Characteristics of Typhoon Khanun
Track and Movement Characteristics
The life cycle of Typhoon Khanun (201720) began as a tropical depression at 20:00 on October 11, 2017, with its initial position at 16.6°N, 131.4°E. In the early stages, the system maintained a stable westward track, crossing northern Luzon in the Philippines and making its first landfall in the early hours of October 13. After entering the South China Sea, its path shifted significantly toward the northwest. Data from 14:00 on October 13 to 17:00 on October 15 show the latitude increasing from 17.4°N to 20.6°N and the longitude moving westward from 119.8°E to 112.6°E, indicating that after crossing Luzon, the system accelerated northwestward under the influence of environmental steering flows, heading directly for the Guangdong coast of China. It ultimately made its second landfall near Zhanjiang in the early hours of October 16, then rapidly weakened and was dissipated. The entire track was clear, with no significant stagnation or abnormal looping, reflecting the characteristics of a typical autumn typhoon.
Intensity evolution and historical comparison
The Typhoon underwent a typical “enhanced –ined – weakened” Intensity change process. During the crossing of Liu Song Island, the intensity wasined at Tropical Storm to Severe Tropical Storm level (wind speed 18-25m/s) . After going to the S sea heat zone, the system was rapidly strengthened, upgraded to Typhoon on the morning of October 15th, and reached its peak at 10 a.m. on the same day, the central minimum air pressure dropped to 960hPa, max wind to 40m/s, close to the Severe Typhoon lower limit.
Compared to previous typhoon, 2017 Khanun's peak intensity (960hPa/40m/s) between 2005 Khanun (945hPa/Severe Typhoon) and 2012 Khanun (990hPa/Tropical Storm) and weak at 2023 Khanun (935hPa/Super Typhoon) . Although its peak intensity has not reached Super Typhoon level, its rapid enhancement during the S Sea and its double Landfall path characteristics still have significant analytical value.
