Typhoon Halong, international code 200804, international name HALONG, 2008 Northwest Pacific typhoon. Formed: 2008-05-16 14:00:00, ended: 2008-05-20 02:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 985 hPa, max wind: 25m/s.
Typhoon Halong at 2008-05-16 14:00:00 at 14.2°N, 117.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 25 m/s (~90 km/h) and a minimum central pressure of 985hPa, recorded at 2008-05-17 14:00:00.
2008-05-20 02:00:00 After, Typhoon Halong gradually weakened and was numbered off on 2008-05-20 02:00:00 was numbered off; its lifecycle recorded 28 track points.
The life history of the 4th Typhoon “Halong” in 2008 was short, from formed to dispersed for about 3 and a half days.The entire path showed a stable NE toward MovingTrend, with no apparent Landfall behavior or a sharp turn toward.Initial phase (May 16th, 14th to 17th, 11th) , system position at Philippines at E surface, the center coordinates from (14.2°N, 117.2°E) slowly moved from N to (15.8°N, 119.1°E), Moving direction is mainly NE, relatively sluggish.
Go to development maturity (May 17th 17th 17th to May 18th 05th) , Typhoonins Severe Tropical StormIntensity, path continues toward NE direction extension, latitude rises from 16.2°N to 17.3°N, length stretches to 121°E near. Then, influenced by high-air guided airflow, Moving speed slightly accelerated, path indicates toward more perpendicular toward E direction. May 18th 11th to 20th 02th, Center from (17.9°N, 122.5°E) rapid Moving to (24.9°N, 133.1°E), latitude range significantly increased, indicating the system toward Nward pushing while toward E increased, eventually weakened in the Northwest Pacific open sea area.
在Intensity变化方面, “Halong”经历了典型的“增强-维持-减弱”过程. formed初期为Nameless (16m/s, 998hPa) , 随后迅速加强, at 5月17日17时达到peak intensity, 定为Severe Tropical Storm, 中心最低气压降至985hPa, max wind 25m/s. 巅峰状态维持约12h, 期间气压稳定在985hPa. 5月18日11时起, intensity 开始波动下降, wind speed回落至20m/s, 气压回升至995hPa, 虽在19日05时有短暂反弹 (23m/s, 990hPa) , 但整体Trend为减弱, 直至生命史结束维持在Tropical Storm级别.
Data show that in 2002, 2014, 2019 and 2025 'Halong' reached Super Typhoon level, minimum pressure between 904hPa to 930hPa, respectively, much lower at 2008's 985hPa.
