Typhoon Dujuan, international code 202101, international name DUJUAN, 2021 Northwest Pacific typhoon. Formed: 2021-02-18 14:00:00, ended: 2021-02-22 05:00:00. Peak intensity: Tropical Storm, minimum central pressure: 990 hPa, max wind: 23m/s.
Typhoon Dujuan at 2021-02-18 14:00:00 at 7.3°N, 132.2°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 990hPa, recorded at 2021-02-19 17:00:00.
2021-02-22 05:00:00 After, Typhoon Dujuan gradually weakened and was numbered off on 2021-02-22 05:00:00 was numbered off; its lifecycle recorded 24 track points.
Typhoon Dujuan (202101) 的生命史始 at 2021年2月18日14时, formedPosition位 at lat 7.3°N, 132.2°的Northwest Pacific洋面. 从整体路径来看, 该Typhoon 主要呈现 toward WN的态势, 全程未发生Landfall. 在Moving初期 (18日14时至19日20时) , Typhoon 中心The latitude由7.3°N缓慢S压至6.5°N, During从132.2°EW移至129.9°E, 显示出明显的SW toward 分量, 这可能受到当时低层引导气流的影响.
值得注意的是, 2月20日05时出现了一个微小的路径转折, The latitude回升至6.6°N, 随后路径转为稳定的NW toward Moving. 从20日14时至22日05时消散前, Typhoon 中心纬度持续N抬, 从7.4°N升至10.7°N, During则快速W进至124.6°E. 整个生命史中, track points分布较为紧凑, Moving速度相对均匀, 无剧烈转 toward 或停滞现象, 最终在Philippines以E洋面减弱消散.
在Intensity变化方面, Typhoon Dujuan表现为“快速增强-维持巅峰-缓慢减弱”的特征. formed初期气压为998hPa, wind speed18m/s. 经过约30h的调整, at 19日20时达到peak intensity, 此时最低气压降至990hPa, max wind 增至23m/s, 等级维持为Tropical Storm. 此后, Typhoon 在990hPa的气压值和23m/s的wind speed上维持了约36h (至21日05时) , 显示出较好的结构稳定性. 21日14时起, Pressure回升至995hPa, wind speed回落至20m/s, Go to 减弱阶段, 直至22日05时进一步 weakened into 18m/s, 998hPa后结束code.
Historically, 2015 Dujuan (201521) and 2003 Dujuan (200313) both developed to peak Super Typhoon, minimum pressure low to 925hPa and 916hPa respectively; that is, weaker 2009 Dujuan (200912) , its peak intensity also reached Severe Tropical Storm level (980hPa) .
