Typhoon Herbert, international code 198624, international name HERBERT, 1986 Northwest Pacific typhoon. Formed: 1986-11-07 18:00:00, ended: 1986-11-11 18:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 985 hPa, max wind: 30m/s.
Typhoon Herbert at 1986-11-07 18:00:00 at 13.2°N, 120.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 30 m/s (~108 km/h) and a minimum central pressure of 985hPa, recorded at 1986-11-09 06:00:00.
1986-11-11 18:00:00 After, Typhoon Herbert gradually weakened and was numbered off on 1986-11-11 18:00:00 was numbered off; its lifecycle recorded 17 track points.
Typhoon Herbert (198624) 的生命史始 at 1986年11月7日18时, formed at Philippines以W海域 (13.2°N, 120.9°E) , 初始状态为Nameless. 在整个生命周期内, 该Typhoon 呈现出稳定且持续的W行Moving特征, 未出现明显的转 toward 或折 toward 行为. 从经The latitude坐标序列分析, 其纬度变化幅度极小, 始终维持在13.1°N至14.4°N的狭窄带状区域内, 表明引导气流较为单一且稳定. During上, 系统从120.9°E一路 toward WMoving至109.4°E, 横跨S海中部海域, 总位移跨度超过11个经度. 值得注意的是, 尽管路径平直, 但在11月9日06时至11月10日06时期间, 纬度略有S压 (从14.0°N降至13.6°N) , 随后在消散前阶段 (11月11日) 又出现轻微N抬Trend. 全程无Landfall记录, 最终 at 11月11日18时在Vietnam以E近海 (14.4°N, 109.4°E) weakened into Nameless并结束监测.
Herbert的Intensity演变过程具有典型的“快速增强-平台维持-缓慢减弱”特征. 系统在 formed后24h内迅速加强, at 11月8日06时升级为Tropical Storm, 并在11月8日18时达到Severe Tropical Storm级别. 11月9日06时, 其Max Wind达到峰值30m/s, 并在此Intensity上维持了约36h (至11月9日18时) , 显示出较强的结构稳定性. 此后, 随着系统 toward W深入, 环境条件可能趋 at 不利, intensity 开始阶梯式下滑, 先后降格为Tropical Storm和Nameless.
Herbert's peak intensity in 1986 was equal to Herbert's peak intensity in 1983 (198312) and Herbert's peak intensity in 1980 (198005) with Severe Tropical Storm. This suggests that in the sequence of the name, Herbert's intensity upper limit is relatively stable, rarely developing to Typhoon and above.
