Typhoon Agness, international code 198933, international name JACK, 1989 Northwest Pacific typhoon. Formed: 1989-12-20 00:00:00, ended: 1989-12-29 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 925 hPa, max wind: 64m/s.
Typhoon Agness at 1989-12-20 00:00:00 at 4.7°N, 155.1°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 64 m/s (~230 km/h) and a minimum central pressure of 925hPa, recorded at 1989-12-25 18:00:00.
1989-12-29 12:00:00 After, Typhoon Agness gradually weakened and was numbered off on 1989-12-29 12:00:00 was numbered off; its lifecycle recorded 39 track points.
Typhoon Agness (198933) formed at Northwest Pacific低The latitude海域, 初始Position位 at lat 4.7°N, 155.1°附近. 在生命史初期 (12月20日至22日) , 系统主要呈现缓慢 toward NW的Trend, 经纬度变化幅度较小, 表明其处 at 引导气流较弱的区域或受副热带高压边缘影响, Moving速度相对迟缓. 自12月23日起, 随着系统Intensity增强, 其Moving路径转为稳定的NW direction, 横穿马里亚纳群岛以E海域. 值得注意的是, 该Typhoon 在整个生命周期内未出现明显的Landfall记录, 始终在开阔洋面上活动. 路径后期 (12月27日后) , 系统继续 toward WNW并逐渐减弱, 最终 at 12月29日中午在lng 140°附近消散. 整体路径呈现出典型的“ formed-发展-巅峰-减弱”的单一路径形态, 无复杂转 toward 或回旋现象.
Agness的Intensity演变过程极具爆发力. 从12月20日的Nameless (10m/s) 起步, 经过约4天的持续加强, at 12月24日发展为Typhoon 级别 (41m/s) . 随后Go to 快速增强期, 仅在24h内 (12月24日12时至25日06时) wind speed由41m/s跃升至56m/s, 并 at 12月26日00时达到peak intensity, 录得Max Wind64m/s, 确立为Super Typhoon等级. 巅峰维持Time较短, 随后受环境因素影响, intensity 迅速衰减, 至12月27日中午已回落至Typhoon 级别 (33m/s) , 并在两天内进一步 weakened into Nameless.
In 2004 Agness only reached Tropical Storm level (lowest atmospheric pressure 990hPa), in 1986 and 1983 the same name Typhoon highest also only for Severe Tropical Storm or ordinary Typhoon level. in 1989 Agness as the 33rd Typhoon of the year, and in late December reached Super Typhoon level, showing rare late season high Intensity characteristics, its peak wind speed of 64m/s far above the same name, is one of the strongest Typhoon in the history of 'Agness' named Intensity.
