Typhoon Walt trajectory analysis
Track and Turning Characteristics
Typhoon Walt (199104) 的生命史始 at Northwest Pacific低纬度海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (5月6日至5月12日) , 系统稳定 toward NW, 纬度从6.5°N逐步攀升至14.4°N, 经度则由151.5°EW进至131.6°E, 显示出受副热带高压S侧引导气流控制的典型特征.
关键的转 toward 节点出现在5月13日至5月14日期间. 在达到最W端Position (约125°E-126.4°E附近) 后, Typhoon Moving direction发生显著改变, 由NW转为NE direction加速Moving. 5月14日后, 系统迅速远离大陆架, toward 开阔洋面移去, 最终 at 5月17日20时在36.5°N, 153°E weakened into Tropical Depression并结束监测. 整个生命周期长达11天半, track points多达47个, 表明其结构完整且生命史较长, 全程无Landfall记录, 主要在远洋活动.
Intensity evolution and historical comparison
Walt underwent a complete cycle of formation, intensification, peak intensity, and weakening. The system intensified into a tropical storm on May 7 and then rapidly strengthened, becoming a typhoon from a severe tropical storm in just two days. Its main intensification period lasted from May 10 to May 13, when its central pressure fell sharply from 950 hPa to a minimum of 920 hPa and maximum winds surged to 60 m/s, reaching super typhoon intensity. It maintained this intensity for about 36 hours, from 02:00 on May 13 until before 14:00 on May 14.
Starting on May 14, Typhoon Walt turned toward the northeast and moved into higher latitudes. Affected by changes in the environmental field, it weakened rapidly, downgrading from a super typhoon to a severe typhoon in less than one day and weakening into a tropical depression by May 17. Compared with the typhoon of the same name, the 1994 typhoon Walt reached a peak central pressure of 930 hPa, while the 1991 Walt had a minimum central pressure of 920 hPa and maximum winds of 60 m/s. This indicates that the 1991 Walt peaked slightly more intensely and was a stronger super typhoon system.
