Typhoon Olive, international code 197801, international name OLIVE, 1978 Northwest Pacific typhoon. Formed: 1978-04-15 00:00:00, ended: 1978-04-26 18:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 955 hPa, max wind: 43m/s.
Typhoon Olive at 1978-04-15 00:00:00 at 3.5°N, 149°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 43 m/s (~155 km/h) and a minimum central pressure of 955hPa, recorded at 1978-04-23 00:00:00.
1978-04-26 18:00:00 After, Typhoon Olive gradually weakened and was numbered off on 1978-04-26 18:00:00 was numbered off; its lifecycle recorded 48 track points.
Typhoon Olive (197801) 的生命史始 at Northwest Pacific低The latitude海域, 整体路径呈现显著的“W进—N折—E撤”的复杂形态. formed初期 (4月15日至19日) , 系统自3.5°N, 149°E附近 toward W, 横穿Philippines以E洋面, 期间纬度缓慢N抬至9.6°N, DuringW移近20个经纬度, 显示出稳定的信风引导特征. 4月20日后, 随着系统接近S海E部及Philippines群岛以E海域, Moving direction发生关键转折. 在4月21日至23日期间, Typhoon 中心在113°E至119°E之间徘徊并逐渐N翘, 最终 at 4月23日到达15.9°N, 113.6°E附近, 此处可视为路径的W界极点. 随后, 受高空流场变化影响, Typhoon 转 toward NE, 快速远离陆地, 最终 at 4月26日18时在23.3°N, 133.3°E weakened into Tropical Storm并结束观测. 全生命周期内无Landfall记录, 主要活动区域集中在开阔洋面.
该Typhoon Intensity演变具有明显的“双峰”或“波动增强”特征. 初始阶段为Nameless, wind speed仅7m/s, 经过长达5天的缓慢加强, at 4月19日升级为Tropical Storm. 值得注意的是, 4月21日其Intensity曾短暂回落至23m/s, 但随后迅速反弹, at 4月22日重新 intensified into Severe Tropical Storm, 并在4月23日达到巅峰状态, max wind 录得43m/s, 定级为Severe Typhoon. peak intensity维持约24h后, 随着路径转 toward NEGo to 较高The latitude海域, 环境条件转差, 系统开始持续减弱, 至消散前wind speed降至20m/s.
Compared to the previous typhoon, the peak intensity of Olive in 1978 (Severe Typhoon, 43m/s) was between the historical maximum values. compared to the 1960s Olive (Super Typhoon) and the 1971s Olive (Severe Typhoon) , its intensity was slightly weaker or equivalent; but significantly strong at 1968 Olive (only to the Tropical Storm level) .
