Typhoon Guchol, international code 201717, international name GUCHOL, 2017 Northwest Pacific typhoon. Formed: 2017-09-04 08:00:00, ended: 2017-09-07 17:00:00. Peak intensity: Tropical Storm, minimum central pressure: 998 hPa, max wind: 18m/s.
Typhoon Guchol at 2017-09-04 08:00:00 at 16.4°N, 128.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 18 m/s (~65 km/h) and a minimum central pressure of 998hPa, recorded at 2017-09-06 08:00:00.
2017-09-07 17:00:00 After, Typhoon Guchol gradually weakened and was numbered off on 2017-09-07 17:00:00 was numbered off; its lifecycle recorded 38 track points.
Typhoon Guchol (201717) has a short life history, from formed to dispersed for about 3 days 9h. Its overall path shows a stable NW toward MovingTrend, with no noticeable turn toward or stagnation phenomenon. Initial phase (September 4th to 5th morning) , system position at Philippines to E surface (about 128°E-125°E), latitudeined between 16.4°N to 16.7°N, longitude rapid W shift, indicated by the low-layer guiding airflow significantly affected. Go to September 5th after daylight, the path began toward N percentage increased, from 16.7°N rapidly to 19.5°N, while continuing toward W across the sea near the Strait.
It is worth noting that between 05:00 and 19:00 on September 6th, the Typhoon center varied very slightly in length (from 110.7°E slowly to 120°E), while the latitude jumped from 20.6°NN to 21.5°N, showing the characteristics of Moving slowing and the N toward segment dominated dispersion.
In terms of intensity, Guchol has alwaysined a weak level. The system was initially nameless (15m/s, 1002hPa) andined the intensity for up to two days of Time, with a slight fluctuation in air pressure. Until 10:00 on September 6, Pressure dropped to a minimum of 998hPa, max wind increased to 18m/s, until it was officially intensified into Tropical Storm, which is also the peak intensity in its history. However, this peak stateined only about 12h, then rapidly weakened back to Nameless (13m/s, 1002hPa) at 05:00 on September 7, until dispersed. The entire process was characterized by “weak formed, weak enhanced, rapidly weakened” characteristics, loose structure, lack of sustained energy support.
In 2012 Guchol developed into Super Typhoon, minimum pressure up to 915hPa; in 2023 Guchol also reached Typhoon, minimum pressure 960hPa; even weaker 2005 Guchol, its peak intensity also for Severe Tropical Storm (985hPa) .
