Typhoon Rosie trajectory analysis
Track and Turning Characteristics
Typhoon Rosie (199707) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (7月18日至20日) , 系统位 at 低纬度海域 (9.8°N-13.9°N) , 受副热带高压S侧引导气流影响, 稳定 toward NW. 随着纬度逐渐升高, 路径在7月22日至23日期间出现明显的转 toward 迹象. 坐标数据显示, 经度从133.2°E缓慢E退至131.9°E后开始回升, 表明系统在18°N-20°N附近完成了从NW行 toward NNE行的转折.
After moving into the middle and high latitudes from July 24, the typhoon accelerated toward the northeast, with its latitude rapidly rising from 22.4°N to 36°N and its longitude extending eastward from 132.4°E to 135.6°E. During its entire lifecycle, the typhoon made no landfall and remained over the sea, eventually weakening and dissipating east of Japan. This remote-ocean track kept its direct effects on coastal areas relatively limited, but provided ample moisture and energy for subsequent extratropical transition.
Intensity Evolution and Peak Status
Rosie’s intensity evolution went through three stages: rapid intensification, peak maintenance and gradual weakening. It initially formed as a tropical depression with a central pressure of 1004hPa. During just three days from July 20 to 23, the system underwent explosive intensification, with maximum winds surging from 20m/s to 55m/s and minimum central pressure plunging to 935hPa, reaching super typhoon status. This rapid deepening occurred over warm waters between 13°N and 20°N, indicating excellent thermodynamic support.
After reaching peak intensity at 14:00 on July 23, the storm began to fluctuate and weaken. Although it remained a severe typhoon on July 24 at 50m/s and 945hPa, its core structure was damaged as it moved north of 25°N, where sea temperatures dropped and vertical wind shear increased. After July 25, wind speed stabilized near 40m/s and pressure rose to 965hPa. The storm weakened rapidly after entering waters north of 30°N, was downgraded to a tropical storm by July 27, and ended its monitored lifecycle as a tropical depression on July 28. Compared with other typhoons of the same name or around the same period, Rosie displayed exceptional explosiveness, with a minimum central pressure of 935hPa and maximum wind speed of 55m/s, making it one of the most intense remote-ocean severe typhoons of the 1997 Pacific typhoon season.
