Typhoon Opal Route Characteristics
Track and Movement Characteristics
Typhoon Opal (197017) had a brief life cycle, lasting about 3½ days from formation to dissipation. Its overall track showed a steady southwestward movement, with no notable turns or reversals. At the initial stage, the system was located over the eastern Philippines (15.1°N, 118.2°E), then continued west-southwestward across the central South China Sea. During its movement, its latitude gradually decreased from 15.1°N to 9.4°N, while its longitude shifted westward from 118.2°E to 107.9°E, covering a substantial horizontal distance. Notably, the typhoon made no landfall and remained over open waters throughout its life, eventually weakening and dissipating over the southwestern South China Sea east of Vietnam. This consistently directed track indicates that the steering flow was relatively stable and was not disrupted by weather systems capable of producing a more complex path.
Intensity Evolution Analysis
Opal的Intensity变化经历了“快速增强—巅峰维持—逐渐减弱”的典型过程. formed初期为Tropical Depression, wind speed12m/s; 在随后的18h内迅速加强, at 11月14日12时升级为Tropical Storm, 并在11月15日12时达到peak intensity, 定为Severe Tropical Storm, max wind 达25m/s. 巅峰状态维持Time较短, 仅约6h后, 自11月15日18时起开始减弱, 重新回落至Tropical Storm等级. 此后, 随着系统 toward SMoving, 环境条件可能趋 at 不利, intensity 持续衰减, at 11月16日18时降级为Tropical Depression, 直至最终消散. 整个过程中, 气压数据缺失, 但wind speed变化清晰反映了其生命周期的能量收支状况.
Comparison of Typhoon
Compared to other years of the same name Typhoon, in 1967 OPAL had reached Super Typhoon level, in 1997 and 1973 OPAL also reached Severe Typhoon and Typhoon level, both significantly strong at 1970 Severe Tropical Storm peak intensity. only in 1976 OPAL peak intensity is Tropical Depression, weak at this process.
