Typhoon Nanmadol, international code 201703, international name NANMADOL, 2017 Northwest Pacific typhoon. Formed: 2017-07-02 08:00:00, ended: 2017-07-04 17:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 988 hPa, max wind: 25m/s.
Typhoon Nanmadol at 2017-07-02 08:00:00 at 20.3°N, 126.8°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Tropical Storm intensity with max winds of 25 m/s (~90 km/h) and a minimum central pressure of 988hPa, recorded at 2017-07-03 08:00:00.
2017-07-04 07:40:00, Typhoon Nanmadol in Japan's Nagasaki Peninsula W section coastal Landfall.
2017-07-04 17:00:00 After, Typhoon Nanmadol gradually weakened and was numbered off on 2017-07-04 17:00:00 was numbered off; its lifecycle recorded 19 track points.
The life history of the 3rd Typehoon “Nanmadol” in 2017 is short, from formed to dispersed about 2 days 9h. Its path overall presents a clear NE toward MovingTrend, with the characteristics of typical sub-tropical high-pressure edge guiding airflow. in the initial phase (July 2, 08.00 to 23.00 p.m.) , Typhoon center at lat 20.3° to 24.2°N, between 126.8° to 124.4°, Moving direction mainly forNNW, length gradually W shift, latitude steadily N increase.
The key turn toward point appeared between the morning of July 3 and the morning of July 3.02am, centered at 24.8°N, near 124°, followed by length starting by W turn E (124°E -> 124.3°E) , marking the route from the NW line to NE line. Then, Typhoon accelerated toward NE, crossing the E Sea E area, straight to the Japanese region of Kyushu. July 4.07:40, Typhoon center in the Nagasaki peninsula W section coastal Landfall. After landfall, the system continued toward NE direction deep, finally at July 4th at 34.2°N, 136.3° decreased near.
在Intensity方面, “Nanmadol”表现为快速增强后维持巅峰, Landfall前缓慢减弱的特征. formed初期为Tropical Storm级 (18m/s, 1000hPa) . 7月3日02时至08时, 系统在短短6h内迅速加强, max wind 从20m/s增至25m/s, minimum pressure 降至988hPa, 达到Severe Tropical Storm级别. 此后直至7月4日14时, Typhoon 维持在Severe Tropical StormIntensity (25m/s, 988hPa) 长达30余h, 显示出较好的结构稳定性. Landfall后, 受陆地摩擦及环境因素影响, intensity 开始减弱, 7月4日17时降为Tropical Storm (23m/s, 992hPa) .
Its peak intensity is only Severe Tropical Storm, minimum pressure is 988hPa. In comparison, 2022's 14th 'Nanmadol' and 2011's 11th 'Nanmadol' both reached Super Typhoon level, minimum pressure is lower to 925hPa and 920hPa respectively; even 2004's 28th 'Nanmadol', also reached Severe Typhoon level (950hPa) .
