Typhoon Agness, international code 197122, international name AGNESS, 1971 Northwest Pacific typhoon. Formed: 1971-09-15 06:00:00, ended: 1971-09-19 06:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 38m/s.
Typhoon Agness at 1971-09-15 06:00:00 at 18.8°N, 126.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 975hPa, recorded at 1971-09-18 06:00:00.
1971-09-19 06:00:00 After, Typhoon Agness gradually weakened and was numbered off on 1971-09-19 06:00:00 was numbered off; its lifecycle recorded 17 track points.
Typhoon Agness (197122) 的生命周期始 at 1971年9月15日06时, formed at Philippines以E洋面 (18.8°N, 126.3°E) , 终 at 9月19日06时在Taiwan海峡N部海域 weakened into Nameless. 从整体路径轨迹来看, 该Typhoon 呈现稳定的NW toward MovingTrend, 未出现明显的路径转折或回旋现象. 在初始阶段 (9月15日至16日清晨) , 系统Moving速度较慢, During变化微小, 主要 toward N微调The latitude; 自9月16日中午起, 随着Intensity提升, 其 toward W分量逐渐增加, 路径转为典型的NW direction推进. 整个过程中, Typhoon 中心始终位 at 海上, 无Landfall记录, 最终在接近China大陆SEcoastal 时消散.
Agness的Intensity演变具有典型的“快速增强, 短暂巅峰, 迅速衰减”特征. 系统在 formed初期维持NamelessIntensity (17m/s) , at 9月15日18时 intensified into Tropical Storm. 随后Go to 稳定增强期, 历时约48h, 依次跨越Severe Tropical Storm等级, 并 at 9月17日12时达到Typhoon 级别 (33m/s) . 巅峰状态出现在9月18日06时, 中心附近Max Wind达38m/s, 此时Position位 at 23.6°N, 122.5°E. 值得注意的是, 巅峰维持Time极短, 仅约6h后, 系统便开始显著减弱. 从9月18日12时起, wind speed在24h内由35m/s骤降至20m/s, 并在结束观测时回落至Nameless标准 (17m/s) . 这种快速的衰减可能与Go to 较高The latitude或受陆地摩擦及环境场变化影响有关.
In the named sequence of 'Agness', the 1971 Typhoon activity was at the Intensity at the middle level. Compared with the 2004 30th Typhoon Agness (top only for Tropical Storm), the 197122 Typhoon reached the Typhoon level, the intensity was significantly stronger. However, compared with the 1989 33th Typhoon Agness (top for Super Typhoon), its Intensity was significantly weaker. In addition, the 1986 and 1983 same-named Typhoon peak intensity was Severe Tropical Storm, slightly lower at the 197122 Typehoon's Typehoon grade peak.
