Typhoon Nyatoh (202121) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先W后NE”的抛物线型转折特征. formed初期 (11月30日至12月1日) , 系统位 at 12.6°N-14.7°N, 139.2°E-135.8°E之间, 主要 toward W, The latitude缓慢N抬, During持续W进, 表明其受副热带高压S侧引导气流影响显著. 12月2日02:00至08:00期间, Typhoon 中心在135.6°E附近停滞并微调, 随后 at 12月2日17:00开始转 toward NE. 这一转 toward 点标志着引导气流的更替, 系统逐渐脱离低纬信风带, Go to W风带影响范围. 此后, Typhoon 加速 toward NE direction行进, 从12月3日02:00的137.5°E迅速移至12月4日05:00的144.9°E, 经度跨度超过7个经度, Moving速度明显加快. 全生命周期内无Landfall记录, 始终在洋面上活动.
Nyatoh的Intensity变化经历了“快速增强—巅峰维持—迅速减弱”的典型过程. 初始阶段为Tropical Storm级 (18m/s) , 在12月1日前Intensity波动较小. 自12月1日17:00起, 系统Go to 快速增强期, 由Severe Tropical Storm迅速发展为Typhoon , 并 at 12月2日08:00达到Typhoon 级上限 (38m/s) . 最为剧烈的增强的发生在12月2日17:00至12月3日08:00之间, 短短15h内°E, max wind 从40m/s飙升至55m/s, minimum pressure 从960hPa骤降至930hPa, 成功发展为Super Typhoon. 12月3日08:00为其生命史巅峰时刻. 随后, 随着The latitude升高至20.8°N以N, 环境条件恶化, intensity 开始衰减. 12月3日17:00降为Severe Typhoon, 12月4日02:00进一步 weakened into Typhoon , 直至消散前降级为Severe Tropical Storm. 整个过程展现了远洋Typhoon 在适宜海温下爆发式增强的特点, 以及高纬度冷空气或垂直风切变导致的快速消亡特征.
