The SummaryTyphoon Opal (international code 196431) is a 1964 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 87m/s, minimum central pressure 900hPa, not in China Landfall, 1964-12-16 was numbered off, recorded 30 track points.
Typhoon Opal, international code 196431, international name OPAL, 1964 Northwest Pacific typhoon. Formed: 1964-12-08 18:00:00, ended: 1964-12-16 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 900 hPa, max wind: 87m/s.
Typhoon Opal at 1964-12-08 18:00:00 at 5.8°N, 153.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 87 m/s (~313 km/h) and a minimum central pressure of 900hPa, recorded at 1964-12-12 18:00:00.
1964-12-16 00:00:00 After, Typhoon Opal gradually weakened and was numbered off on 1964-12-16 00:00:00 was numbered off; its lifecycle recorded 30 track points.
Typhoon Opal (196431) formed at Northwest Pacific低The latitude海域, 初始Position位 at 5.8°N, 153.4°E. 在整个生命史中, 该Typhoon 呈现出稳定的NW toward MovingTrend, 未出现明显的路径转 toward 或停滞现象. 从经纬度坐标序列分析, Typhoon 中心自E toward W横跨大洋, During从153.4°E持续W移至120.3°E, 纬度则由5.8°N缓慢N抬至17.1°N. 这种长距离, 单 toward 性的Moving轨迹表明其受副热带高压S侧引导气流控制显著, 且周围大气环境场较为稳定. 值得注意的是, 尽管Moving direction保持一致, 但在12月12日至13日期间, 随着纬度突破10°N并接近13°N, 其移速似乎有所调整, 随后在12月14日后纬度变化趋缓, 最终在Philippines以E海域减弱消散. 全程无Landfall记录, 属 at 典型的远洋型typhoon track.
Opal的Intensity演变过程极具爆发力, 展现了从Nameless到Super Typhoon的完整且剧烈的增强周期. 12月8日 formed时仅为15m/s的Nameless, 但在短短48h内, 即12月10日18:00, wind speed已飙升至53m/s, 晋升为Super Typhoon. 随后的两天内, intensity 继续攀升, at 12月12日18:00达到峰值, max wind 高达87m/s, 并维持该peak intensity长达约36h (直至12月13日18:00) . 这种长Time维持极端Intensity的特征在12月 formed的Typhoon 中较为罕见. 12月14日06:00后, intensity 开始急剧衰减, wind speed在12h内从69m/s降至38m/s, 显示出结构快速崩溃的特征.
In comparison, in 1964 Opel's Intensity had a overwhelming advantage over previously named Typhoon. in 1997 Opel's peak was only Severe Typhoon, in 1973 Typhoon, in 1970 Severe Tropical Storm, and in 1976 Opel even only reached the Nameless level.
