Typhoon Forrest trajectory analysis
Track and Turning Characteristics
Typhoon Forrest (198622) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—N转—NE移”抛物线形态. formed初期 (10月13日至15日) , 系统位 at 12°N-14°N, 166°E-158°E之间, 稳定 toward NW, 日均移速较快. 10月16日至17日, 随着纬度提升至16°N以上, 路径逐渐由NW转为N, 并在17日20时到达最W端Position (20°N, 143.4°E) , 此处可视为路径的关键转 toward 点. 此后, 受中高纬度W风带引导气流影响, Typhoon 开始显著转 toward NE direction加速Moving. 10月19日后, 移速明显加快, 纬度从25.7°N迅速跃升至43°N, 经度 toward E回溯至168°E, 最终在温带气旋转化过程中消散. 全生命周期内无Landfall记录, 主要活动区域集中在开阔洋面.
Intensity evolution and historical comparison
该Typhoon 经历了完整的“ formed—爆发增强—巅峰维持—快速减弱”过程. 初始阶段为Tropical Depression, 气压缓慢下降. 10月16日08时升级为Severe Tropical Storm后, Go to 快速增强期, 仅用36h便从30m/s加强至50m/s, Pressure骤降57hPa至931hPa, at 10月17日20时达到Severe Typhoon级别的peak intensity. 巅峰状态维持Time较短, 随后因N上Go to 高纬冷水区及垂直风切变增大, intensity 迅速衰减. 10月18日wind speed降至40m/s, 19日晚进一步 weakened into Severe Tropical Storm, 最终在21日凌晨转化为Tropical Depression.
Compared with previous storms of the same name, Forrest in 1986 reached a moderately high intensity. Its peak central pressure of 931hPa and wind speed of 50m/s were significantly stronger than the 1992 storm of the same name, which had a central pressure of 995hPa and tropical-storm intensity, and the 1980 storm, which had a central pressure of 991hPa and severe-tropical-storm intensity. The 1986 storm was slightly weaker than Forrest in 1989, which reached a central pressure of 950hPa and severe-typhoon intensity, but far less intense than the extreme 1983 storm of the same name, which reached 876hPa and super-typhoon intensity. Despite causing no landfall-related damage, Forrest demonstrated considerable intensification potential over the open ocean, reflecting the typical intensity changes characteristic of Northwest Pacific typhoons in autumn.
