The SummaryTyphoon Walt (international code 199104) is a 1991 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 71m/s, minimum central pressure 915hPa, not in China Landfall, 1991-05-16 was numbered off, recording 51 track points.
Typhoon Walt, international code 199104, international name WALT, 1991 Northwest Pacific typhoon. Formed: 1991-05-04 00:00:00, ended: 1991-05-16 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 915 hPa, max wind: 71m/s.
Typhoon Walt at 1991-05-04 00:00:00 at 4.6°N, 151.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 71 m/s (~256 km/h) and a minimum central pressure of 915hPa, recorded at 1991-05-12 06:00:00.
1991-05-16 12:00:00 After, Typhoon Walt gradually weakened and was numbered off on 1991-05-16 12:00:00 was numbered off; its lifecycle recorded 51 track points.
Typhoon Walt (199104) 的生命史始 at 1991年5月4日00时, formedPosition位 at lat 4.6°N, 151.9°的Nameless阶段. 在初始发展阶段, 系统主要呈现 toward WN的Trend. 从5月4日至5月12日, 其The latitude由4.6°N逐步上升至14.4°N, During则由151.9°E持续W移至131.6°E, 显示出稳定的NW toward Moving路径. 这一阶段涵盖了从Nameless增强至Super Typhoon的全过程, Moving速度相对均匀.
It is worth noting that the system changed significantly after May 13 Moving direction. May 13 at 00 am at 16°N, 127.8°E, then continued toward NW direction for a short time Moving to May 14 at 17.6°N, 125.4°E. However, since May 15th, the path appeared a noticeable turn toward characteristic. May 15 at 00 am at 20.4°N, 124.7°E, until May 16 at 00 am had moved to 24.3°N, 128.6°E, the length began toward E withdrawal. Finally on May 16 at 12th, the Center reached 26.6°N, 133.7°E, marking Typhoon completed the turn toward process.
Walt's Intensity evolution presents a typical 'fast enhancement - peak maintenance - gradual weakening' characteristic. May 4 to 7 is a slow enhancement period, wind speed increased from 7m/s to 17m/s. May 8 is upgraded to Tropical Storm (23m/s) , May 9 reaches Typhoon level (35m/s) . In the following three days, the system experiences explosive enhancement, May 10 wind speed jumped to 56m/s, officially becoming Super Typhoon. May 12 reaches peak intensity, max wind reaches 71m/s (Note: May 12 in the data table is recorded as 69m/s, but summarizes that the peak is 71m/s, here summarizes the peak value as the norm, or according to the highest sequence
Starting on May 15, as the path turns toward and the latitude rises, the intensity rapidly decreases, falling to Severe Typhoon (48m/s), and at May 16 further weakened into Typhoon and Severe Tropical Storm. Compared with the same name 1994 Walt (199408) both reached the Super Typhoon level, showing that the name sequence has the potential to develop extremely high Intensity systems in a given year.
