Characteristics of Typhoon Jangmi
Track and Movement Characteristics
The 2002 Typhoon Jangmi had a relatively short life cycle, lasting about 42 hours from formation to dissipation. Its track generally showed a marked northeastward trend and did not make a direct landfall. During the initial stage, from 14:00 on September 20 to 08:00 on September 21, the system was located between 22°N and 25°N over waters from 136°E to 139°E. It moved slowly west-northwest, with longitude decreasing from 139.4°E to 136.5°E and latitude increasing by about 3.2°. Its track then turned sharply, and from 14:00 on September 21 the system accelerated toward the northeast. After 08:00 on September 22, its movement speed increased substantially as the longitude-latitude span widened, rapidly moving from 29.7°N, 138.2°E to its final position at 34.8°N, 145.1°E. This indicates that midlatitude westerly-flow steering became increasingly influential. The system eventually became extratropical and dissipated over the open ocean.
Intensity evolution and historical comparison
In terms of intensity, Jangmi underwent a brief strengthening from a tropical depression to a tropical storm. Its initial central pressure was 1002 hPa, with maximum winds of 12 m/s. From 08:00 on September 21 to 08:00 on September 22, it gradually deepened, with the pressure falling to 987 hPa and wind speed rising to 20 m/s, its peak intensity. After reaching its peak, the pressure rose slightly to 990 hPa and remained stable, while maximum winds stayed at 20 m/s until the end. This shows that its structure became more stable during rapid movement but did not intensify further.
Compared with previous storms bearing the same name, the 2002 Typhoon Jangmi was relatively weak. Its peak central pressure of 987 hPa was higher than those of Jangmi in 2014 at 988 hPa and in 2020 at 992 hPa, indicating weaker intensity. It was, however, far weaker than Jangmi in 2008, which reached 910 hPa as a super typhoon, and Jangmi in 2026, which reached 970 hPa as a typhoon. Within the series of storms named Jangmi, the 2002 system was a moderate-to-weak tropical cyclone whose development was limited by its short life cycle and rapid changes in the surrounding environment, preventing it from becoming a more intense storm.
