Characteristics of Typhoon Mireille
Track and Turning Characteristics
Typhoon Mireille (199120) 的生命史长达15天以上, 整体路径呈现典型的“W进-N折-NE toward ”抛物线形态. formed初期 (9月13日至17日) , 系统位 at lat 12.7°至15.5°N, 171.4°至155.9°之间, 稳定 toward WNW, 横跨W.Pac平洋广阔海域. 9月18日至22日期间, 路径纬度维持在15°N至16°N附近, 经度从152.5°E快速W移至135.3°E, 显示其受副热带高压引导气流影响, 保持稳定的W行Trend.
The key turning phase occurred from September 23–25. As the system moved north to 17.5°N and then west to 129.2°E, its movement direction began to change significantly. After September 25, the typhoon center gradually turned northward and reached approximately 28°N, 126.4°E on September 27. It then accelerated northeastward, rapidly moving to the high-latitude ocean near 43.5°N and eventually 48°N on September 28. The track never touched land, with no landfall recorded, making it a typical remote-ocean typhoon track.
Intensity Evolution and Peak Status
The typhoon underwent a complete cycle of intensity changes during its lifecycle. In its initial stage, it was a tropical depression with a pressure of 1008 hPa and wind speed of 12 m/s. Its intensity then increased steadily, strengthening into a severe tropical storm on September 17 and reaching typhoon status on September 18. From September 19–22, the system maintained severe typhoon intensity for an extended period, with wind speeds of 45–50 m/s and pressure falling to the 940–950 hPa range.
Peak intensity occurred on September 23–24, when the typhoon strengthened to a super typhoon, with maximum winds reaching 55 m/s and minimum central pressure falling to 930 hPa. Notably, after reaching peak intensity, the system remained a severe typhoon from September 25–27 (50 m/s, 940 hPa) despite moving northward, demonstrating remarkable structural stability. After entering the high-latitude cold-water region on September 28, its intensity rapidly weakened, dropping from typhoon to severe tropical storm. Pressure rose to 965 hPa and wind speed fell to 25 m/s before the system ultimately dissipated over the high-latitude ocean.
