW移至112.5°E, 平均移速较为均匀. 值得注意的是, 该系统全程无Landfall记录, 始终在海上活动, 最终在S海N部海域减弱消散. track points分布显示, 其Moving轨迹平滑, 受大尺度引导气流影响显著, 未受到复杂地形或局部环流的剧烈干扰.
Violet的Intensity变化具有典型的“快速增强后迅速减弱”特征. 系统在 formed初期为Nameless, wind speed12m/s. 在 formed后的18h内, intensity 稳步提升, at 1970年8月6日18:00达到巅峰状态, 升级为Tropical Storm, max wind 录得20m/s. 然而, 巅峰状态维持Time极短, 仅约6h后, 即8月7日06:00, 系统便减弱回Nameless, wind speed降至17m/s. 此后直至消散, 其Intensity一直维持在Nameless级别, wind speed在15m/s至17m/s之间波动, 未再重新加强. 这种短暂的强盛期表明, 尽管初始环境有利 at 其发展, 但后续可能遭遇了垂直风切变增大或海温降低等不利条件, 导致对流结构无法维持.
In the history, in 1967, the Violet in 1996 developed to Super Typhoon, in 1964 to Typhoon level, in 1976 also reached Severe Tropical Storm level. In contrast, in 1970, the Violet only for Tropical Storm level, max wind 20m/s, is the weakest of the Intensity listed in the same name Typhoon.
