Typhoon Dianmu Trail Characteristics
Track Movement and Recurvature Characteristics
The life history of the 15th Typehoon “Dianmu” in 2021 is short, from formed to dispersed only about 39h. According to the observation data, its overall path shows a stable NW toward MovingTrend, with no obvious Landfall record or sharp turn toward.The initial phase (September 22, 17th to 23th, 08th) , system center position at lat 12.8° to 13.6°N, between 113.6° to 111.8°, Moving direction is mainly WNW, latitude increases slowly, longitude continues to decrease.
From 08:00 to 14:00 on September 23, its movement accelerated, with latitude rising rapidly from 13.6°N to 15.1°N and longitude shifting westward to 110.2°E, indicating strengthening steering currents. Its track then became more gradual, with the center oscillating slightly between 15.2°N and 15.8°N while continuing west-northwestward until reaching waters west of 107°E. The track remained smooth throughout, with no abnormal reversals or stagnation. It eventually weakened and dissipated near 15.8°N, 106.7°E at 08:00 on September 24.
Intensity evolution and historical comparison
The system in the formed earlyined Tropical Depression level, Pressure stable at 1002hPa, max windined at 15m/s. Until September 23, 17th, with Pressure dropped to 998hPa, max wind increased to 18m/s, the system officially upgraded to Tropical Storm, reached its peak intensity in the history of life. Within 24h, intensityined highly stable, air pressureined at 998hPa, wind speed stable at 18m/s. Until September 24,05th, air pressure rose back to 1000hPa, then at 08th quickly weakened into Tropical Depression, wind speed dropped to 13m/s, air pressure rose to 1006hPa, marking the structure of the system.
Its peak intensity is only Tropical Storm, minimum pressure is 998hPa. In comparison, 2016 and 2010 'Dianmu' have reached the Severe Tropical Storm level, minimum pressure is 978hPa and 980hPa respectively; and 2004 'Dianmu' has developed to Super Typhoon, minimum pressure is low to 910hPa.
