Analysis of Typhoon Dot's track characteristics
Track and Movement Characteristics
Typhoon Dot (198521) 的生命史始 at Northwest Pacific低纬度海域, 整体路径呈现稳定的WNW走 toward . formed初期 (10月11日至13日) , 系统在5°N至10.3°N之间缓慢 toward NW, 经度从155°E迅速W移至148.5°E, 显示出较强的初始引导气流. Go to 发展阶段后 (10月14日至17日) , Typhoon 维持 toward WNW direction行进, 纬度在11.4°N至14.7°N区间内小幅波动, 经度则持续W进至129.9°E. 值得注意的是, 在10月17日凌晨达到peak intensity后, 系统并未出现明显的转 toward 或N上Trend, 而是继续 toward W穿越Philippines以E海域, 直至10月22日消散 at 103.2°E附近. 整个生命周期内, track points分布均匀, 未记录到Landfall行为, 属 at 典型的远洋型typhoon track.
Intensity evolution and historical comparison
Dot's intensity evolution featured a dramatic burst of rapid intensification followed by a gradual weakening. Starting as a tropical storm on October 14 (20 m/s, 995 hPa), the system intensified rapidly into a super typhoon within 48 hours. Especially between 08:00 on October 16 and 02:00 on October 17, central pressure fell further to a minimum of 893 hPa (note: the data table shows 897 hPa at 02:00 on the 17th, but the peak data gives 893 hPa as the minimum; the observed extreme in the series is used here, with the actual peak occurring near that window), while maximum wind speed surged to 70 m/s, securing its super typhoon classification. However, from 20:00 on October 17, as the system continued westward, intensity began to decline markedly: pressure rose back to 908 hPa and kept climbing, and wind speed gradually fell to typhoon strength of 35–40 m/s, ending its life as a tropical depression on October 22.
Compared with previous typhoons of the same name, the 1985 Dot had a decisively stronger intensity. Data show that the Dot typhoons of 1993, 1990, 1989 and 1982 all reached peak minimum pressures between 960 hPa and 971 hPa, with maximum intensity only at the common typhoon level. By contrast, Dot in 1985 dropped to a minimum pressure of 893 hPa with maximum wind of 70 m/s, far exceeding the intensity records of all other same-named typhoons, making it a remarkably severe typhoon case in the historical record.
