Typhoon Nina trajectory analysis
Track and Movement Characteristics
Typhoon Nina (198721) formed at Northwest Pacific低纬度海域, 整体路径呈现稳定的WNW走 toward , 未出现明显的转 toward 或回旋现象. 从11月19日20时在3.5°N, 159°E附近 formedTropical Depression开始, 系统持续 toward NW. 在11月19日至22日期间, Typhoon 中心纬度由3.5°N缓慢N抬至10.9°N, 经度则由159°E快速W移至139.1°E, 显示出较强的 toward W分量. Go to 11月23日后, 随着系统Intensity增强为Typhoon , 其Moving路径略微 toward N调整, 但仍保持W行Trend. 直至11月26日14时到达14.1°N, 118.8°E附近, 随后继续 toward NW direction深入S海N部海域. 整个生命史中, Typhoon 中心始终位 at 海上, 无Landfall记录, 最终 at 11月29日14时在19.3°N, 117.8°E减弱消散. track points分布均匀, 显示引导气流相对稳定, 未受复杂地形或剧烈环流调整影响.
Intensity evolution and historical comparison
Nina的Intensity演变经历了典型的“快速增强-巅峰维持-逐渐减弱”过程. formed初期为Tropical Depression (12m/s) , 在短短两天内迅速加强, 至11月21日已达Severe Tropical Storm级别 (30m/s) . 11月23日升级为Typhoon 后, intensity 持续攀升, at 11月25日20时达到巅峰状态, 此时中心最低气压降至945hPa, max wind 达50m/s, 评定为Severe Typhoon. peak intensity维持约一天后, 自11月26日起开始缓慢减弱, 气压回升至950hPa以上. Go to 11月28日后, 减弱速度加快, 由Severe Typhoon降为Typhoon , 进而转为Severe Tropical Storm, 最终在消散前降级为Tropical Storm (15m/s) .
Compared with previous typhoons of the same name, Nina in 1987 had significantly greater intensity. Data show that the peak intensities of the same-named typhoons in 1995, 1992, 1984, and 1978 were only tropical storm, tropical storm, severe tropical storm, and severe tropical storm, respectively, with minimum central pressures of 975 hPa or higher. By contrast, Nina in 1987 reached severe typhoon status, with a minimum central pressure of 945 hPa and maximum winds of 50 m/s, making it the strongest of the listed same-named typhoons and illustrating the extreme nature of typhoon development that autumn.
