Typhoon Amy, international code 197104, international name AMY, 1971 Northwest Pacific typhoon. Formed: 1971-04-29 06:00:00, ended: 1971-05-07 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 890 hPa, max wind: 77m/s.
Typhoon Amy at 1971-04-29 06:00:00 at 6.5°N, 154.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 77 m/s (~277 km/h) and a minimum central pressure of 890hPa, recorded at 1971-05-02 06:00:00.
1971-05-07 12:00:00 After, Typhoon Amy gradually weakened and was numbered off on 1971-05-07 12:00:00 was numbered off; its lifecycle recorded 34 track points.
Typhoon Amy (197104) at 1971年4月29日06:00在Northwest Pacific低The latitude海域 formed, 初始Position为6.5°N, 154.9°E. 其生命史全程未Landfall任何陆地, 始终在开阔洋面上活动. 从路径采样数据来看, 该Typhoon 整体呈现显著的“NW-NE”抛物线型Moving轨迹.
During the early period of formed (29 April to 1 May) , the system mainly toward NW, the length from 154.9°E quickly shifted W to 148.3°E, the latitude slowly increased N to 9.3°N. During the period from 2 May to 4 May, the Typhoon Go to turn toward transition, Moving direction gradually shifted from NW to N, then turned to NE. It is worth noting that on May 4th, 06:00 to 18:00, the length of which occurred a short turn (from 142.2°E to 143.8°E), showing path fluctuations in the turn toward process.
Amy's Intensity evolution has a typical 'fast enhancement, long maintenance, slow weakening' characteristic. Starting from April 29's Nameless (15m/s), the system rapidly strengthened within 48h, to May 1's 06:00 has reached Severe Typhoon level (48m/s) . May 2nd, 06:00, It peaked at Super Typhoon intensity with max winds of Up to 77m/s. Since then, from May 2 to May 5th, 18:00, Typhoon hasined Super Typhoon Intensity (wind speedined at 53m/s) for 84h, showing extremely strong structural stability.
In 1994, the 'Amy' peak intensity in 1977 and 1974 was only at the Tropical Storm or Severe Tropical Storm level respectively; namely, Amy in 1991 which equally reached the Super Typhoon level, Amy in 1971 with its 77m/s ultra high wind speed and up to several days of Super Typhoonining Time, showing more amazing energy release and durability in the history of the same name cycle.
