The SummaryTyphoon Vamco (international code 200311) is a 2003 Northwest Pacific typhoon; peak intensity Nameless, max wind 17m/s, minimum central pressure 997hPa, not in China Landfall, 2003-08-20 was numbered off, recording 9 track points.
Typhoon Vamco, international code 200311, international name VAMCO, 2003 Northwest Pacific typhoon. Formed: 2003-08-18 18:00:00, ended: 2003-08-20 18:00:00. Peak intensity: Nameless, minimum central pressure: 997 hPa, max wind: 17m/s.
Typhoon Vamco at 2003-08-18 18:00:00 at 18.8°N, 125.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Nameless intensity with max winds of 17 m/s (~61 km/h) and a minimum central pressure of 997hPa, recorded at 2003-08-19 18:00:00.
2003-08-20 18:00:00 After, Typhoon Vamco gradually weakened and was numbered off on 2003-08-20 18:00:00 was numbered off; its lifecycle recorded 9 track points.
The life history of the 11th Typhoon “Vamco” in 2003 is short, from formed to dispersed only about 48h. Observation data show that the system as a whole presents a stable NW toward Moving trajectory, with no obvious path turn or stagnation phenomenon. starting at PhilippinesE surface (18.8°N, 125.2°E) , the system rapidly toward NW direction advance, latitude in 24h from 18.8°N climb to 27.2°N, length from 125.2°EW to 120.9°E, the average speed is faster.
Until the end of life, the system crossed the Taiwan Strait Go to E Sea W area, continued toward NNW, and eventually reached the Zhejiang coastal to N area (30.5°N, 117.5°E) .
Intensity方面, “Vamco”始终维持在Nameless等级, 未能发展为Tropical Storm及以上级别. 系统在Moving初期经历了一个短暂的加强过程, Pressure从初始的1004hPa逐步下降, max wind 由10m/s增至17m/s. at 2003年8月19日18:00至20日00:00期间达到巅峰状态, 此时中心最低气压为997hPa, max wind 保持在17m/s. 随后, 受环境因素影响, 系统开始减弱, Pressure回升至1004hPa, wind speed降至10m/s, 直至监测结束.
In the history of other typhoons called 'Vamco', the 2009 and 2020 systems reached extremely high intensity levels, of which 2009 Vamco peak pressure was low to 935hPa, 2020 Vamco peak pressure was 940hPa, both Severe Typhoon or Super Typhoon level; even the relatively weak 2015 Vamco, its peak pressure also reached 995hPa, slightly strong at 2003 system.
